Keeping Your Cummins Engine on The Job – Cummins Fault Code Explained

Hyster-Yale Materials Handling Corporation is an American company manufacturing a wide range of forklifts and material handling equipment. The company has a history that goes back to the 1920s when their first forklift truck was unveiled for commercial applications.

What has given Yale an edge over their competitors in this field is their diverse product portfolio. From forklifts powered by diesel, electric, LPG, and propane, they have it all. Today, you can get a Yale forklift that is ideally suited for any material handling application that you can think of. 

Before going into the various aspects of our Jaltest diagnostic software to read Yale forklift trouble codes, a quick word on fault codes, more commonly known as Diagnostic Trouble Codes (DTCs) is necessary. 

It is mandated by law that all modern vehicles and construction and material handling equipment must have an onboard computer that continuously monitors and tracks all their systems and components. In case of any malfunction, a trouble code, typically in alpha-numeric format will be shown on the display screen. 

At this point, you need to connect a diagnostic tool to the onboard computer to be guided through resolutions that will bring your equipment quickly back on the job. The advantage here is that any fault even if it is very minor is resolved at the earliest before it becomes a major problem. There is no need for extended downtime waiting for dealer-level certified engineers to show up to get your equipment back on track.

Our Jaltest maintenance tool for resolving Yale forklift trouble codes is good for a wide range of models. Whether it is for analyzing Yale GDP 50 MX trouble code or Yale ERP030-40VT trouble code, our software has you covered. 

Regardless of the model or the nature of the fault, you can be sure that you will get the best and most effective fault resolution procedures from the Jaltest Yale forklift diagnostic tool. It will help you navigate simple processes like fixing loose wiring or going through complex activities such as force regens, live data monitoring, full system scans, Yale propane forklift troubleshooting, and Yale forklift transmission troubleshooting. 

In this post, we will go through all the details of Yale forklift trouble codes and the capabilities of the Jaltest Yale diagnostic software. 

Yale Order Picker Troubleshooting Jaltest Diagnostic Software

While we have discussed the Jaltest software for Yale forklifts, it is no less effective for Yale order picker troubleshooting. There is a subtle difference between forklifts and order picker equipment. 

Order pickers or order picking equipment are specialized vehicles that lift operators to specific heights to pick equipment off the shelves or racks in warehouses to fulfill customer requirements. The equipment typically consists of a platform where operators can stand and pick individual orders off the racks. This is against the function of Yale forklifts that lift bales and pallets to high shelves for storage.

In both instances, the Jaltest diagnostic maintenance tool allows you to either select preventive maintenance options or scan by symptoms to clear Yale forklift trouble codes Whenever they arise. 

In the first instance, the Jaltest software allows you to undertake “full system scans” periodically that check the Yale material handling equipment for any potential malfunctions that are of a minor or temporary nature that might go away after a few driving cycles. Thus, you prevent any minor fault from becoming a major issue that necessitates downtime due to breakdowns. 

While carrying out full system checks, you are helped by live technical information and wiring diagrams that let you identify the precise fault and location. Hence, you can carry out optimized troubleshooting whenever a fault code arises.

The other option is fault resolution by symptoms that is, to investigate the fault when it arises. It is a solution to an issue and not preventive maintenance. For example, if a Yale GDP 50MX fault code pops up, you must focus on that code only and use the Jaltest maintenance tool to clear it. The software handholds you through the resolution so that your forklift is back on the job at the earliest possible time.  

Clearing Yale Forklift Trouble Codes By Propulsion Drives

Yale forklifts are available with various propulsion modes – electric, diesel, and propane. Hence, the procedure for Yale propane forklift troubleshooting will not be the same as diesel-powered Yale forklift troubleshooting. 

Let us take the two instances here. 

Yale propane forklift troubleshooting

The Jaltest software will guide you through the various aspects of Yale propane forklift troubleshooting, especially when the engine does not start. Probable causes include whether there is sufficient fuel in the tank and whether the pin in the tank bracket is lined up with the hole in the tank collar. This is because the liquid propane has to get sucked up by the fuel intake tube inside the tank.

Another reason that the engine will not start is improperly installed fuel couplers which are components that connect the fuel tank to the forklift’s fuel line.

Yale diesel engine troubleshooting

This section will be studied in detail as diesel-powered Yale forklifts are the most common among all propulsion systems used. 

All diesel engines have ab diesel particulate filter that checks emissions and traps impurities like soot inside it. When this soot accumulation gets to be very severe, the engine will not start and the equipment will go into limp mode. When passive regeneration or regens cannot clear the soot, forced regens have to be resorted to. 

When this fault code shows up in the display of the onboard computer, our Jaltest software will guide you through the process of forced regens to get your equipment back on the job without delay. The diesel particulate filter (DPF) typically gets clogged when a vehicle or material handling equipment such as a forklift goes through stop-go-stop operations and is rarely seen in long-haul traffic. 

When soot accumulation in the DPF goes beyond acceptable levels, a warning light goes on in the panel of the onboard computer. At this juncture, you must connect our Jaltest Yale forklift diagnostic tool to the computer port, select the model of the forklift, and navigate through the forced regens procedure as guided by the software. 

It must be noted here that the forced regens process is not standardized among different models of Yale forklifts. For example, the Yale GDP 50 MX fault code clearing for soot buildup in the DPF will not be the same for the Yale ERP030VT fault code reader. 

How does the Jaltest Yale forklift trouble codes reader help in carrying out forced regens. For one, it will inform the precise rev that the engine has to be run to burn away the excess soot in the DPF. Typically, it is at a very high rev for about 40 minutes for stationary vehicles and equipment such as forklifts. The resultant rise in the temperature of the exhaust gasses burns away the soot buildup and cleans the DPF. 

However, the filter must be cleaned manually when the severity of the soot accumulation is more than 75%.

Jaltest Yale forklift Diagnostic Software For Optimized Solutions

As we have seen, our Jaltest diagnostic tool can undertake fault-clearing activities regardless of the type of propulsion used by the equipment when you troubleshoot fault codes. You will be guided through several steps that will bring your malfunctioning forklift back on the job with dealer-level service. Any issue is accurately identified and cutting-edge solutions are provided for the resolution of any issue. 

Go through the diagnostic menu that will handhold you through the necessary solutions for any fault related to the systems or components. These include checking the injector and the wiring connections, the Electronic Control Unit, and more. 

What makes our Jaltest Yale forklift software stand above the competitors is the detailed technical and system information provided in the diagnostic menu. You get detailed technical data for full system scans, maintenance resets, and special functions (shortcuts). When you reach this stage of the diagnostic menu you get a wide range of options covering all facets of a Yale forklift including the central computer, hydraulic systems, electronic modules, power modules, instrument clusters, and more. 

There are provisions also for connecting and diagnosing issues with Cummings, Yanmar, and other major engine brands that power Yale forklifts. Hence, you do not need several software to handle the diagnosis of Yale forklift trouble codes, simply the Jaltest software covers most areas.

What helps is that every action carried out with the Jaltest software is backed by detailed diagrams of systems and components so that you are aware of precisely what to do for problem resolution. Among the critical systems where any malfunction is quickly resolved are the engine management control unit, multifunctional levers, reverse drive lever, and more. 

So comprehensive is the Yale forklift trouble codes reader that you can do away with manuals and bank on the software to get dealer-level services for any problems, from engines to hydraulics to transmissions, and more.

Summing Up

When you use the Jaltest Yale forklift software, you have an all-in-one tool that clears fault codes and brings forklifts back on the job seamlessly and flawlessly. All systems are covered and you even get component guides that advise you on whether one should be repaired or replaced when a fault arises. Backed by live information in real-time about the health of your forklift, this software is a must-have for owners of a fleet of Yale forklifts or order pickers. 

Our software is also very user-friendly. When you invest in one, apart from the software, cables, and other accessories, there is also a laptop that is available out of the box. To download and use the tool on the laptop there is no elaborate configuration and set up process involved. After the software is downloaded, plug the laptop into the onboard computer and you are ready for fault diagnosis and clearance. 

Finally, to keep up with technical innovations implemented in Yale forklifts by the manufacturers, we offer three updates to our software every year.          

Marine engines are complex systems and special care must be taken to make sure that they are in peak performance condition and do not let you down at crucial times. However, how do you make this happen? There is no magic wand, all that you have to do is to get our Jaltest marine scan tool and nip any potential issues or malfunction of your marine engine in the bud so that they do not become major problems and leave you stranded at sea. 

Before going in-depth into the various aspects of our marine engine scanner, it is important to understand the types of marine engines as the functioning of the maintenance tool largely depends on it. You can diagnose faults both for inboard engines and outboard engines with our marine diagnostic scan tool and get the best results from both scenarios.  

Inboard engines are typically installed in very large boats and yachts inside the hull of the vessel. When a diagnostic tool is used for fault analysis, it connects to the engine via a cable. On the other hand, outboard engines are mounted externally on the transom and connect to an outboard scan tool wirelessly via Bluetooth.

The benefit of having our marine diagnostic scan tool is that one software is good for both inboard and outboard marine engines. 

While this post will deal with marine engines in general, the focus will be primarily on the Jaltest outboard diagnostic scanner. 

Cutting-edge Features Of The Jaltest Outboard Motor Scan Tool  

When you invest in the Jaltest outboard motor scanner, you get a comprehensive package that consists of the outboard motor scan tool and software along with a laptop, adapter, and cables, as well as technical support. With the software, you can run commands that replicate what you get from dealer-level service engineers and carry out the same tests such as injector tests, fuel pump tests, and many more. 

Read and clear fault codes

Marine outboard engines have onboard computers that display malfunctions in the form of fault codes. These codes are in an alpha-numeric format and each represents a specific issue with the engine. However, fault codes are not standardized and vary between makes of outboard marine engines. 

Also known as Diagnostic Trouble Codes (DTCs), these codes are used to identify and diagnose issues with the marine engine’s systems. These codes can be accessed with the Jaltest outboard scan tool and valuable information is gathered for troubleshooting and repairs.  

Let us now go through some samples of marine engine fault codes.

P Codes: These are general codes used by many marine outboard engine manufacturers and indicate a wide range of issues.  

• P0123: Throttle Position Sensor Circuit
• P0300: Engine Misfire
• P20E8: Reductant Pressure Too Low 

SPN (Suspected Parameter Number) and FMI (Failure Mode Indicator): The next level after P Codes is SPN which manufacturers use to provide more specific information about the fault.

• SPN 5842: SCR Monitoring System Malfunction.
• SPN 1791: EGR Valve Control Circuit. 

Other examples of fault codes as identified by our marine scan tool.  

• 137: Pre Filter Oil Pressure Sensor Circuit Failed High.
• 141: Engine Oil Pressure Sensor Circuit - shorted low.
• 143: Engine Oil Pressure Low – Warning.
• 146: Engine Coolant Temperature High – Warning.
• 147: Accelerator Pedal Position Sensor Circuit - low frequency. 

Now that we have a definite understanding of fault codes for marine engines, let us explore the process of clearing them. 

Whenever a malfunction arises, it will be displayed on the Jaltest outboard motor scan tool once you connect it to the outboard engine. Now, the tool will prompt you to enter the manufacturer and model of the engine. The software will identify the specific malfunction and guide you on how to take corrective action. What helps is the detailed wiring diagrams that provide the exact position of the fault for analysis and correction.

The software also gives live technical information about the state of the engine in real-time. The advantage here is that you get an updated form of the fault, allowing you to easily troubleshoot the issue. 

It is always wise to maintain your outboard marine engine by changing filters and fluids to prevent future problems. Additionally, check carefully for any signs of rust on metal components as they can lead to electrical problems. Before starting a full-scale fault rectification procedure through our marine scan tool, do a preliminary inspection and check for loose wires or something similar.  

Calibration and parameter settings 

Almost all top-of-the-line marine engines have factory settings of vital systems and components that optimize their performance. These settings consider only standard operating conditions. However, it is not necessary that these must be followed only as key components can be calibrated and system parameters set to meet challenging operating scenarios. The Jaltest outboard scan tool calibrates and sets parameters that optimize so that your boat performs precisely as you want. 

You are thus in total control of the outboard engine and even the smallest facet can be set to match the required working conditions. Further, to ensure that your calibration and parameter settings cannot be tampered with access to them strictly controlled by a series of master passwords.

There are several tasks that can be carried out with the Jaltest marine diagnostic scan tool. You can adjust the trim, set up key parameters, adjust idle speeds for fuel efficiency, and use code injectors to quickly increase performance. Through these activities, you are not only avoiding fault codes but also making sure that your boat is perpetually in peak performance mode.  

Among the advanced features of the Jaltest software for calibration and parameter settings are the following:          

• Cutting-edge parameter settings to keep the engines running
• Calibrate digital throttles for instant responsive power
• Calibrate trim for smoother running and handling
• Set engine location for perfectly balanced operation
• Optimized for ghost trolling motor calibration
• Maintenance resets and parameter monitoring

You can also carry out actuation of components such as injectors tests, fuel pump operation, cylinder cut-out tests, and all other tasks required to diagnose and troubleshoot outboard marine engines. 

Deep Coverage Through Jaltest Marine Scan Tool

The Jaltest marine engine scanner offers deep coverage of marine engines making sure that they are always on the job and do not let you down at critical moments. While our software caters to both gasoline and diesel engines, it is the latter software that is more in demand. 

Several systems are taken care of by our outboard marine engine software including the electronic modules, engines, helm, powertrain, steering, and more. Technically advanced activities include calibrating trim and control levers, carrying out cylinder cut-out tests, and setting parameters. All testing data is recorded by the software at a very fast 90 minutes for 24 measurements.

Preventive Maintenance and Fault Correction with Jaltest Outboard Scan Tool

Our marine diagnostic scan tool has a very intuitive and user-friendly dashboard that has two very critical features. One is the scan “all” feature and the other is the “scan by symptoms” option. Let us analyze each of them as standalone entities. 

In the first instance, you carry out full system scans of all components and systems at pre-determined intervals. Any minor malfunction is immediately identified and quick corrective action can be taken to keep the engine running without the fear of it becoming a major problem. This is preventive maintenance that is crucial to the proper upkeep of your outboard motor. 

When you select “all”, you run checks on the various metrics selected by you from the menu. Among the parameters that you can select are the engine, electronic module, instrument cluster, powertrain, steering, and more. Once the system is fully scanned, you can be confident of trouble-free performance from your outboard marine motor. 

The other case is “scan by symptoms” where you select a system or component per the problem and work on it to set it right. Here, the Jaltest outboard motor scanner reads the fault code and guides you on the action to be taken to clear the fault code. The uniqueness of our software is that in case any component malfunctions, our software will inform you if it has to be replaced or repaired and in case of replacement, how to do so. 

Preventive maintenance with the Jaltest outboard diagnostic scanner is as critical a part of the trouble-free running of your engine as identifying faults and clearing them.

Summing Up

The Jaltest outboard scan tool offers deep coverage of marine outboard engines from top manufacturers, from Volvo Penta to Indmar, to Yamaha, and more. You get advanced troubleshooting solutions that rectify any fault codes irrespective of the seriousness of the issue. 

What sets our software apart from the others in this niche is the ease with which it can be set up. Unlike several software catering to fault diagnosis of marine outboard engines, the Jaltest maintenance tool is simple to set up. There is no elaborate configuration process, all that you have to do is download the software on the laptop provided, connect to the outboard engine wirelessly and you are ready for fault clearing activities. 

Finally, we provide three updates to the Jaltest marine diagnostic scan tool every year. This ensures that our software remains updated to deal with any technological innovations made to outboard engines produced by leading manufacturers around the world.

Let us first learn about Freightliner trucks, the Cascadia model, and the Jaltest scan tool for Freightliner before going to the various aspects of the diesel particulate filter for Freightliner trucks. 

Founded in 1929, Freightliner is an American semi-truck manufacturer. Originally launched as a truck manufacturing division of Consolidated Freightways, it was changed in 1942 to the Freightliner Corporation. Owned by Daimler AG from 1981 to 2021, the company is now a part of Daimler Truck subsidiary of Daimler Truck North America.

Freightliner has a wide product portfolio ranging from vans and medium-duty trucks, to heavy-duty trucks while the Freightliner Custom Chassis subsidiary manufactures bare chassis and cutaway chassis for multiple types of vehicles. Freightliner was the company that first introduced the cabover semi-tractors and today, the Freightliner Argosy leads the field in this category in North America. 

Freightliner heavy-duty Class 6-8 trucks are the most popular in this class in North America though Class 5-8 models of Freightliner trucks are not too far behind in popularity.  

The fifth-generation and most advanced in the Freightliner truck range is the Cascadia model which is optimized for high performance with several cutting-edge features. It is designed to reduce drag, increase airflow, and enhance fuel economy. 

The Jaltest scan tool for Freightliner helps to diagnose the chassis module, climate HVAC, and electronic control module, as well as actuate components such as fog lights, headlights, turn lights, and others. Among the most critical activities carried out is the fault code clearance of the diesel particulate filter in Freightliner semi-trucks that prevents them from going into limp mode. 

Various Facets of Diesel Particulate Filter (DPF) in Freightliner Trucks

This section will now focus on the DPF for Freightliner and will be considered so even if the name of the truck manufacturer is not mentioned when discussing the various aspects of DPF.

Diesel engines are more popular today than their gasoline counterparts as they are more sustainable and fuel-efficient. They are perfect for heavy-duty applications and are also widely used in light vehicles and passenger cars. However, over time, while diesel engine usage has skyrocketed, efforts have also been made to control emissions and reduce the environmental impact by developing after-treatment technology.  

This is where the Diesel Particulate Filter enters the picture.

What is the Diesel Particulate Filter in Freightliner 

The Freightliner DPF is a critical after-treatment device that catches and stores exhaust ash particles and other contaminants to reduce particulate matter emissions from diesel engines. 

The Functioning of DPF Filter in Freightliner

There are several varieties of DPFs available with the most common being the cellular ceramic honeycomb filters. This is because ceramic materials offer the best thermal resistance and stability. The ceramic honeycomb DPF has channels that are blocked at either end. The exhaust gas is forced through the DPF filter of Freightliner while the dangerous soot remains trapped in the filter. 

This is true for any model of the truck, whether it is the Freightliner M2 DPF filter or the DPF filter for Freightliner Cascadia. Since a DPF has limited capacity, soot builds up that needs to be removed, not only to ensure that the filter is working properly but in extreme cases to prevent the vehicle from going into limp mode. 

This soot removal process or Freightliner DPF cleaning is called forced regens, one of the vital activities that can be carried out with the scan tool for Freightliner. 

The Reasons For the Failure of DPF Filter Freightliner

DPF filter regeneration occurs only when certain conditions are met. These are conditions that typically impact engine temperature, vehicle speed, vehicle RPM, and exhaust gas temperature. The optimal temperature of the engine should be 250°C but for that, the vehicle should be in peak performance mode.

In a nutshell, then, any mechanical problem prevents DPF regeneration and causes soot accumulation and clogging. Hence, it is always wise to use the Jaltest scan tool for Freightliner to carry out a “full system scan” of the truck to check for any underlying fault codes that might be the cause of the soot buildup.  

Indications of a Blocked Diesel Particulate Filter for Freightliner

We have seen the functioning of the Freightliner DPF, its functioning, and the reasons for a DPF failure. Let us learn about how to recognize the systems of such a failure. 

Warning Lights

The most common indication is warning lights on the display of the onboard computer in Freightliner trucks. Fault code in alpha-numeric format will show the nature of the malfunction. You must now connect the Jaltest diagnostic laptop to the onboard computer and navigate through the software to carry out force regens to bring your truck back on the road.  

Increased fuel consumption

There is a possibility of failure of the DPF filter in Freightliner if you find an increase in fuel consumption. This is because the purpose of the DPF is the removal of exhaust fumes from the engine while trapping the soot particles. If the DPF is clogged, the exhaust gasses cannot escape the engine as quickly and efficiently as they should. 

This position weakens the engine as the exhaust gasses cannot escape as cleanly as required. It is the natural inclination of drivers at this point to step on the gas to increase the power of the engine. However, this has a negative effect as the engine consumes more power to eliminate the gasses, leaving less energy for acceleration, and thereby consuming more fuel. 

The engine will not start

The pressure of accumulated gasses in the DPF filter Freightliner M2 or any other model will prevent the engine from starting until the pressure is lowered. This is a blessing in disguise in a way as it stops the engine from starting and prevents damage to it. 

Problems with the Turbocharger

A blocked DPF filter in Freightliner M2, Cascadia, or others leads to various malfunctions such as gas or oil leaks since the accumulated exhaust gasses have nowhere to go. That is why it starts leaking directly from the turbocharger, resulting in more oil leaks and decreasing the overall efficiency of the turbocharger. 

Freightliner DPF Filter Cleaning – Maintenance Tips

The most critical part involving maintenance of the Diesel Particulate Filter and increasing its life cycle is to ensure that it can regenerate itself when soot builds up in it. There are three types of Freightliner DPF cleaning – passive, active, and forced regeneration. 

Let us check them out individually. 

Passive DPF Regeneration

Passive regeneration is a process that occurs when the temperature of the engine is higher than 350°C. When the vehicle is driven normally, this temperature burns away the excess soot from the Diesel Particulate Filter. 

Passive regeneration of the DPF filter Freightliner is a fully automated process and the driver will not even notice when it is going on. The only pre-condition is that the engine’s temperature must reach 350°C for it to happen and the vehicle must be driven at high speeds for long periods.

Active DPF Regeneration

Just like passive regeneration, active regeneration too is an automated process and starts when the soot levels in the DPF reach the limit of 45%. The pressure sensors in the engine management system now trigger the injection of raw fuel to the diesel oxidation catalyst (DOC), thereby increasing the exhaust temperatures and creating the conditions required for active regeneration. As in passive regeneration, active regeneration occurs when the vehicle is driven for extended periods at high speeds.  

Forced DPF Regeneration

In this process where Freightliner Cascadia DPF filter cleaning, or for that matter in any other model, takes place, it is necessary to use optimized scan tools such as the Jaltest Diesel Particulate Filter Freightliner diagnostic software. You will be guided by our scan tool for Freightliner on how to regenerate the filter.

This process can be carried out when the Freightliner truck is stationary in some models and the engine is revved up to high speeds to increase the temperature of the exhaust gasses. In others, on-road driving is required. 

However, there are several reasons why it is advisable to carry out forced regeneration when the truck is stationary. Self-clean of the DPF may be hampered by low fuel levels or system and component failure. If forced regeneration is required, the cause of the soot buildup must be traced and the system restored to working order first. It is essential to check the working of the pressure sensor when taking up Freightliner DPF cleaning. 

The DPF typically gets clogged in stop-go-stop operations generally seen in local urban cycle driving and in operations of construction equipment such as excavators and dozers. 

When soot accumulation in the DPF increases, a warning light appears on the onboard computer display. At this point, connect the Jaltest scan tool for Freightliner to the onboard computer port, select the model from the menu, and select the procedure to be followed for forced regeneration. 

The software will guide you on the engine rev to be deployed for forced regeneration. Generally, the vehicle must be driven at above 70km/h for about 10 minutes or at high rev for 40 minutes if stationary. The rise in temperature of the exhaust gasses burns away the soot accumulation. The Freightliner DPF filter cleaning must be done manually when the extent of soot accumulation is more than 75%.

Summing Up

The Diesel Particulate Filter for Freightliner is a crucial component and when maintained well and kept clean, it increases the engine performance and reduces fuel consumption. Use our Jaltest scan tool for Freightliner to carry out Freightliner DPF cleaning and keep your fleet and the DPF in peak operating mode. 

What makes our diagnostic software a cut above the others is the ease with which it can be configured and set up. Unlike other diagnostic tools in this niche, there are no elaborate configuration and setup processes, simply download the software onto the laptop, plug it into the onboard computer for scanning the health of your fleet, and you are good to go. 

Finally, we provide three updates to our software every year so that it can be in tune with technical innovations made to Freightliner trucks.    

Let us first understand what “Off-highway” or OHW refers to. They are vehicles that are typically designed to operate on unpaved surfaces and other challenging terrain such as project and construction sites or on farms and agricultural land. The point is that this equipment is ideal for unpaved roads instead of public ones.  

Some common examples of OHW are agricultural tractors, excavators, dozers, dump trucks, combine harvesters, and more in the construction and agricultural sectors. In industrial applications, apart from the equipment mentioned above, there are OHWs that are related to mining and forestry. OHW has a wide reach as the global market is heavily dependent on it for mechanization and replacement of traditional manual methods.

  If you have a fleet of OHW equipment, you will need a diagnostic tool to ensure that it is always performing at peak performance mode without any downtime. Breakdowns of OHW are costly and can set your project deadlines back, leading to substantial monetary loss. However, you need not worry about this adverse scenario as our Jaltest Off Highway diagnostic also plays a massive role in keeping your equipment on the job. 

Functions of the Jaltest OHW

Every modern vehicle and equipment, regardless of whether it is off-highway or those running on paved roads has an onboard computer that checks on the health of the vehicle and warns of any malfunction that might arise. This ECU or Electronic Control Unit is the heart of the equipment and keeps a tab on all systems and components. Whenever a system works outside set parameters a fault code flashes on the display screen of the onboard computer that is tucked away below the dashboard on the driver’s side.  

When this happens, you need to know what the fault code is about, what malfunction it indicates, and how to set it right. This is where your Jaltest off highway diagnostic tool comes in very handy. It is software that can be easily downloaded onto your laptop for early diagnosis of your equipment, thereby preventing any minor issue from blowing up into a major one. 

A quick word on fault codes will give you a better understanding of how our Jaltest off-highway diagnostic software works. 

Fault codes, also known as Diagnostic Trouble Codes (DTCs) are in alpha-numeric format with each code signifying a specific issue with the equipment. A few examples related to heavy construction equipment will help us understand fault codes better.      

P Codes: Indicate a problem with the powertrain (engine, transmission, drivetrain, fuel system).

• P0442: A small leak in the evaporative emission control system.
• P0606: A malfunction in the power train control module (PCM).
• P0101: A fault in the mass air flow (MAF) sensor or circuit.
• P0706: Fault in the transmission range sensor circuit range. 

C Codes: Indicate a problem with the chassis (steering, suspension, braking). 
B Codes: Indicate a problem with the body (parts in the passenger compartment). 
U Codes: Indicate a problem with the vehicle's onboard computers and integration functions. 

Now suppose one of these fault codes shows up on the display panel of the onboard computer. You have to now link up our Jaltest heavy equipment scan tool to it and the software will handhold you through the rectification solutions required to get your equipment back on the job at the earliest.

Jaltest Construction Truck Diagnostic Tool

We have explored the various aspects of heavy construction equipment and a sample of their fault codes too. As a continuation, let us in a nutshell, go through the Jaltest construction diagnostic tool with special reference to trucks. 

The Jaltest off highway maintenance tool is good for almost all major brands of trucks used in the construction industry today. These include Kenworth, Paccar, Mack, Freightliner, Allison, Peterbilt, Cummins, Detroit, Bendix Western Star, Volvo, International and more. 

When you use our Jaltest OHW tool you have one software that works for all brands of construction trucks. Hence, you do not need several maintenance tools if you have a mixed fleet of trucks. The software will make sure that they are on the road without a break, more so if you carry out preventive maintenance, the details of which we will come to in the next section of this post. 

Our software offers comprehensive solutions for varying malfunctions that cover all systems and components of construction trucks. The Jaltest off highway software covers engines, hydraulics, transmissions, brakes, lights, and more. When you connect the Jaltest software to the onboard computer, you get live technical information in real-time about the health of the truck and whether all systems are performing as they should. 

You can also undertake critical activities like speed limits and idle speeds, code injectors, and bleed braking systems for all types and makes of heavy-duty construction trucks. Further, with the Jaltest OHW diagnostic software, you can carry out system scans such as after-treatment and other resolutions for antitheft, brakes, electronic control modules, engines, hybrid systems, safety, and transmissions.

What helps is the user-friendly and intuitive features of the Jaltest OHW diagnostic tool. You are handheld through all rectification solutions in an easy-to-understand way. For instance, you get detailed wiring diagrams of all systems that help you to seamlessly locate the position of the fault and take quick action that is at par with what is provided by certified engineers at the dealer level. 

You do not have to go through bulky manuals, your truck is brought back on the job from your premises only. Check out some samples of what the Jaltest construction equipment diagnostic software has to offer in terms of optimized and cutting-edge solutions.

• Restarts the connection when communication is lost with systems in different sections of the application.
• Displays battery voltage and configures fault code display during the system scan function.
• Configures measurement groups in the data recorder function. 

In a nutshell, then, the Jaltest off-highway is a must-have tool for owners of heavy construction equipment and trucks that are designed to perform flawlessly on challenging terrain. 

Jaltest Off Highway – Troubleshooting vs. Preventive Maintenance

The Jaltest OHW diagnostic software is highly optimized for construction and other OHW equipment. In fact, you can carry out activities that will keep your fleet on the job. Let us now check two functions that make our maintenance tool a leader in its class. 

The first is the troubleshooting function where any fault code is quickly identified and solutions provided in the software. You will first be prompted by the software to input the make and model of the equipment and then, when connected to the tool, the fault code will show up on your laptop. From there, you will be guided through troubleshooting the issue to get highly effective corrective solutions to clear the fault code.

The fault codes may be related to the engines, hydraulics, transmissions, or any other systems or components. In case any part causes trouble, you will be informed whether it needs to be replaced and how to do so, or simple repairs will do. The cutting-edge resolutions offered by the Jaltest off highway diagnostic software “scan by symptoms” option makes it a leader in its class. 

The second option is preventive maintenance and this is a very crucial one to make sure that your equipment does not face frequent breakdowns. There is a feature in the Jaltest OHW that allows you to carry out full system scans at regular intervals just to estimate the condition of the equipment. This scan of all systems and components may throw up issues that are not reflected in the fault code list but might become major ones if left unattended for long. This pre-empting of faults is what will keep your equipment always in peak performance mode. 

Jaltest OHW Diagnostic Software and Force Regens

Forced regen is a critical activity that is carried out by Jaltest off highway. It is done when soot accumulates in the Diesel Particulate Filter (DPF) of diesel engines and passive regens alone are insufficient to clear it. When the problem becomes severe, the equipment will go into limp mode as the engine will stop functioning.

When this issue arises, the Jaltest software has to be connected to the onboard computer to be guided on how to clear the accumulated soot. Basically, it involves running the engine continuously for about 40 minutes at a rev that will be informed by the software. The increase in temperature burns away the soot and the fault code is cleared. 

This problem is typical to diesel engines only and in stop-go-stop operations as seen in construction equipment such as dozers, excavators, wheel loaders, and more. It is rarely seen in diesel engines that run for extended periods such as long-haul buses.
