A Guide to The Mack Truck Fault Codes List – Everything You Need To Know

While opening this review on the Jaltest marine diagnostic software, the first question that will pop up in the reader’s mind is whether this tool is optimized for inboard or outboard marine engines. Hence, the connection between marine engines in general and the Jaltest marine motor diagnostic tool will be dealt with first. 

Marine motors are complex systems and require a great deal of attention if you want them to run at peak efficiency and not get stranded on the high seas at any time. Periodical checks with our Jaltest marine diagnostic tool will ensure that any minor issue is identified quickly and resolved before it becomes a major issue. 

Inboard marine engines are fitted inside the hull of the vessel in large boats and yachts. Outboard engines are installed externally on the transom and are seen in small boats. When you see a jet ski whiz past you, that is an outboard engine. 

The way in which our Jaltest marine scan tool reads the data is different for the two types of engines too. For inboard engines, the Jaltest marine scanner is connected to the motor via a cable while for outboard engines the connection is established wirelessly over Bluetooth or Wi-Fi. Apart from this aspect, the diagnosis and maintenance of engine health are almost the same as the Jaltest tool.       

Jaltest Marine Code Reader and Cutting-Edge Diagnostics

How does our Jaltest marine code reader work? To understand it better, a brief look at what is a fault code is necessary. 

All modern marine vehicles, equipment, or vessels have an onboard computer that continuously tracks the health of the systems and components. Whenever a malfunction occurs, it is flashed on the display of the onboard computer as fault codes, typically in alpha-numeric format. 

At this point, you must connect the Jaltest marine code reader to the marine motor to interpret the fault code, identify what is wrong, and be guided on the fastest rectification to get your boat on the move again. The capabilities of the Jaltest marine software will be discussed later in this post. 

Here are some examples of marine fault codes, also known as Diagnostic Trouble Codes (DTCs). However, fault codes are specific to the make and models of marine engines and the following is of Volvo Penta marine engines.   

• Coolant Temperature (Code 6.1, PID/SPN 110): Caused when the coolant temperature is too high.
• Oil Pressure (Code 6.6, PID/SPN 100): Caused when the oil pressure is too low.
• Piston Cooling Pressure (Code 6.7, PPID 8/SPN 520192): Caused when piston cooling pressure is too low.
• Battery Voltage, CIU (Code 6.9, PID/SPN 158): Caused either when there is a short circuit to negative, a faulty alternator, or a faulty battery/battery cable.
• Crankcase Ventilation Pressure (Code 7.7, PID/SPN 153): Crankcase ventilation pressure is too high.
• Injection Pressure (Code 8.3, PID/SPN 164): Caused by either fault in the fuel pump, fuel supply, harness, or sensor.
• Pressure Valve (Code 8.3, PSID 97/SPN 679): Caused by leakage in the pressure release valve, the pressure release valve being stuck in an open position or being stuck in a closed position.
• Preheating Sensor (Code 8.6, SID 70/SPN 729): Caused by either a fault in the cable harness or in the preheating relay.

Once the fault code is seen and the onboard computer is linked to our Jaltest marine diagnostic software, the resolution process begins. Since fault codes are brand and model-specific, this is the first thing that you have to input in the software. 

Our maintenance tool then takes over and helps you to navigate the resolution procedure. You will get live technical data and information in real time so that you are updated about the issue. Further, we offer detailed wiring diagrams of systems and components so that you know the precise location of the fault and the exact nature of the malfunction.

It is advisable to do a preliminary check of outboard engines before using our Jaltest marine maintenance tool. Often, temporary fault codes crop up that do not require complex solutions but a cursory check of the engine only. Change filters and fluids periodically to thwart any possible future problems and verify for any rust on metal components that might show up as a fault code related to electrical issues.

The Jaltest marine diagnostic tool offers deep coverage maintenance of inboard and outboard marine engines of all leading makes such as Volvo Penta, Indmar, and more. Even though our software works equally well for petrol and diesel engines, it is the latter version that is more in demand.         

Among the outboard marine motor systems that are provided deep coverage by our Jaltest marine scan tool are 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. 

Additionally, all testing data is recorded by the software at a very fast 90 minutes for 24 measurements. Our Jaltest marine maintenance tool provides comprehensive system checks and diagnostics such as cylinder balance tests, advanced data graphing, and compression tests.

What gives our Jaltest marine diagnostic tool an edge over others in this niche is the user-friendly diagnostic menu that handholds users through every aspect of marine engine troubleshooting. Through live data about a malfunction, the point of a fault can be quickly traced and corrective action taken.  

From the diagnostic menu, you can directly choose a specific metric for fault rectification that includes the engine, electronic module, instrument cluster, powertrain, steering, and more. Any one parameter can be selected for fault clearance or all of them can be scanned through full system scans to find any fault at source and clearing it before it leads to a breakdown. 

Our Jaltest marine software helps boat owners carry out several technically advanced activities. They can adjust the trim, set up key parameters, adjust idle speeds for fuel efficiency, and use code injectors to quickly increase performance. With such thorough checks, you not only can rectify fault codes whenever they arise but can also carry out preventive maintenance to pre-empt future issues, ensuring the top performance of your marine vessel.

Marine Calibration with Jaltest Marine Diagnostic Software

Marine vessels have intricate systems and instruments that allow precise navigation, safety, and an unbroken chain of communication. These are critical when you are miles out at sea. However, set parameters of these aids often drift out of required tolerances due to environmental and temperature changes, humidity, and wear and tear. 

With our Jaltest marine maintenance tool, you can calibrate your instruments to ensure that they are within the range required for safe navigation. There are several types of calibration services that you will get from our maintenance tool.

The first is on-site calibration where you calibrate equipment and instruments directly on the vessel with the Jaltest marine software. This process ensures that you can carry out calibration while you are on the move and do not have to wait for dealer-level certified service engineers to come abroad. You can thus maintain valid certification of equipment without a break.

The second is the calibration of gas supply that tests and calibrates gas detection instruments where suppliers offer several options of flow rates and gas mixtures that are customized for the maritime industry. It helps to get accurate calibration of multi-gas detectors. 

Finally, the incorporation of innovative and technologically advanced features into equipment meant for calibration has led to automated and superior equipment calibration services. You can monitor the health of the systems and components of the vessel remotely and carry out calibration activities from the shore.

In this post, we will explore the various intricacies and capabilities of the Jaltest semi-truck scan tool as well as the commercial and medium-duty truck scanner and diagnostic tool.  

But first, what is the difference between a semi-truck, and others such as heavy-duty, medium-duty, and light commercial trucks?

A commercial truck or a heavy to medium-duty truck is a straight truck with the whole vehicle resting on a single chassis. A semi-truck, on the other hand, has two distinct parts, the cab and the trailer connected via a fifth wheel. The straight truck is easier to handle than a semi-truck due to its single chassis. 

However, though driving a semi-truck requires greater driver expertise, it is more versatile as it can carry loads not only heavier than straight trucks but of various configurations also as the load rests on an open trailer and is not boxed in. The initial investment on semi-trucks is substantially higher than on straight trucks but this is more than made up by higher load-carrying capacity per trip. 

Functions of The Jaltest Commercial Truck Scanner  

Our Jaltest commercial truck diagnostic tool is optimized for over 100 makes of semi-trucks and trucks. These include Kenworth, Paccar, Mack, Freightliner, Allison, Peterbilt, Cummins, Detroit, Bendix, Volvo, International, and more. Hence, the benefit here is that with one software, you can diagnose a mixed fleet of trucks without the need to invest in various diagnostic tools. 

The Jaltest commercial and semi-truck diagnostic software allows you to perform maintenance activities and undertake resolutions to complex issues. Hence, not only can you ensure that any minor malfunction is quickly solved before it becomes a major issue but can also troubleshoot problems with all major systems and components such as the engines, brakes, hydraulics, transmissions, body computers, and more. 

Our Jaltest semi-truck diagnostic software identifies the fault codes of the vehicle, interprets them, and carries out resolutions that are no less than dealer-level servicing. Since problem identification and resolutions are done on the premises instead of waiting for the dealer’s certified engineers, precious time is saved in getting the truck back on the road again.    

It is essential here to elaborate on what are fault codes. It is mandated by law that all vehicles, construction, material handling equipment, and farm machinery must have an onboard computer called the Electronic Control Unit (ECU). It tracks and monitors the various electronic systems and components and the overall health of the vehicle. Whenever a problem arises, it is shown on the display screen of the onboard computer as a fault code.

Our semi-truck computer scanner works through sensors placed throughout the vehicle. These process the data in the software and then send output signals to actuators that perform set actions. The warnings are sent as fault codes, generally in alpha-numeric format, and are seen on the onboard computer display panel placed below the dashboard on the driver’s side. 

Whenever a fault code is seen, connect our semi-truck scan tool to the onboard computer. It will read the fault code, interpret it, and recommend corrective solutions. Temporary fault codes generally go away within a few driving cycles but if they persist, the software will handhold you through more complex solutions till the fault codes are cleared. 

Cutting-Edge Capabilities of Jaltest Commercial And Semi-Truck Scan Tool 

When you use the Jaltest commercial truck diagnostic scanner there are several options that make sure that all systems and components come under the ambit of fault code clearance. When the warning lights start flashing on the onboard computer screen, connect our semi-truck scan tool to check the fault code, what it stands for, and how to resolve the malfunction. You need to scan by symptoms to understand what the fault is and how to rectify it at the earliest possible time.

Once you go for fault code clearing, you will be offered a host of solutions such as maintenance data, vehicle data, injector coding, VGT (Variable Geometry Turbocharger), and more. This data can be monitored live in real-time so that you get updated information about the health of the vehicle and the precise nature of the fault. You will also be advised on the mode of dealing with faulty components and whether they should be replaced or repaired. 

Our Jaltest commercial truck scanner has an edge over others in this niche and is a cut above our competitors primarily because of the large range of functions embedded in the software. For example, you can actuate body components, calibrate VGT and code injectors, calibrate transmissions, get wiring diagrams, technical information, component replacement instructions, repair times, and more.

Moreover, you can calibrate systems and set parameters to get the best performance from your vehicle under specific running conditions. All trucks, whatever their capacity or configuration have systems calibrated and parameters set during manufacture to perform under standard driving conditions. 

However, your truck might need to run under completely different conditions, and hence you need to alter the settings to get the most out of your vehicle. Under these circumstances, our semi-truck scan tool has a critical role to play. You can configure systems and set parameters for engines, hydraulics, transmissions, and more to get optimized performance from your vehicle. 

You can bank on the Jaltest commercial truck diagnostic scanner for resolving any issue, starting from simple jobs like fixing a loose wire to more complex tasks such as forced regens.

Forced Regens and Jaltest Commercial Truck Diagnostic Tool

It is mandated by law that all diesel engines have a Diesel Particulate Filter (DPF) through which emission gasses are passed and released from the vehicle. The DPF captures soot and particulate matter and the cleaned gas is put out. However, if the truck does not run at high speeds, soot will accumulate in the DPF as the temperature of the exhaust gasses is not sufficient to burn away the soot.

This results in the DPF getting clogged with soot and particulate matter, thereby lowering the running efficiency of the truck. Drivers need to rev the engine more to get power from the engine leading to lower fuel efficiency and added stress on the engine.

When passive regens are incapable of keeping the DPF clean, forced regens must be taken up. You will be guided in this activity by the Jaltest semi-truck diagnostic software and you have to simply follow the instructions in the software. 

Forced regens entail running the engine on high rev for about 40 minutes, an action that raises the temperature of the exhaust gas and burns away the accumulated soot. You will be handheld by our diagnostic tool and informed about the rev of the engine required ranging from High to Very High and the duration that it has to be run.

Forced regens is a very critical activity in the maintenance of diesel engines as left unattended, soot buildup might cause the engine to seize up and go into limp mode in extreme cases. 

Features Of The Updated Version Of Jaltest Truck Diagnostic Tool  

The latest version of our Jaltest semi-truck scan tool has several cutting-edge features that make it a leader in this field. It is also in sync with the technical innovations constantly being made to the systems and components of commercial trucks.

Here are some examples of the advanced capabilities introduced in our commercial truck diagnostic software.       

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

This makes the Jaltest Commercial and semi-truck scan tool a powerful medium to keep your trucks on the road without breakdowns.

Before going into the various aspects of the Case IH code reader, a brief overview of the Case IH company will help us know about their products and how the Jaltest fault code reader helps keeps them on the job. 

Case IH is a leader in the agricultural machinery niche with a wide range of products including combines and harvesters, tractors, hay, and forage equipment, planting and seeding systems, sprayers and applicators, and more. Case IH, an American company was founded in 1985 but later merged into J.I. Case with the present owners being the American-Italian corporation CNH International.

Even though manufacture and distribution of agriculture equipment forms the foundation of Case IH business, the company also provides optimized customer support to farmers and commercial operators. This done through sale of spares and dealer-level servicing through a large network of distributors and dealers in North America. 

The quality, ruggedness, and dependability of Case IH equipment is unmatched and this has led to awards galore being conferred on it by the American Society of Agricultural and Biological Engineers.

A special mention must be made here of the Case IH Magnum and Maxxum Series tractors that are universal powerhouses. It will help to analyze later in this post the various facets of the Case Magnum fault codes and Case Maxxum 125 fault codes. 

The Magnum series tractors are high-tech machinery with the capability to configure precision farming functionality, tractor systems, and connectivity with integrated solutions without a drop in power or performance. The Maxxum series offers powerful 4- or 6-cylinder engines from 125 to 150 hp. The Maxxum 150 tractor is the smallest and lightest tractor in the industry with a six-cylinder engine of this power output.

We will now go into the details of the Case IH code reader to explain how our Jaltest Case IH diagnostic software helps maintain your Case IH agricultural equipment in peak performance mode without downtime for breakdowns.

What Are Fault Codes On Case IH Farm Machinery

Why is having our Jaltest Case IH code reader so important when you have a fleet of this company’s farm machinery? 

Every modern vehicle or equipment has an onboard computer. It tracks the health of all systems and components onboard and warns users of any malfunction through fault codes. These codes are specific to the make and model of the equipment and are related to the systems such as engines, transmission, brakes, hydraulics, and more. Here are a few examples of Case Magnum fault codes related to the engine.    

• 3001: Foot Throttle Sensor ‐Signal Not Plausible.  
• 3002: Foot Throttle Sensor ‐Signal Above Range Max.  
• 3003: Foot Throttle Sensor ‐Signal Below Range Min.  
• 3004: Foot Throttle Sensor ‐ No Signal ‐ Error  
• 3006: Coolant Temperature Sensor ‐Signal Not Plausible (Compared with Engine Oil Temperature)

Now, in case of a malfunction, one of these Case IH Magnum fault codes will show up on the display of the onboard computer, typically tucked away below the dashboard. 

This is where the Jaltest Case IH code reader comes into the picture. Once a fault code is shown, connect the Jaltest diagnostic software to the onboard computer and you can see the specific fault code along with the interpretation on the laptop. At this stage, when you want to clear the fault code, the software will handhold you through the resolutions needed to get your equipment back on the job in the earliest possible time. 

The fault codes, also known as Diagnostic Trouble Codes (DTCs) are either temporary or permanent in nature. When a minor malfunction appears and goes away within a few driving cycles, it is generally temporary in nature. However, if the fault persists, more complex action is required to clear Case Magnum fault codes.  

The Functions of the Jaltest Case IH Code Reader 

The Jaltest diagnostic software is optimized to clear fault codes across the complete range of Case IH farm machinery. Hence it can be used to troubleshoot issues and clear Case Magnum fault codes, Case IH Maxxum 125 fault codes, Case IH Puma fault codes, and other models. 

There are two primary functions that can be carried out with the Jaltest Case IH diagnostic tool. In the software menu you can either choose full system scans which is preventive maintenance or scans by symptoms when you have specific faults to deal with. 

Preventive maintenance or a full system scan must be carried out periodically to ensure that all systems and components of your agricultural machinery are working as they should and that any minor issue does not later become a major problem.

On the other hand, you have scanning by systems to detect and so away with specific fault codes. Here, you will be helped by technical information and data in real-time as well as detailed wiring diagrams of the faulty system or component. It will help you to understand the precise location of the fault for better and accurate corrective action that will not be less than what is offered by dealer servicing or certified engineers. 

For instance, our Jaltest Case IH code reader will inform you whether a particular fault code is related to the central computer, electronic module, climate HVAC, hydraulic system, engine, instrument cluster, power take-off, powertrain, and more. With this information, the software will quickly guide you through the whole troubleshooting process to get your farm machinery back on the job again. 

Our Jaltest fault codes clearance tool can perform a wide range of system checks. These include the cylinders test, high-pressure test, engine brake, Variable Geometry Turbocharger (VGT), throttle valve electric actuator for the exhaust engine brake, and more.

Moreover, the software is optimized for the Case IH Series Steiger, Magnum, Maxxum, Puma models, and more. Whether it is troubleshooting Case IH combine fault codes or for tractors, harvesters, sprayers, or any other type of agricultural equipment, you can be sure that the Jaltest software is optimized for it. 

Read more about the Jaltest Case IH equipment troubleshooting.

Case IH Engine Troubleshooting And Forced Regens

Among the engine fault codes for Case IH equipment that necessitate immediate action is cleaning out a Diesel Particulate Filter (DPF) for diesel engines. A DPF in diesel engines traps soot and other particulate matter that otherwise would have been released into the environment along with emission gasses from the engine. When the DPF gets clogged with soot accumulation, the performance of the engine drops substantially, and in severe cases, the equipment might even go into limp mode. 

This phenomenon of clogged DPF typically occurs in diesel engines that work for short durations as in agricultural machinery and not long haul as in interstate trucks and buses. The reason for this is that in short-haul operations, the temperature of the exhaust gasses does not arise enough to trigger passive regens that would burn the soot away.

When a fault code related to a clogged DPF pops up, our Jaltest Case IH software tool will guide you through the process of forced regens. Typically, the procedure is to run the engine at a high rev for around 40 minutes so that the exhaust gas temperatures rise to eliminate the soot and particulate matter buildup. Our diagnostic tool will guide you through the required engine rev, from High to Very High, and the time required based on the extent of the soot buildup. 

Forced regens can be carried out on all models of Case IH agriculture equipment such as the Case Steiger, Case Magnum 420, Case IH axial flow 9250/7150, Case Puma, and more.

Summing Up

The Jaltest Case IH code reader is a highly optimized software to keep your fleet of Case IH farm equipment in perfect running condition. Whether it is clearing Case Magnum fault codes, Case IH Maxxum 125 fault codes, Case IH Puma fault codes, or any other, we have you covered. 

Regardless of Case IH combine fault codes clearance or for tractors and harvesters, the only tool you will ever need is the Jaltest diagnostic software. You can be assured that your machinery will always be on the job and not suffer breakdowns during the peak harvesting season.
