Cummins Diesel Engine Fault Codes 

If you are an owner of vehicles or equipment powered by Cummins engines, you must have come up against Cummins fault codes in the form of alphanumeric messages on the onboard computer display, typically tucked away below the dashboard on the driver’s side.

Cummins engine fault codes are alerts to warn you that something is not right with the engine and quick action is required. The fault codes may be a sign of a simple error or a complex one that may require downtime and stoppage of work.

Let us take a couple of examples to explain the concept of Cummins fault code better. 

• Cummins engine fault code 1117: This fault code indicates a lost power supply with the ignition on. Possible causes are a faulty battery, damaged wiring harness, faulty ECM, or corroded or loose battery connections. 
• Cummins engine fault code 1569: The explanation of this Cummins fault code is “Engine Protection Torque Derate” which in simple terms means the engine is reducing power due to a detected issue. It is related to problems that affect the engine performance such as with the aftertreatment sensors or actuators.  

These codes will show up when you connect our Jaltest Cummins engine code reader to the onboard computer. The software will then guide you through all that is required to be done to get your vehicle or equipment back on the job at the earliest. 

Know more about the types and models of Cummins engines

If you consider Cummins engine fault codes, there are two possibilities here. 

The first is the pending or temporary Cummins engine trouble codes that indicate early signs of a problem which is at the minor stage and if left unattended, can blow up into a major issue necessitating downtime. Use the Jaltest software to track the trouble and clear it. Such temporary fault codes typically disappear within a few driving cycles.

The second is more serious issues where a great deal of overhaul is required. Here, our Jaltest Cummins engine code reader is very useful and makes the rectification process smoother. The Jaltest scanner is a user-friendly device that connects to the onboard computer of the vehicle. Once the software laptop is plugged in, turn on the engine, and it will read the Cummins fault code and zero in on the problem.

The Jaltest Cummins engine fault code list helps you pinpoint the exact issue with detailed descriptions of the fault. It will handhold you through the solution, backed by detailed wiring diagrams that assist you in finding the location of the fault, the precise nature of the fault, and what is required to be done. You can then carry out the fault-clearing solutions confidently with the Jaltest Cummins engine code reader.  

The Jaltest software performs Cummins engine diagnostics and shows all engine electronic information on the laptop screen. Working with Jaltest is easy as it guides you through step-by-step diagnostics, schematic diagrams, and built-in engine drawings. Hence, troubleshooting time is reduced, and faulty diagnostics and resolution procedures are done away with as you get wiring and sensor location diagrams, and can adjust parameters to quickly and easily review and clear fault information. 

A quick mention should be made here of a very specialized tool, the Jaltest Cummins ISX code reader. The Cummins ISX engine is one of the top-range Cummins heavy-duty diesel engines and the Jaltest ISX code reader is specifically designed to read and interpret this Cummins fault code. It directly retrieves diagnostic information like error codes and live data and helps you to identify and troubleshoot issues within the engine systems. 

The main function of the Cummins ISX code reader is to display live engine data such as fuel pressure and coolant temperature and clear Cummins diesel engine fault codes. It also provides guidance on potential causes for the detected issues, making troubleshooting simple and an on-premises activity.

Preventive and Maintenance Activity With Jaltest Cummins Code Reader

The Jaltest Cummins fault code reader is a very intuitive and user-friendly Cummins diagnostic tool that ensures that all your equipment and vehicles powered by Cummins engines are always in peak working condition. With the software, you can carry out preventive maintenance to ensure that the Cummins engines are always on the job or quickly clear fault codes whenever they arise. 

These two features are often termed preventive maintenance and clearing fault codes, both of which will be explained individually now in some detail.  

A key feature in the Cummins fault code reader is full-system scans as a component of preventive maintenance that is performed at periodic intervals. In this mode, you scan all the systems starting from the engine and going on to the hydraulics, transmissions, brakes, lights, and more. Any minor issue here is quickly resolved before it takes on a bigger form that can lead to downtime and stoppage of work, often at crucial times of projects. 

On the other hand, you have the fault-clearing work with the Cummins fault code reader. Whenever a fault arises and the code is displayed on the onboard computer screen, connect the Jaltest software laptop to it and get to the bottom of the issue. Once the code is identified per the model and make of the Cummins engine-powered vehicle, you will be guided on fault-clearing procedures. 

It is important to note here that preventive maintenance with the Jaltest diagnostic tool will keep your equipment on the job without a break. 

Cummins Engine Trouble Codes and Forced Regens

One of the faults exclusive to diesel engines is soot accumulation in the Diesel Particulate Filter (DPF). In severe cases, it will turn out to be a major problem and the engine might seize up too. This soot buildup normally occurs when passive regens are incapable of removing the soot from the DPF and forced regens must be taken up. Typically, this condition takes place when the vehicle is on a stop-and-go workload as in excavators and dozers, and not much in long-haul vehicles such as trucks and buses. 

When such a situation arises, our Jaltest Cummins engine fault code list will show fault code SPN 3712. It means that there is engine power derate due to DPF regeneration and that the ECM has limited engine power to facilitate a forced regen cycle. The most likely causes for soot buildup in the diesel particulate filter are clogged DPF, faulty DPF sensors, problems with exhaust gas recirculation (EGR), or low DEF levels. 

One way of addressing this Cummins fault code is to use the Jaltest software tool to identify the exact fault code and its associated parameters. Inspect the DPF for excessive soot buildup, potential damage, or sensor malfunction. 

Once any of these aspects are confirmed through the Jaltest Cummins engine code reader, the simplest solution is to run the engine on a high rev for around 40 minutes. The rise in the temperature of the exhaust gasses will burn away the soot accumulation. Next, the underlying issues for this state of the Cummins engine must be solved. These include replacing faulty sensors, cleaning the DPF, or addressing issues with the EGR system. 

Summing Up

The Jaltest Cummins engine code reader is optimized for your Cummins engine-powered machine or vehicle regardless of its make or model. You get expert guidance to clear any fault codes quickly so that any minor issue does not become a major one and you get dealer-level servicing on your premises.

It is now mandated by law that all modern vehicles and equipment have an onboard computer that tracks and manages their health so that they always maintain optimum running mode. Any malfunction is instantly notified on the display screen of the computer, typically in alpha-numeric mode known as fault codes so that rectification solutions may be implemented to get the vehicle or equipment back on the job as fast as possible.

This is where the Jaltest diagnostic software comes into the picture. When you connect the Jaltest software laptop to the onboard computer, the fault code corresponding to the problem shows up along with the interpretation of the code and the solutions required to get the vehicle back on the road.

The benefit of this Jaltest scan tool is that highly optimized solutions are provided for all systems and components. You get live maintenance and information about the state of the equipment along with detailed wiring diagrams to know the precise location of the fault. Hence, from the fault code, you can know whether the problem is with the engine, transmission, hydraulics, brakes, lights, body computer, or any other.

Almost all types of vehicles are covered by our Jaltest diagnostic software. We offer Jaltest marine software, Jaltest truck and commercial vehicle diagnostic tool, Jaltest off-highway software, and many others. As examples, a few of them will be studied in detail in this post.

The Jaltest diagnostic tool has two very important options, one is for preventive maintenance and the other is rectification of issues, from minor ones, setting them right before they become full-blown problems.

In the first instance, you can carry out periodic full system scans to check the state of your equipment. Any minor issue will be detected and can immediately be set right through the software. This procedure ensures that your equipment is always in top working condition, and if any temporary fault codes are seen, they are usually cleared within a few driving cycles.

In the second instance, fault rectification is done when there is a specific issue to contend with in any system of the equipment. Our Jaltest diagnostic software will handhold you through the full process of solving the problem, offering dealer-level resolutions. You can get your equipment working again on the premises without having to call in certified engineers or go through bulky manuals.

A quick word on the Cojali Jaltest diagnostic software before moving forward. Cojali S.L. is based in Campo de Criptana and is a Spanish developer of advanced diagnostic solutions for commercial vehicles, off-highway equipment, material handling equipment, marine vessels, and agricultural equipment such as tractors.

• Configuring measurement groups in the data recorder function.

The Jaltest diagnostic software for trucks is a comprehensive maintenance tool that is effective for trucks, ranging from heavy-duty to semi-trucks, and light commercial vehicles.

Force regens

While on the Jaltest truck diagnostic tool, one of the critical functions of diagnosis and fault rectification is forced regens exclusively for diesel-powered vehicles and equipment. This function is applicable not only for trucks and commercial vehicles but also for construction equipment such as excavators, dozers, and agricultural vehicles like tractors. The need for force regens rises only when the equipment runs on diesel-powered engines.

Forced regens are necessary when soot accumulates in the diesel particulate filter and passive regens are not enough to clear this soot buildup. This might lead to the engine seizing up or the vehicle going into limp mode, based on the severity of the accumulation. When the fault code for soot buildup shows on the Jaltest CV diagnostic tool or Jaltest AGV maintenance tool, the software will guide you through the critical procedure of forced regens.

To clear the soot buildup, the engine is run for around 40 minutes on High or Very High rev as determined by the software. The high temperature of the exhaust gasses burns off the soot and the equipment is back on the job at the earliest.

Jaltest Diagnostic Software and Calibration and Parameter Settings

Another advanced function of our Jaltest software is calibration and parameter setting. To understand these functions better, let us follow an example of hydraulic systems of heavy-duty construction equipment such as excavators. All excavators have factory settings that are standardized and work within normal metrics in typical terrains.

However, if your equipment works in very challenging conditions, you must recalibrate hydraulics settings with an advanced tool like the Jaltest diagnostic software to get maximum productivity from your equipment. Calibration and hydraulics parameter settings require users to reset values to control response, pressure, and flow rate. Our software will help you to tweak and modify the functions of the hydraulic systems to maintain high operating efficiency regardless of the condition that the equipment is functioning in.

Calibrating key systems like hydraulics typically involves working on specialized components like attachment controls, position sensors, and solenoid valves. This can be done effortlessly by our Jaltest scan tool. After you connect the Jaltest software to the onboard computer of the equipment, you will be prompted to enter the make and model of your equipment along with the specific calibration activity you want to take up.

If you have one or more John Deere equipment in your fleet, you need the Jaltest John Deere engine code reader to track and monitor their health and ensure that they are always on the job without downtime.

The John Deere Engine Fault Codes List And How Does It Work 

It is now required by law for every modern vehicle or equipment to have an onboard computer to know about their state on various metrics. These include hydraulics, brake lights, body computers, transmissions, and most importantly, engines. When a malfunction occurs, it is shown as a fault code, typically in alpha-numeric form, on the display panel of the onboard computer tucked away below the dashboard on the driver’s side.

Based on the identification of the code and the corresponding problem, resolutions can be initiated to bring the equipment back on the job. This is done with our Jaltest John Deere trouble codes reader and software which needs to be connected to the onboard computer. Backed by live technical and maintenance data, you can resolve the issues at a level that is no less than the dealer level.

Now, what are trouble codes also known as John Deere flash codes?

These codes are displayed on the onboard computer as a flashing light sequence indicating a fault within the systems or components of the machine or equipment. When you connect the Jaltest John Deere engine code reader to the onboard computer, the John Deere flash codes will be reflected on the software laptop too. From here, you will be guided on the most optimized solutions to bring your equipment back on the job.

Take the example of John Deere excavator trouble codes. As with other types of John Deere equipment, these codes are of two types.

One is the temporary Diagnostic Trouble Code (DTC) or flash code that requires simple solutions and generally is cleared within a few driving cycles before a minor issue becomes a full-blown problem.

The other type is more permanent in nature and needs complex resolutions to clear. An example is Flash Code ECU 001008.18 which indicates low oil pressure related to the engine control unit. Another example is soot accumulation in the diesel particulate filter of diesel engines.

A quick word about John Deere SPN code is relevant in this context. SPN is short for Suspect Parameter Numbers and represents fault codes that indicate that something is wrong with the vehicle or equipment. SPN codes specify the type of vehicle and where it was issued, provide important information about specific malfunctions, and help to quickly and seamlessly resolve issues with the equipment.

An example of John Deere SPN codes is SPN 157 which informs that fuel pressure is low or rail pressure sensor voltage is out of range. SPN codes are applicable only in John Deere equipment that uses a J1939 CAN data link.

In every instance, our Jaltest John Deere engine live monitoring tool will guide and handhold you through the most optimized solutions so that your equipment is back on the job at the earliest.

John Deere Engine Live Monitoring Features 

There are a host of functions that can be carried out with the John Deere Engine Live Monitoring features that help you identify any problem before it can adversely impact the performance of the engine. You get key insights into equipment performance parameters that enhance productivity and ensure that your machine performs optimally under the right conditions.

With John Deere engine live monitoring, you can track live engine RPM and Load in real time on the “Right Now” tab of the Operations Center Mobile to know the current working conditions. Similarly, the “Today” tab provides daily updates on equipment utilization including fuel consumption and utilization hours. By monitoring fuel consumption, you can be sure that your equipment will never go into “Empty” mode at peak operating times.

Let us take an example of John Deere excavator engine live monitoring and what you can do with this feature.

The remote monitoring capabilities are as follows.

• Monitor the current engine load and RPM live and in real-time.
• Track the volume of fuel in your equipment and fill it up before it grinds to a halt.
• Know where the equipment is located and how many hours of fuel is remaining in it.
• Check the utilization of the equipment and for how long is it idling, working, or transporting. This is important to know the level of your return on capital investment.

The diagnostic capabilities are as follows.

• Remote diagnostics and programming by connecting remotely with the Jaltest John Deere engine code reader. It allows you to read and clear John Deere trouble codes and record performance data so that engine parameter settings can be carried out whenever needed for best performance and productivity.
• Quick alerts provided by technologically advanced algorithms that analyze machine data to recognize potential flash codes before they become major issues leading to downtime.
• Updates about the entire operations including field and machine updates are provided around the clock.
• John Deere trouble codes are flashed on the diagnostic software that you can check from our Jaltest John Deere engine fault codes list. Once you get information about possible engine or other system issues, you can carry out full system scans to locate the malfunction and set it right.

When you undertake a John Deere engine system check, you can either opt for periodical full system scans or scan by symptoms when a trouble code pops up. In the first instance, you scan all the systems, starting from the engines and going to transmission, hydraulics, and more. Any small issue will be identified and you can immediately resolve the issue without having to go through lengthy procedures.

On the other hand, when you scan by specific systems, our John Deere engine code reader will first prompt you to provide a series of information ranging from the make and model of the equipment to the nature of the fault before advising on how to set it right.

Setting John Deere Engine Parameters

Taking up John Deere engine parameter setting is not a complex activity once you use the Jaltest engine code reader software. Engine parameter settings maximize productivity and performance and you get the most out of your equipment. The parameters set depend on the work being done, the condition of the terrain, and several other factors. For example, dozers are used in various challenging terrains and hence, the John Deere dozer engine parameter setting will take this factor into account.

The model of the equipment and the job on hand also play a major role in determining the parameters that include engine power limits, maximum engine speeds, and other engine metrics.

The John Deere engine parameter setting is done by connecting the Jaltest John Deere engine fault codes list software to the onboard computer of the equipment and adjusting engine parameters. You need to access the software and navigate to the “engine” option in the menu. Now set the various engine parameters that will optimize the performance of the equipment from the drop-down menu.

John Deere Trouble Codes And Forced Regens

Forced regen is one of the most critical activities on the John Deere engine fault codes list and a complex one too. Forced regens become essential when there is soot buildup in the diesel particulate filter of a diesel-powered engine and passive regens are unable to clear the soot. Depending on the severity of the soot accumulation, it is not uncommon for equipment to seize up and go into limp mode.

When such a trouble code shows up on the Jaltest John Deere engine code reader, the software will take steps to clear the soot through forced regens. Typically, it means running the engine for around 40 minutes at a rev as specified in the software ranging from High to Very High based on the extent of soot accumulation.

The rise in temperature of the exhaust gas due to the constant running at a high rev burns off the collected soot in the diesel particulate filter and frees up the engine. This fault happens in diesel-powered engines that have stop-go-stop driving cycles like dozers and excavators and not long-haul buses and trucks that run for extended periods.

Summing Up

The Jaltest Jogn Deere engine code reader is optimized for your John Deere equipment regardless of its make or use. Our user-friendly software guides you on clearing John Deere trouble codes so that your equipment gets dealer-level servicing on your premises and downtime, if any, is at a minimum.

Further, our software has an edge over others in this niche because it is very user-friendly. Unlike others, you do not have to go through elaborate set up and configuration processes when installing the software on your laptop. It is an easy plug-and-play job and your tool is ready for fault code diagnosis within no time.

Finally, we provide three updates to the software every year to keep abreast of technological innovations to John Deere equipment. This is to ensure that our maintenance tool does not become obsolete.

The Hitachi Construction Company Ltd is a global leader in manufacturing heavy equipment, primarily in the construction niche. The first Japanese mechanical excavator was designed and manufactured in 1970 by Hitachi and today, the company has set benchmarks in excavator productivity and reliability.

This post will go into the main areas of Hitachi excavator troubleshooting and Hitachi excavator fault codes, with a special focus on Hitachi excavator hydraulic problems.

If you have a fleet of Hitachi excavator construction equipment, it is essential that you have the Jaltest Hitachi excavator fault code list software to clear your equipment of any malfunction. When any fault codes pop up in the onboard computer, simply connect our software to it and get detailed technical and maintenance information in real time about the health of the excavator and where the fault is located.

You will also be guided on how to clear the fault codes so that your excavator is back on the job without prolonged downtime. The fault code may also be termed as Hitachi excavator trouble code (DTC or Diagnostic Trouble Code).

Now, let us understand the fundamentals of hydraulic systems before going further into the intricacies of Hitachi excavator hydraulic calibration. The hydraulics of an excavator are powered by fluid driven by various pumps. The hydraulic systems generate and transmit power through pressurized oil or hydraulic fluid and move the equipment by converting mechanical power into hydraulic power.

The flow and pressure of hydraulic pumps are sourced from fluid stored in a reservoir which moves through the hydraulic network, thereby operating cylinders, motors, and other hydraulic devices. So, what is Hitachi hydraulic system calibration?

Any hydraulic system is factory-calibrated to offer the best operating productivity under standard working conditions. However, when the set calibration goes out of parameters, the performance of the equipment will be affected giving rise to fault codes because of malfunctioning components and systems. It is here that the Jaltest Hitachi excavator troubleshooting tool will help you calibrate the hydraulic systems on the premises so that your equipment is back on the job in peak performance mode.

Hitachi Excavator Troubleshooting and Forced Regens

One of the most complex activities for troubleshooting Hitachi excavators is force regens on diesel-powered engines that are carried out to perfection by our Jaltest Hitachi construction equipment diagnostic software. Excavators are typically run on diesel power and hence, force regens is very necessary to keep the excavators on the job.

Force regens become essential when soot builds up in the diesel particulate filter and passive regens are unable to clear it. This leads to the engine seizing up and the excavator going into limp mode. Soot accumulation is very common in diesel engines that work in short spells such as excavators and do not run continuously like long-haul trucks and buses.

Through the Hitachi excavator fault codes list you will know if there is soot buildup and forced regen is required. When the specific fault code shows on the software laptop, you will be guided on how best to clear the soot. You will be given High to Very High choices depending on the extent of soot in the diesel particulate filter.

The software will take you through the forced regens activity. It typically requires the engine of the excavator to be run continuously for around 40 minutes at a specific engine rev as noted by the software. The rise in temperature of the exhaust gas burns off the soot and the excavator is soon back in working condition.

Summing Up

Whether it is Hitachi excavator troubleshooting or performing Hitachi hydraulic system calibration, depend on the Jaltest Hitachi excavator software to deliver optimized results. Our intuitive maintenance tool handholds you through the Hitachi excavator fault code list, reads and interprets it, and finally offers advanced cutting-edge and optimized solutions to clear the fault codes.

What helps is that you get maintenance and technical data in real-time as well as deep coverage of wiring diagrams of all systems and components of excavators. By following the diagrams, you can precisely locate the fault and implement resolutions that are no less than dealer-level servicing.

What sets our software apart from others in this niche is the ease of setting it up in the software laptop. There is no elaborate set up or configuration process to follow. Simply download the software, plug it into the onboard control port of the excavator and you are ready to diagnose fault codes.

Finally, we provide three updates to our software every year. This is to keep abreast of any technological innovations implemented in Hitachi excavators and to ensure that the our Hitachi excavator troubleshooting tool never becomes obsolete.
