All That You Need To Know About The Paccar Fault Code List

If you are looking for John Deere equipment, there will be a lot on your plate. Deere & Company, carrying on business as John Deere has a wide product range on offer.

On the one hand, you have heavy construction equipment like the John Deere 350GLC excavators, 850K dozers, 332G compact truck loaders, skid steers, motor graders, articulated trucks, and more. On the other, you have agricultural machinery such as tractors, combine harvesters, wheel loaders, skid steer loaders, and others. In between, you have forestry machinery, diesel engines, drivetrains like axles, gearboxes, transmissions, and even lawn care equipment.  

With so many different makes and models of equipment, John Deere is a leader in this niche globally and if you have one or a fleet of them you need the John Deere diagnostic software to keep them on the job.

Now, what is the function of the John Deere scan tool?

Every modern vehicle or equipment has an onboard computer that monitors the health of its various systems and components. These include engines, transmissions, hydraulics, HVAC, brake lights, body computers, and others. Whenever, a malfunction in the systems crops up, these are reflected as fault codes on the display panel of the onboard computer located below the dashboard on the driver’s side.

When you connect our Jaltest John Deere diagnostic scanner to the onboard port, the fault code along with the interpretation and the best solution to the problem will be shown on the software laptop. You can then start resolving the issue and get your equipment back on the job again at the earliest.

These fault codes may be of two types. One is temporary signifying a minor problem that goes away within a few driving cycles. The other is a more permanent one which persists over time and is usually quite complex like force regens. In this case, our John Deere diagnostic computer will handhold you through the solutions so that even a minor issue does not become a full-blown problem.

Using the John Deere Scan Tool

You can use the John Deere diagnostic software both as a preventive measure to forestall major faults from cropping up or as a maintenance tool to rectify any faults with the systems.

In the first instance, you may perform periodical full system scans to verify if all set parameters are performing as they should. This action will inform you of any minor issue so that you can take measures to prevent it from going out of control and requiring extensive repairs.

These include keeping a close tab on engines, hydraulic systems, instrument clusters, electronic control modules (ECMs), central computers, powertrains, and other critical components. Regular full-system scans help to keep your equipment on the job without a forced break.

The second way to use the John Deere diagnostic tool is to scan by symptoms or in other words to take corrective action whenever a fault code crops up. Such maintenance activities ensure the health of your equipment with dealer-level servicing and a host of functions can be carried out in this direction.

Among the key maintenance activities are performing force regens, code injectors, setting up flows and pressures on excavators, calibrating transmissions, and many others. Whatever might be the fault code, our John Deere scan tool has your back.

One of the critical functions and complex maintenance activities performed by our John Deere engine diagnostic software is force regens on diesel-powered engines, the bulk of which propels John Deere equipment of various models. Forced regens is done when soot accumulates in the diesel particulate filter and needs to be immediately cleared up to prevent the machinery from going into limp mode.

Forced regens is the highest level of maintenance task that must be done when passive regens have no effect in clearing the diesel particulate filter and it shows up as a fault code on the Jaltest John Deere diagnostic software. The soot buildup primarily occurs when the equipment does not run for long stretches at a time but performs stop-go operations as in excavators, dozers, tractors, agricultural equipment, and the like.

When the fault code shows up on the Jaltest John Deere engine diagnostic software, our maintenance tool will guide you on the activity required to clear the soot accumulation, varying from High to Very High depending on the extent of soot buildup. This will get your engine running again at peak operating efficiency.

Generally, when the issue of soot buildup is observed in our John Deere scan tool, it is resolved by running the engine continuously for around 40 minutes at a specific rev that is shown on our maintenance software. This leads to a rise in the temperature of the exhaust gasses which burns away the soot and frees up the engine.

Examples of Paccar Fault Code List

Here are a few examples of Paccar fault codes that will help you to understand better what is wrong with your vehicle whenever one such pops up on the onboard computer.

P3841 Fault Code Paccar: It indicates a form of trouble with the powertrain. You should fix it at the earliest because if the catalytic converter fails completely the truck will go into downtime. It is better to take the help of an experienced mechanic to clear this fault code.  

Paccar Fault Code P1495/P1496: When you see Paccar Fault Code P1495 or Paccar Fault Code 1496, it means that the engine protection has been enabled causing the EGR to be disabled and the system to go into preventative safety measures. As a result, passive/active DPF regeneration is disabled as well. The problem should be fixed within 10 hours to prevent it from going into EGR derate.

Paccar MX13 Fault Code P1515: This fault code shows up when the PCM detects that the commanded throttle blade position and the actual throttle position are not within a calibrated range of each other. If this occurs for a period of less than 1 second, the code sets and the traction control module is turned off. The PCM will not turn off the SES light until three driving cycles have been completed, signaling that the fault code has been cleared.

Paccar Fault Code P1517: This is a DEFOI (Diesel Exhaust Fluid Operator Inducement) code and indicates issues with emissions. This is often linked to problems connected with the codes P3822 or P3919. It will keep derating until the vehicle goes through verification cycle for the underlying code and the ECM decides that it passed the test.

Paccar SPN Fault Code List: The Suspect Parameter Numbers (SPN) code is a diagnostic fault code terminology found on some equipment that uses the J1939 CAN link. These were developed by the Society of Automotive Engineers and fault codes have been allotted to specific parameters, system circuits, or components that are typically associated with Diagnostic Trouble Codes (DTCs).

Paccar MX13 Fault Code List and Forced Regens

Among the most complex maintenance activities among Paccar fault code list is forced regens. It is exclusive to diesel-powered engines irrespective of the make or model. Forced regens is necessary when there is soot buildup in the diesel particulate filter to an extent where it shows up as a fault code and the vehicle goes into limp mode and the engine will seize up.

When it comes to clearing the DPF, forced regens is the highest level of maintenance activity when passive regens have no effect to clear the soot accumulation. Soot buildup occurs when a vehicle does not run for long stretches at a time but rather perform stop-go-stop work at quick intervals. Hence, forced regens are more required in dozers, excavators, agricultural and construction equipment.

When forced regens activity becomes necessary and is shown in the Paccar fault code list, our Jaltest software will guide you on how to bring the engine back into peak operating mode. The diagnostic menu decides on the level of forced regens, ranging from High to Very High depending on the extent of the soot buildup.

Typically, it means running the engine continuously for around 40 minutes at a rev specified by the maintenance tool. This causes increase in the temperature of the exhaust gasses which burns away the soot in the diesel particulate filter.

Summing Up

The Jaltest Paccar fault code list reader is a highly optimized software and maintenance tool for Paccar engines and its subsidiaries Kenworth and Peterbilt trucks. The user-friendly menu will handhold you through the required solutions for fault codes and ensure that your fleet is always on the road.

Kubota Engine Diagnostic Software and Forced Regens

One of the most complex activities that need to be carried out on diesel-powered Kubota engines is forced regens. This is an essential action that must be done to ensure that your Kubota diesel engine-powered equipment is always in peak operating mode.

Forced regens clear soot buildup in the diesel particulate filter. If left unattended the engine might seize up and the equipment will go into limp mode. Forced regens is the highest level of activity to clear the DPF and is required when passive regens fail to clear the soot accumulation.

Soot buildup is a very common occurrence when an engine is on a go-stop-go working as is common in dozers, excavators, and similar types of equipment, and does not run continuously for long stretches at a time. When the Kubota engine diagnostic software detects a fault code that is related to the soot in the DPF it will guide you on resolving the issue.

The power of the forced regens might be High to Very High, depending on the extent of soot in the DPF and this will be indicated in our maintenance tool. The method to clear the soot is by running the engine for around 40 minutes at an RPM that is indicated by the Kubota engine diagnostic tool. Running the engine continuously raises the temperature of the exhaust gasses and burns away the soot.

Simultaneously, along with the forced regens, you will also receive information about the regeneration of the SCR Catalytic Converter. Additionally, the Kubota code injector scanner also helps you to change the injector code in the Electronic Control Module (ECM) whenever an injector is replaced or installed.

Functioning Of The Hitachi Diagnostic Software

The Jaltest Hitachi scan tool offers options to check the health of the equipment and ensure that it is always in peak operating condition. There are two ways to go about it, preventive maintenance and troubleshooting by symptoms.

The first is diagnostics which are done at the first hint of trouble to ensure that a minor issue does not become a major full-blown problem at a later date leading to downtime. This is done by periodically scanning the equipment and figuring out whether there are any slight trouble that can lead to potential severe faults later.

Generally, such issues do not cause much trouble and are known as temporary fault codes. Suppose our Hitachi excavator diagnostic software identifies an issue with the transmission of an excavator. In case it persists and does not go away within a few driving cycles, more attention should be given to it since it might transform to a permanent fault code in the future.

Now, once a permanent fault code is detected, the same Hitachi excavator diagnostic tool will tell you what the fault code refers to it and suggest actions that will clear it. Our user-friendly software makes sure that your equipment is always on the job and any fault code is read and cleared at the earliest.

Deep Coverage With The Jaltest Hitachi Scan Tool

If you are operating or own a fleet of Hitachi construction equipment such as excavators, loaders, front shovels, and others regardless of the models, our Hitachi diagnostic tool is a must-have. You ensure that no malfunction goes unnoticed and you do not suffer because a small problem has escalated into an unmanageable permanent fault code leading to downtime and loss for your business.

Our Hitachi excavator diagnostic software offers excellent coverage of your construction equipment of this brand.

Additionally, you get access to our user-friendly dashboard which provides a wide range of technical data and information that allows you to carry out bi-directional functions and control engine operating speeds and oil flow adjustments through detailed live data monitoring wiring diagrams.  

No job is too difficult for the Hitachi scan tool as you get services that are typically offered at the dealer level.

Hitachi Excavator Diagnostic Tool And Force Regens

One of the most complex activities that is facilitated by our Hitachi diagnostic software is force regens. It becomes necessary for equipment that is powered by diesel engines, something that is very common on Hitachi excavator models. So, what is the Hitachi construction equipment fault code that requires forced regens to clear it?

Even though our Hitachi excavator diagnostic software is highly optimized to settle issues with transmissions, hydraulics, lights, and more, forced regens are a very critical activity that it does to keep the engine running without a break. Forced regens is carried out when there is a large soot buildup in the diesel particulate filter of diesel engines and the vehicle or equipment goes into limp mode in the most severe cases.

It typically happens when the usual passive regens cannot clear the soot in the DPF and forced regens activity must be done. It is a phenomenon that is typically seen in engines that are not run on long stretches but have stop-go actions continuously. Forced regens is the highest form of DPF regeneration.

Our Hitachi diagnostic tool through the onboard computer will warn you if soot has accumulated in the DPF and requires clearing up. The software will guide you through the power of force regens required from High to Very High. To perform forced regens, the engine should be running for about 40 minutes at an RPM to be calculated by the maintenance tool. This raises the temperature of the exhaust gasses which ultimately burn the soot off the diesel particulate filter.

Hitachi Excavator Diagnostic Software – Clearing Fault Codes

We have seen in this post how the Hitachi diagnostic tool reads and clears any malfunction with your equipment as shown by fault codes in the onboard computer. While fault codes are not standardized, they are common among different models of equipment. For instance, the Hitachi excavator diagnostic tool analyses the fault codes of most series of Hitachi excavator issues and provides cutting-edge solutions.

Here are some fault codes of Hitachi excavators and what that means for you.   

• 11100-2 engine speed is abnormal
• 11101-3 engine speed control knob sensor high pressure abnormal
• 11200-3 Pump 1 oil pressure sensor high pressure abnormal
• 11200-4 Pump 1 Oil pressure sensor low pressure abnormality
• 11301-3 Rotary pilot pressure sensor high pressure abnormality
• 11302-3 Boom lifting pilot pressure sensor high pressure abnormality
• 11302-4 Boom lift pilot pressure sensor low pressure abnormality
• 11304-4 Walking pilot pressure sensor low pressure abnormality
• 11400-2 Pump 2 Maximum Flow Limit Control Solenoid Valve Current Feedback Abnormal
• 11401-2 Torque control solenoid valve current feedback abnormal

Now let us check an example of the full process that our Hitachi excavator diagnostic software will take you through. 

Fault code: 11301-3

• Fault problem: high pressure abnormality of rotary pilot pressure sensor
• Fault reason: voltage 4.75V or above
• Affected control: (1) Stick regeneration control (2) Attachment flow control (3) Slewing alarm control
• Symptoms of machine operation when the fault occurs: (1) Stick retracting and swiveling combined operation stick speed is slow (2) If the machine is equipped with a swing alarm and when the swing alarm is active, the swing alarm continues to sound
• Remarks: (1) Check the wiring harness (2) Replace the rotary pilot pressure sensor

As can be seen, our Hitachi diagnostic tool takes you through the full gamut of fault clearance. It starts from the time a fault code is detected on the onboard computer and reflected in the software after our laptop is linked to the equipment, right up to the time the fault is cleared. 

Live Data Monitoring and Technical Information From the Hitachi Scan Tool

Our Hitachi diagnostic software for construction equipment provides deep coverage of all critical parts and components including engines, hydraulics, transmissions, body computers, and more. The goal is to ensure that temporary faults do not become major permanent ones and arrive at resolutions that always keep your equipment running at optimum efficiency.

Take the instance of Isuzu and Cummins engines that power Hitachi equipment. In case there is soot accumulation in the diesel particulate filter of the engines, the software warns you that necessary action is required to prevent disruption of work. All parameters of the engines are before you on the diagnostic menu of the Cummins or Isuzu engine code reader and you can take any corrective action and dealer-level servicing without having to fall back on the manuals.

Our software is flexible enough to allow you to set metrics within which you want your equipment to function. These might be engine operating speed, pressure accumulator, oil flow adjustment, and any other that you want to adjust to maximize the use of your equipment. With Cummins and Isuzu engines, you can even set up flows and pressures on excavators, calibrate transmissions in wheel loaders, and other dealer-level services.
