Forced Regens With The Volvo Penta Scan Tool

For owners of vessels and equipment run on diesel engines, carrying out forced regens is not unusual. So, what is this essential activity that stops diesel engines from seizing up and going into limp mode?

It is very common for soot to buildup in the diesel particulate filter in diesel engines. It especially happens when engines do not run continuously but rather on a stop-go-stop mode such as excavators, dozers, and other construction and material handling equipment. When the condition of the filter is severe with soot, the engine stops working and the accumulated matter has to be cleared up.

Forced regens is an essential activity that is performed by Jaltest Volvo Penta engine diagnostic tools. The specific fault code surfaces when the passive regens are unable to clear the soot and external maintenance action is required to clear it. This is the role of forced regens in the Volvo Penta scanner, to identify the fault and clear it.

Typically, forced regens is done by running the engine continuously for about 40 minutes at a rev that is specified by the Jaltest Volvo Penta scanner tool. You will get the precise setting in the diagnostic menu ranging from High to Very High depending on the extent of soot buildup. Running the engine at a stretch raises the temperature of the exhaust gasses, thereby burning off the soot. Forced regens is a critical activity that must be periodically carried out on diesel-powered Volvo Penta engines.  

Technologically Advanced Functions of The Volvo Penta Scanner 

The Jaltest Volvo Penta scan tool provides detailed information about how to carry out corrective action and clear fault codes on Volvo Penta engines regardless of the make or model. An example will help readers to understand the fault clearance cycle better.

Cutting-edge Diagnostics With The Caterpillar Scanner & Diagnostic Tool

Before going further into the functioning of our Caterpillar scanner, a quick word on Caterpillar fault codes that are cleared by the Jaltest diagnostic tool.

Every modern piece of equipment today has an onboard computer that reflects the health of the machinery through certain alphanumeric codes. Any malfunction of a system or component corresponds to a fault code, usually alphanumeric, that is shown on the display screen below the dashboard on the driver’s side along with warning lights and alarm.

When our CAT diagnostic computer is connected to the onboard computer the specific fault code shows up here too along with the nature of the issue and the required rectification actions to be taken.

Our Caterpillar scanner provides great coverage of your construction equipment which include engines, hydraulics, transmissions, body computers, powertrains, instrument clusters, and several other systems. Once the fault code is identified, a host of functions, even the most complex ones like bi-directional activities and forced regens can be easily performed in-house to keep your equipment on the job.

What helps in diagnosing and clearing fault codes with our Caterpillar diagnostic tool is the detailed technical information, maintenance data, and wiring diagrams provided in the software.

Preventive and Corrective Troubleshooting With The Caterpillar Diagnostic Tool

The focus of the Jaltest Caterpillar digital diagnostic tool is to ensure that your equipment is always in top operating mode. There are two ways to ensure this, by taking preventive action or by solutions that are specific to symptoms and fault codes. Both processes are built into the CAT diagnostic computer.

The first is taking preventive measures to thwart any serious malfunction. Through our diagnostic menu, you can periodically undertake full system scans to identify any minor fault codes that might cause serious damage to your equipment if left unattended. These fault codes are temporary and typically go away after a few driving cycles. However, identifying them and clearing these fault codes prevent minor issues from becoming major problems.

The other use of the Caterpillar scanner is taking up scanning by symptoms. This is done when specific fault codes are shown and relevant action needs to be taken. Our maintenance tool will handhold you through the necessary action required to clear the fault code and bring your equipment back to working condition. The software will confirm that all critical parameters are working as per settings calibrated by you.

In short, it is always advisable to carry out full system scans on your Caterpillar construction equipment to pre-empt any malfunction, especially during peak operating seasons.

Caterpillar Engine Diagnostic Scanner

So long in this post, we have gone through the details of various systems of Caterpillar equipment and how the CAT diagnostic computer resolves the issues. Let us now check a key activity of a critical machinery of Caterpillar construction equipment which is the engine.

If you find the engine warning lights flashing, you must prioritize its solution over everything else. Whenever you find the engine of any Caterpillar construction equipment not sounding right or running rough, check the fault code and reach for the CAT engine diagnostic software to know what action must be taken to clear it.

It is always advisable to resolve the fault codes and not operate the equipment. However, in some cases where the equipment has to be moved to another location for better fault resolutions, make sure that any other warning lights of critical components like transmission and hydraulics are not on.

The biggest problem is that it is very difficult to say what is wrong with the engine without using our advanced Jaltest Caterpillar engine diagnostic scanner. It might be anything simple like a loose wire or something more complicated like soot buildup that requires activating force regens to prevent the equipment from going into limp mode.

It should be mentioned here that our Jaltest Caterpillar digital diagnostic tool performs force regens for Caterpillar equipment up to Level 2 though it goes much beyond that for other brands of construction equipment.

Now, what is forced regens that is taken care of with our CAT engine diagnostic software?

For diesel engines only, soot builds up in the diesel particulate filter, prevents the engine from performing at top capacity, and pushes the equipment towards limp mode. Forced regens carried out with our Jaltest software are the highest level of maintenance activity and are done when the usual passive regens cannot stop this soot accumulation in the DPF. When this happens, it shows up as a fault code in the Caterpillar scanner and must be cleared at the earliest.

Soot buildup usually occurs when the equipment does not run for long stretches at a time but carries out stop-go operations, common for construction equipment like tractors, dozers, and excavators. When force regens is required, our Caterpillar engine diagnostic scanner will guide you through the process. It will advise whether to go for High or Very High settings depending on the extent of soot buildup. 

Force regens is done by running the engine continuously for about 40 minutes at a specific rev as guided by the CAT engine diagnostic software. This leads to a rise in the temperature of the exhaust gasses that burn off the soot.

Another powerful maintenance action done by our engine diagnostic software is the code injector scanner. It helps to change the code injector in the Electronic Control Module (ECM) whenever an injector is installed or replaced.

Summing Up

The Jaltest Caterpillar scanner is a very user-friendly software that helps users navigate effortlessly through the diagnostic menu. Moreover, the tool can be configured and set up without the need to go through any elaborate processes. This gives our software over others in this niche.

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.
