Expert Tips For Caterpillar Construction Equipment Fault Codes Troubleshooting

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 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. 

Summing Up

The Jaltest OHW diagnostic software is a highly optimized tool to keep your fleet of heavy-duty trucks and construction equipment on the job without breakdowns. It is the ideal maintenance tool to troubleshoot problems with your equipment as it offers cutting-edge solutions. You are guided through a user-friendly menu with live information and detailed wiring diagrams to make your task simpler.  

We also offer three upgrades to our Jaltest off highway diagnostic software every year to keep abreast of the technological improvements implemented by leading brands to their equipment. By this step alone, we ensure that Jaltest Off Highway never becomes obsolete. 

Finally, what makes our Jaltest software a leader in this niche is its ease of setting up. Unlike our competitors, there are no elaborate configuration and set up processes to follow. Simply download our software to your laptop, plug it into the onboard computer of your equipment and you are ready for fault code diagnosis and clearance.

The Jaltest Allison transmission diagnostic tool is cutting-edge software designed to identify and clear any faults with the transmission.

Studies have shown that vehicles with Allison transmissions save over 5% in fuel costs per year over similar types of vehicles with non-Allison transmissions. 

Finally, Allison transmissions offer superior performance as the automatic transmission system makes use of the engine’s horsepower and torque to give ride comfort and greater maneuverability.  

Despite these advantages of Allison transmissions, if you have a fleet of vehicles with this transmission, you must also have Allison transmission diagnostic software to back you up. The reason is explained in this post which explores the cutting-edge Allison transmission diagnostic tool.  

The Functioning Of the Jaltest Allison Transmission Diagnostic Scanner

The main feature of the Jaltest Allison diagnostic software is to read fault codes to identify a malfunction and then interpret it and provide advanced rectification solutions. Once a fault is detected the tool guides you on specific solutions that are at par with what is offered by certified engineers at the dealer level.  

Now, let us check what fault codes are to help understand the functioning of the Jaltest Allison diagnostic scanner. 

Fault codes, also called Diagnostic Trouble Codes (DTC) show any malfunction with the systems and components of vehicles, construction equipment, and more. When the onboard computer, a mandated addition to modern vehicles identifies a fault, it is displayed on the screen of the onboard computer, usually placed below the dashboard on the driver’s side.

The fault code, generally in alpha-numeric format covers all systems and components ranging from the engines, transmissions, hydraulics, brake lights, fluid temperatures, transmission sensors, control system functionality, and others. 

Given here are some examples of Allison transmission codes, how they show up on the display screen, and their interpretation by the Jaltest Allison transmission diagnostic tool.

• P0218: Transmission Over Temperature: This code usually means the transmission is overheating. This can occur if the transmission fluid is low, the lines are restricted or the cooling fan is not operating. 
• P0613: Transmission Control Module (TCM): A poor electrical connection or shorted TCM harness can cause this code to be generated. 
• P0614: ECM/TCM Incompatible: The TCM and ECM (Engine Control Unit) are not communicating. This code usually occurs when either the TCM or ECM has been replaced, and the replacement part is not configured to work with the existing part.
• P0700: Transmission Control System Malfunction: The TCM is responsible for relaying fault codes that turn on the vehicle's check engine light. 
• P0706: Transmission Range Sensor Circuit Range/Performance: The transmission range sensor conveys information about the gear the vehicle is into the TCM and powertrain control module (PCM). 

After getting a grip on the fault codes for Allison transmission that show up on the Allison transmission diagnostic tool, let us check the connection between the two.

The Allison diagnostic tool is an advanced tool that diagnoses faults in Allison transmissions, allowing certified engineers and technicians to read and clear fault codes guided by the Jaltest software.

For owners of Cummins-engine-powered equipment and machinery, it is essential to have Cummins diagnostic software to ensure that their project or work is not impaired and they are always on the job.

This post will go into the various aspects of the Cummins diagnostic tool and fault code clearance so that your machinery is always in peak performance mode. 

The Function Of The Cummins Diagnostic Software

To understand the functioning of the Jaltest Cummins diagnostic tool, it is necessary to first know what fault codes are since they are resolved with the help of the software.

Every modern vehicle, construction, or material handling equipment has an onboard computer called the Electronic Control Unit (ECU). It indicates the health of the equipment and any malfunction is displayed as fault codes in alpha-numeric format on the display that is generally positioned below the dashboard on the driver’s side. 

These fault codes might be minor and temporary and go away within a few driving cycles or more permanent requiring expert rectification solutions. This is where the Cummins engine diagnostic tool has a major role to play in keeping your fleet on the job. It tracks the fault code, interprets what the issue is all about, and offers solutions that prevent any minor problem from becoming a full-blown one.

If the fault code indicates the presence of a serious problem with the need for an overhaul of systems or components, our Jaltest Cummins diagnostic tool makes the process easy and seamless. Simply connect the Jaltest Cummins diagnostic computer to the onboard computer of the vehicle and it will help you identify the fault and handhold you through the process of clearing it. 

The Jaltest Cummins diagnostic software is optimized to describe the fault in detail and suggest solutions that are no less than dealer-level ones from certified engineers. The software offers detailed wiring diagrams of the systems so that you can know the precise location of the fault and what are the parts and components that are affected.

How To Get The Most Out Of Your Cummins Diagnostic Computer

The Jaltest Cummins diagnostic software is a very intuitive and user-friendly maintenance tool that ensures that your Cummins engine runs always at peak operating efficiency. You can carry out both preventive maintenance as well as clearing fault codes whenever they arise. 

Let us check out these critical functions in some detail.

The first is preventive maintenance to check the health of the engine even though there is no fault code signal apparent on the display screen of the onboard computer. All that you have to do is connect the Cummins engine diagnostic tool to the ECU and carry out full system scans at pre-determined intervals. 

There are two benefits here. One is to check that all systems and components are working as they should and that the engine is performing optimally. The other is to identify any minor issue and work on it before it blows up into a major problem leading to prolonged downtime and delayed projects. Preventive maintenance is a very crucial activity to prevent and solve any issue at its root. It checks whole systems and components such as engines, transmissions, hydraulics, brake lights, HVAC systems, and more. 

The second is clearing fault codes whenever they are shown on the display screen of the onboard computer. At this stage, the Jaltest Cummins diagnostic tool must be connected to the ECY, and a scan carried out as per the symptoms and the fault code. 

The software will read the fault code and carry out rectification solutions to clear it. You will be prompted to enter the model of the Cummins engine since fault codes are not standardized across all makes and models of equipment and engines. The tool will guide you through the process of bringing your engine to perform at optimum power. 

The inbuilt component replacement guide is a very critical feature offered in the Jaltest software. If a component malfunctions, the software will inform you whether it needs to be replaced or repaired. If replacement is necessary, the tool will help you to navigate how it should be done. 

While fault-clearing activity is important, no less is preventive maintenance as it pre-empts any major fault from developing.

• 121 (Yellow): Engine Speed/Position Sensor Circuit - lost one of two signals from the magnetic pickup sensor
• 122 (Yellow): Intake Manifold Pressure Sensor #1 Circuit - shorted high
• 123 (Yellow): Intake Manifold Pressure Sensor 

Our Jaltest Cummins diagnostic tool not only detects the fault codes but also navigates users through rectification processes that bring the equipment to top operating mode. 

Cummins Diesel Diagnostic Software And Forced Regens

Forced regens is an activity that is exclusive to diesel engines. It is required when the Cummins diesel diagnostic software detects high soot accumulation in the Diesel Particulate Filter because passive regens have been unable to clear it. In severe cases of soot buildup, the engine might even seize up and go into limp mode. 

Soot buildup occurs when the engine has a stop-go-stop routine that is generally seen in construction equipment such as dozers and excavators and not in long-haul trucks and buses. The fault code for soot accumulation in DPF is SPN 3712 which means that the ECM has limited engine power to facilitate a forced regen cycle. This code also shows up in cases of clogged DPF, faulty DPF sensors, problems with exhaust gas recirculation (EGR), or low-DEF levels. 

After the Jaltest Cummins diagnostic software identifies the issue, it suggests optimized solutions that are generally to run the engine on high rev for around 40 minutes. The rise in exhaust gas temperature burns away the built-up soot. Our software will also guide you on clearing related problems such as replacing faulty sensors, cleaning the DPF, or addressing troubles with the EGR system.
