It is said that the wealth of a nation is often measured by construction activities and infrastructure development. This is the backbone that a country depends on for overall growth and progress. It is therefore not surprising that heavy-duty trucks and construction equipment in various categories are often the preferred source for capital investment.

However, it is not sufficient to have these vehicles and equipment only, it is more important that they are on the job without a break to avoid loss and poor returns on investment. Hence, for owners of heavy-duty construction trucks and heavy equipment, it is essential that they have a heavy equipment diagnostic tool for the maintenance and upkeep of their fleet. There is no better maintenance software than the Jaltest diagnostic tool to keep your equipment on the job.
Fault Codes And The Function Of The Off-Highway Diagnostic Tool
Before going into the various aspects of the Jaltest heavy equipment diagnostic tool, it is necessary to understand the concept of fault codes. This is because clearing the fault codes is the primary work of any heavy-duty diagnostic computer.
It is now mandated by law that all modern vehicles including off-highway, construction, and materials handling equipment have a central onboard computer. Its function is to track the health of the vehicle and warn users of any malfunction in the systems and components through fault codes, also known as Diagnostic Trouble Codes (DTCs). There are hundreds of fault codes that are specific to the make, model, and particular problem in the equipment.

When a fault code pops up as a warning light on the display panel, generally tucked away below the dashboard on the driver’s side, an optimized diagnostic scanner must be used for fault resolution. The issue might be related to the engine, hydraulics, transmission, or any other system or component.
In the case of vehicles, use the Jaltest diagnostic computer for heavy-duty trucks to bring the vehicle back on the road as soon as possible by clearing the fault codes, which will be either a temporary or a permanent one.
In the case of a temporary fault code detected during a full system scan by the Jaltest heavy-duty diagnostic computer, minor adjustments are usually required and the fault code is cleared within a few driving cycles. However, if the fault persists, our Jaltest heavy equipment diagnostic tool will guide you through specific rectification activities that are no less than dealer-level servicing.
Heavy-Duty Truck Diagnostic Scanner
The Jaltest heavy truck diagnostic software stands tall among its competitors in this niche mainly because of its versatile features. The maintenance tool covers almost all major truck manufacturers including Kenworth, Paccar, Mack, Freightliner, Allison, Peterbilt, Cummins, Detroit, Bendix Western Star, Volvo, International and more.

Hence, if you have a mixed fleet of heavy-duty trucks, one software will do the job of keeping all the trucks in peak performance mode. It performs fault rectification activities of systems and components including engines, brakes, hydraulics, transmissions, truck bodies, and more. It also provides advanced cutting-edge maintenance data that can be tracked through live data monitoring to clear fault codes.
Our diagnostic computer for heavy trucks offers deep coverage and detailed technical information about the complete fault rectification process.

Heavy Truck Diagnostic Software –Cummins and Paccar Engines
When you diagnose fault codes of heavy-duty truck engines, the most common are Paccar and Cummins engines. These are the two leading brands that are optimized to be handled by the Jaltest heavy-duty truck diagnostic software. Fault diagnosis and clearance are so critical in these two cases that they will be seen in some detail individually.
Cummins heavy-duty engines
The Jaltest heavy-duty diagnostic computer offers deep coverage to Cummins engines, from Cummins X15 to Cummins L19 and more. The software takes you through reading and clearing fault codes, performing system checks, calibrating VGTs and turbos, completing after-treatment checks, and more.

All these procedures are simplified through detailed wiring diagrams and live technical information in real-time, thereby allowing you to set parameters like maximum speed and idle speed, and perform checks on fuel and EGR systems. You can either carry out full system scans to prevent any major fault that might lead to downtime or do scans by symptoms for specific fault codes.
The Extra-High-Pressure Injection and Common Rail included in the dashboard of the Jaltest diagnostic computer for heavy-duty construction trucks offers several functions. You can monitor, maintain, calibrate, configure, and actuate components of Cummins engines with our optimized software.
Paccar MS11 – MX13 Engines
As in Cummins engines, the Jaltest maintenance tool for Paccar engines also offers a range of functionalities. The user-friendly menu allows you to carry out full system scans to check various metrics like the central computer, chassis module, electronic module, climate HVAC, lighting, instrument cluster, and more.
Additionally, with our user-friendly heavy-duty truck diagnostic scanner, you can modify several metrics to meet specific running conditions. For example, you can set parameters so that your heavy-duty truck works easily on even the most challenging terrains.

Some of the parameters that can be changed to meet your desired operating goals are fuel consumption, engine speed control, power take-off control, activating and deactivating conditions of the brake pedal, and more. Our Heavy truck diagnostic software also covers Paccar body modules and can actuate components like switches and lights to test functionality.
Once you go through all these processes periodically, you ensure that your fleet of heavy-duty trucks is always operating at their highest productivity levels.

Forced Regens and Jaltest Heavy Equipment Diagnostic Tool
Most heavy-duty trucks, off-highway vehicles, and construction equipment are powered by diesel engines that have a diesel particulate filter (DPF) that cuts down on particles in the emissions. This makes for a cleaner environment.
However, if not attended to and cleaned regularly, soot and other particles accumulate in the DPF, lowering engine performance, increasing fuel consumption, and in worst-case scenarios, pushing the vehicle or equipment to limp mode.

In such cases, a fault code will show on the display of the onboard computer and when connected to the Jaltest heavy equipment diagnostic tool, you will be guided on the best way to clear the soot accumulation in the DPF. This is done through forced regeneration or forced regens, an activity that becomes necessary when passive regens are unable to clear the built-up soot.
The process involves running the vehicle or construction equipment at high rev for about 40 minutes. The rise in temperature of the exhaust gasses burns away the soot, thereby cleaning the DPF. Based on the extent of soot in the DPF, our software will guide you on the engine rev and the time required for forced regens.
