Heavy-duty trucks, construction, and material handling equipment are the lifeline of any nation, moving goods and helping build large infrastructure effortlessly. However, if you have a fleet of such trucks and equipment, a heavy-duty scan tool should be a must-have for you.
What is the function of such a tool that helps your fleet always be on the job without frequent breakdowns?
All modern heavy-duty trucks and equipment have a central computer that tracks the health of the vehicle and equipment through the display of fault codes. These codes are shown on the display panel usually located below the dashboard on the driver’s side. Every code, also known as Diagnostic Trouble Codes (DTCs), corresponds to a specific malfunction and is typically standardized in particular makes and models of trucks and equipment.
When a fault code shows up, you need a heavy-duty diagnostic tool to understand the nature of the fault. It might be related to the engine, transmission, hydraulics, or other systems. The tool will then guide you through the procedures to rectify the problem and bring your vehicle back on the road as soon as possible.
One of the most effective and optimized heavy-duty diagnostic software is offered by Jaltest. Our maintenance tool offers users two options to ensure that vehicles are performing well. One is the preventive process and the other is maintenance procedures.
In the first case, you can periodically carry out full system scans to check the status of your equipment. If a fault is found, quick action can be initiated to solve it immediately before it becomes a major issue. These are known as temporary fault codes and do not persist over time.
The other instance is when a fault code that is more permanent shows up and carries on over several driving cycles. Here, your Jaltest heavy-duty scan tool will guide you on how to correct the malfunction with dealer-level service and without the use of manuals.
Using the Heavy-Duty Truck Diagnostic Tool
The Jaltest heavy-duty truck diagnostic tool is a class apart from its competitors and caters to the maintenance needs of most major brands of heavy-duty trucks. These include Kenworth, Paccar, Mack, Freightliner, International, Allison, Peterbilt, Cummins, Detroit, Bendix Western Star, Volvo, and more.
If you have a mixed fleet, you do not need several versions of a heavy-duty scan tool, the Jaltest software is enough for implementing fault code rectification on all these brands and their various models. It covers various systems such as engines, brakes, hydraulics, transmissions, and truck bodies, and provides cutting-edge maintenance data that can be tracked through live data monitoring to clear fault codes.
With the Jaltest heavy-duty diagnostic laptop, you get in-depth coverage and detailed technical information about almost all fault code rectification processes. We even handhold you through component replacement procedures, how to remove the parts, and check whether they can be reused. You can also actuate body components, calibrate VGT and code injectors, calibrate transmissions, get wiring diagrams, technical information, and repair times.

Jaltest Heavy-Duty Diesel Scanner And Forced Regens
Our heavy-duty diagnostic tool ensures that you can manage after-treatment systems and perform forced regens, system checks, calibrations, parameter settings, and more.
Forced regens is a very critical maintenance activity that must be carried out on heavy-duty vehicles and equipment powered by diesel engines. It is a very complex activity but is greatly simplified by the Jaltest heavy-duty diesel scanner.
All diesel engines face soot buildup in the diesel particulate filter and in severe cases, pushes the vehicle or equipment into limp mode. Forced regens is the highest level of DPF regeneration, burning away the soot when passive regens cannot clear the DPF. Soot buildup in the DPF is common when heavy-duty trucks and vehicles go through repeated start-stop cycles and not continuous long-haul operations.
When soot buildup is found in the fault code reader of our Jaltest heavy-duty diagnostic scanner, the solution is to run the engine on stationery vehicles continuously for about 40 minutes at a specific RPM as guided by our maintenance tool. This raises the temperature of the exhaust gasses and the soot is burnt off. You can choose between High and Very High forced regens depending on the extent of soot buildup.
While forced regens are carried out by certified engineers, they are guided by the heavy-duty diesel scanner. Along with forced regens, our software also advises you when the injector code in the Electronic Control Module (ECM) needs to be replaced or installed.
