Deep Coverage and Maintenance For Peterbilt Truck Engines
Our Peterbilt diagnostic software clears all fault codes for the engines of Peterbilt trucks. While we cover issues with all makes of engines used in Peterbilt trucks, our primary focus is on Paccar and Cummins engines.
Paccar is a name to reckon with and is a global technology leader and manufacturer of truck engines for top truck brands including Peterbilt. Paccar engines are complex and difficult to work with but the Jaltest software helps you to easily diagnose issues including clearing Peterbilt 579 fault codes.
For Peterbilt trucks with Paccar engines, our software enables you to set parameters, actuate components, take live measurements, and read and clear fault codes. You can also activate the power take-off indicator and solenoid valve, instrument cluster, electrical system, pressure, and temperature indicators, and more.
Our software is equally effective for the engine used commonly on Peterbilt trucks and that is the Cummins X15. In this case, too, our software easily handles complex functions such as setting parameters like maximum speed and idle speed, carrying out system checks on fuel systems, EGR systems, aftertreatments systems, calibrating VGT / turbos, and more.
Force Regens To Clear Peterbilt Fault Code List For Engines
Performing force regens is only on diesel-fueled engines where it is common for soot to build up in the diesel particulate filter, thereby pushing the engine towards limp mode and increasing emission levels. This is reflected in the SCR fault code Peterbilt, the Selective Catalytic Reduction system, and indicates that the emission systems need repair and maintenance. The Jaltest software diagnoses the fault code related to the soot buildup and clears it by undertaking force regens.
Our software is highly advanced in this regard, reading the fault code and the extent of soot buildup and offering resolutions from High to Very High accordingly. Additionally, forced regen measures the temperature of the exhaust gasses and the input pressure to ensure that the engine is within set parameters.

Once you interpret these fault codes, you can use the Jaltest software to learn how to initiate corrective action so that your Peterbilt trucks remain safely on the roads.
How to Diagnose and Resolve A Peterbilt Fault Codes
When a fault code shows up on the display panel of Peterbilt trucks, it is critical to diagnose and promptly solve it, not only to avoid downtime but also to prevent further damage that might lead to very expensive repairs.
Here is how a typical Peterbilt truck fault code should be cleared.
# Connect the Jaltest software laptop to the onboard computer of the truck to access the fault code.
# Identify the fault code that consists of alphanumeric characters from our maintenance tool and know the meaning of the fault code and what it represents. This will involve inspecting the various systems and components.
# Resolve the fault code by using the Jaltest software to address the issue. This may involve repairs and adjustments. Our software will guide you if there is any need for component replacement.
Preventive Maintenance vs. Resolutions by Symptoms
To ensure that your fleet of trucks operates always in peak performance mode, it is essential to carry out full system scans of all systems periodically. If there is a fault the issue can be immediately addressed before it becomes a full-blown issue. Our user-friendly diagnostic menu will help you to carry out full system preventive measures so that there is no blowout on the highways.
Full system scans include thorough yet routine inspections of key components like sensors, connectors, and wiring checks. You must also monitor fluid levels as required in the manual including oil, coolant, and fuel, and make sure that they are at desired levels. To prevent any software-related issues, keep the ECM and the truck’s software always updated. Preventive measures go a long way to keep your fleet in peak performance condition.
The other possibility is resolving issues by symptoms after a problem crops up necessitating clearing the Peterbilt fault code list. This type of fault code is of a more permanent nature and persists over several driving cycles. Ignoring these codes is not advisable at all as they might lead to very expensive repairs.
