Common Types of Diesel Truck Electrical Repairs
In recent years, truck electronics have advanced significantly. Your truck’s performance depends on its electrical system which at times can feel like a complex maze. Onsite’s certified diesel mechanics are familiar with navigating the electrical mazes in big trucks. Some common repairs we help customers with include:
- ECU Unit repair
- Circuit protection device replacement
- Dead battery replacement
- Head and tail light wiring and fuse repair
Check Engine Light Issues
When your check engine light pops on don’t ignore it. It could be something simple like a loose or faulty gas cap or a more severe issue like a bad catalytic converter. Whatever the cause, it’s best not to take a chance of causing significant damage.
Diagnostic Testing & Adjustments
Our shop has the necessary software to not only pinpoint issues, but we can adjust parameters in all engines. If your truck doesn’t seem to be running the way it should, we’ll conduct a diagnostic test to determine the problem. Diagnostic testing can reveal issues in your truck’s engine, transmission, exhaust system, brakes, and other major components.
Engine Control Unit (ECU) Repair
A malfunctioning Engine Control Unit (ECU) is one of the most typical electrical issues with semi-trucks. The ECU controls the timing and fuel injection of the engine, and keeps an eye on the engine’s sensors and emission control mechanism. Your engine won’t operate correctly and stall if the ECU isn’t working properly.
Wiring Repair
Wires get loose and break over time due to your truck’s continuous vibration. This introduces risks like short circuits and even fire. The electrical “noise” that unsecured cables may produce can also interfere with your truck’s onboard computer systems. Compromised circuit protectors can let too much current pass through the electrical system and result in a catastrophic power surge.
