South Bend, IN

What Is the Standard Diagnostic System for All Vehicles?

In the intricate world of vehicle diagnostics, the standard varies. For automobiles, the OBD2 16-pin connectors and corresponding readers are commonplace. However, when it comes to heavy-duty trucks and buses, the industry relies on the SAE J1939 or FMS standard. These systems play a crucial role in identifying and rectifying issues, ensuring optimal performance.

What Are the 3 Most Common Causes of Electrical Problems?

Electrical issues in heavy-duty trucks often stem from a few common causes. Faulty wiring, characterized by wear, deterioration, or damage, can result in intermittent or complete power loss, flickering lights, or malfunctioning components. Battery-related problems, including weak or dead batteries, frequently contribute to difficulties in starting, dimming lights, or sporadic electrical failures. 

Another prevalent cause is a malfunctioning alternator, responsible for generating electrical power. Implementing preventive measures and seeking professional assistance when needed can help mitigate these common electrical problems in heavy-duty trucks.
