What Is A Fault Code On A Truck?
A fault code is a message generated by a truck’s onboard computer to indicate a problem with one of its systems—like the engine, transmission, ABS, or emissions controls. It helps technicians identify and repair specific issues.
Why Won’t My Truck Start But The Lights Come On?
If your truck won’t start but lights work, the issue could be with the starter, ignition switch, battery cables, or a faulty sensor. Professional diagnostics can quickly determine the exact cause.
