Battery, charging and starting issues; module and network communication faults; and problems with wiring, sensors and actuators — including intermittent faults that are hard to pin down.
Intermittent faults are exactly what we specialize in tracing. They take patience and the right tools to read the vehicle's networks and isolate a cause that others give up on.
Modern vehicles are essentially computers on wheels, with modules communicating over networks. Finding a fault means tracing circuits and testing modules, not just replacing a part.
It can be. Starting trouble often traces back to the battery, charging or starting system, which we test to determine the actual cause before recommending a fix.
