Intermittent electrical or CAN-bus problem: what should I do?.

Warning lights that come and go, repeated battery problems, and module communication faults need testing tied to the symptom—not guessed parts.

Testing an engine bay at Front Line Auto in Oakland Park

The short version

Intermittent electrical problems can appear as warning lights that come and go, starting or charging trouble, features that stop working, or modules that will not communicate. A stored code can be a clue, but it does not prove the failed part. Front Line Auto starts with the symptom, vehicle history, scan information, wiring and power checks, and related mechanical conditions before quoting a repair. Call with the vehicle details, warning messages, and when the issue occurs.
