Questions about Mobile Diagnostics?

Can you diagnose a car that will not start?

Yes. We test the battery, starter signal, charging system, fuel/ignition clues, and related basics instead of guessing at parts.

Do you only scan codes?

No. A scan is only one part of diagnostics. We use codes as a starting point and verify the likely cause with practical testing.
