Check Engine & Diagnostics FAQs
Is the diagnostic fee applied to the repair?
Yes. If you approve the repair, the diagnostic fee is credited toward the job.
Can I drive with my check engine light on?
If it's steady, usually for a short time. If it's flashing, stop driving — it often signals a misfire that can damage the catalytic converter.
Do you diagnose electrical problems?
Yes — batteries, alternators, starters, wiring faults, and parasitic draws.
How long does a diagnostic take?
Most diagnostics take 30–60 minutes on site.
