Check Engine Light Diagnostics FAQs
Is a free code scan the same as a diagnosis?
No. A code points to a system; our technicians test components to confirm the actual failed part so you don't pay for guesswork.
Can I drive with the check engine light on?
If it's steady, usually for a short time. If it's flashing, stop driving — it signals a misfire that can destroy the catalytic converter.
Is the diagnostic fee applied to the repair?
Yes, the diagnostic fee is credited when you approve the repair with us.
Do you diagnose hybrids and EVs?
We diagnose most hybrids and the 12-volt and accessory systems on many EVs.
