What's included
[Shop Name] uses professional scan tools to read your vehicle's computer and find out why the check-engine light is on. We read the trouble codes, test the system, and pinpoint the real cause the first time — not just clear the light. We explain what's wrong in plain English and what it will cost before any work starts.

Frequently asked questions
My check-engine light is on — is it safe to drive?
Sometimes yes, sometimes no. If the light is flashing, stop driving and call us. A steady light means bring it in soon so a small issue doesn't turn into a big one.
Can you read codes the parts-store scanner can't?
Yes. Free parts-store scans only read basic engine codes. Our tools read every system in the car and let us test components, not just guess.
