What to Know
The check engine light can indicate anything from a loose gas cap to a serious engine or emissions issue.
Modern vehicles store diagnostic trouble codes (DTCs) that a scan tool can read to identify the source of the problem.
A flashing check engine light typically means a more urgent issue — like a misfire — that can damage your catalytic converter if ignored.
At JDM, we use professional-grade diagnostic equipment to read codes and perform a thorough inspection before recommending any repairs.
When to Schedule
- As soon as the check engine light comes on
- Immediately if the light is flashing
- Before your vehicle's emissions test
- If you notice any performance changes alongside the light
