Common Questions

Engine Diagnostics FAQ

What does a check engine light mean?
It means your vehicle's onboard computer has detected an issue and stored a fault code. It could be minor — like a loose gas cap or a sensor glitch — or more serious, like an engine misfire or catalytic converter issue. The only way to know is to scan the system.
Can I keep driving with my check engine light on?
A solid check engine light usually means it's okay to drive for a short period, but you should schedule an inspection soon. A flashing or blinking check engine light is more urgent — it typically indicates an active misfire that can damage your catalytic converter. Pull over safely and call us.
Does the diagnostic fee apply toward the repair?
Yes. If you choose to have GB Service Center perform the recommended repair, we'll credit the diagnostic fee toward the cost of your service.
