Check-engine-light testing beyond reading a code

Check-engine light — Charlotte Service Hub scans the vehicle, documents relevant codes and data, considers the reported symptoms, and performs targeted accessible tests to distinguish a likely cause from a code that only describes the detected condition.

Mobile service only. No customer-facing shop location. Service is available by appointment.

Service questions

Questions about check-engine light

Can you diagnose a check-engine light on-site?

Many common faults can be evaluated on-site with scan data, visual inspection, electrical checks, and accessible operating tests. Some faults require smoke machines, lift access, programming, or longer monitored drives.

Is it safe to drive with the check-engine light on?

A steady light may still need prompt diagnosis. A flashing light, overheating, severe shaking, loss of power, fuel odor, or abnormal noise is a reason to stop and arrange safer evaluation.

Will you clear the code?

Codes may be cleared only when appropriate after information is recorded and the customer understands that clearing a code does not correct the cause.
