How We Diagnose a Check Engine Light
Diagnosing a check engine light is typically done with a computerized scan that we connect to your car. The car sends a code to our device letting us know why your check engine light, brake light, oil light, tire light, or battery light is on. Once we have diagnosed the reason why we can then recommend a course of action to repair your vehicle.
