Once your Diagnostic Trouble Codes (DTCs) have been pulled from the vehicles on board computer, our trained technicians will get to work diagnosing the issue. A road test by a trained technician will be performed on the vehicle to verify and look for drivability issues. Once the road test is complete, the vehicle will return to the bay for a visual inspection. The visual inspection looks for vacuum or electrical related issues. The vehicle's battery and charging system will be tested to ensure a power issue is not the cause of the malfunction. Additional tests such as a compression test, fuel pressure test, and spark tests may be needed to identify the problem.
