Diagnostics are an important aspect of modern vehicle maintenance and repair. Your car, truck, or SUV is equipped with an array of computers and sensors which monitor your engine activity and flag anything that isn’t operating as it should. Check engine lights and other dash lights are activated whenever a problem arises, and special equipment and technicians who know how to use it are necessary to diagnose and correct a problem. Performing diagnostics can assist mechanics in pinpointing the critical issues and reduce the time needed for guessing. Our expert mechanics at Dennis Johnson's Auto Repair in Madison have both the technology and the know how to read engine codes and perform repairs or maintenance. No matter what your issue is, whether it’s a failed sensor, a malfunctioning catalytic converter, a misfire, a fuel delivery issue, or anything else your vehicle may need, Dennis Johnson's Auto Repair has you covered.

Dash warning lights can be serious and indicate potential harm to your engine if ignored and should be taken care of as soon as possible. Warning lights such as BAS, ESP, ABS, etc. can range from problems with your brakes or issues pertaining to the electrical systems. Diagnostics are integral to ensure safe trips and driving, which are the abilities Dennis Johnson's Auto Repair strives to equip our customers with.
