You may need diagnostic testing if your check engine light is on, your car stalls frequently, or you notice unusual noises or performance issues. Modern diagnostic tools read error codes from your vehicle’s onboard computer, helping technicians quickly identify and fix specific problems before they worsen.

Exhaust issues often arise from rust, road debris damage, or failing components like the catalytic converter or muffler. These problems can lead to reduced fuel efficiency, loud noises, and increased emissions, which can only be accurately identified through inspection and testing by a trained technician.

Common causes include a weak battery, worn alternator, blown fuses, or corroded wiring. Since electrical systems power essential functions—like ignition, lights, and sensors—technicians use specialized diagnostic tools to test voltage, continuity, and current flow to pinpoint the source of the issue.

If your car hesitates when shifting, produces grinding noises, or leaks reddish fluid, it could signal transmission wear or damage. A technician will perform a fluid check, test drive, and system scan to determine if repairs, adjustments, or a rebuild are necessary.

Steering and suspension components should be inspected at least once a year or every 12,000 miles. Regular checks help detect worn shocks, struts, or tie rods that affect vehicle stability, ride comfort, and tire alignment, preventing uneven wear and maintaining smooth handling.
