What Is an Automotive Diagnostic?
Automotive diagnostics involve much more than plugging in a scan tool. At Tommy’s Auto and Performance, we use advanced diagnostic equipment, manufacturer‑approved data, and hands‑on testing to communicate directly with your vehicle’s onboard computer systems and pinpoint faults within:
- Engine and drivetrain systems
- Transmission and driveline components
- ABS, traction control, and stability systems
- Electrical and charging systems
- Heating and air conditioning systems
- Safety and driver‑assist technologies
Accurate diagnostics allow us to fix the root cause of the problem—preventing unnecessary repairs and saving you money.
