What Are Diagnostics & Inspections and How Do They Work?
Diagnostics identify the root cause behind warning lights, rough running, noises, leaks, and electrical faults using professional scan tools, live data, and targeted tests. Inspections assess overall vehicle health and safety—checking brakes, suspension, tires, fluids, cooling, and more. Together, they prevent guesswork, save money, and keep your car reliable.

How Diagnostics & Inspections Are Done
- Interview and Verification
Discuss symptoms, driving conditions, and recent work; confirm the concern. - Baseline Checks
Battery/charging test, fluid levels/condition, leaks, belts/hoses, air filter, and visual inspection. - Scan and Data Review
Read codes, freeze‑frame, Mode 6; review TSBs and service information. - Functional and Road Tests
Live data monitoring, actuator tests, short road test (if safe), brake and steering feel, HVAC performance. - Pinpoint Testing (as needed)
Electrical circuit tests, smoke test for vacuum/EVAP leaks, fuel pressure/volume, compression/leak‑down, oil pressure, cooling system pressure/block test. - Report and Estimate
Clear explanation of the root cause, what failed and why, priority levels, and repair options.
