What Are Diagnostics & Inspections?
- Diagnostics identify the root cause behind warning lights, rough running, noises, leaks, and electrical faults using professional scan tools, live data, and targeted testing.
- Inspections evaluate overall vehicle health—brakes, suspension, tires, fluids, cooling system, steering, and more—so you know what needs attention now versus later.
Why This Service Matters
- Ends guesswork and saves money by fixing the real issue
- Improves safety and prevents roadside breakdowns
- Helps plan maintenance and protect high‑value components
- Keeps your vehicle inspection‑ready and emissions compliant
Important to Know
- Typical on‑site time: 45–90 minutes; complex or intermittent faults may require additional testing.
- Your diagnostic fee is credited toward approved repairs with Nationwide Mechanics.
- You’ll receive a clear digital report with findings, photos (when helpful), and a firm estimate.
- Advanced procedures (deep wiring repairs, module programming, partial tear‑downs) may be quoted separately.
- This is not a state inspection; it’s a comprehensive pre‑check to help you pass.
How Diagnostics & Inspections Are Done
- Interview & Verification
Discuss symptoms, recent work, and driving conditions; confirm the concern. - Baseline Checks
Battery/charging test, fluids, fuses/grounds, belts/hoses, air intake, and a visual leak check. - Scan & Data Review
Read DTCs, freeze‑frame, Mode 6; review TSBs and service information relevant to your vehicle. - Functional & Road Tests
Live‑data monitoring, actuator tests, short road test (if safe), brake feel, steering feedback, HVAC performance. - Pinpoint Testing (as needed)
Electrical circuit testing, smoke test for vacuum/EVAP leaks, fuel pressure/volume, compression/leak‑down, oil pressure, cooling system pressure/block test. - Report & Estimate
Root cause explained in plain language with priorities (Now / Soon / Monitor) and repair options.
Systems We Diagnose & Inspect
- Engine/Powertrain (misfires, rough idle, stalling, fuel trims)
- Electrical/Charging (battery drain, alternator, starter, wiring)

- Suspension/Steering (shocks/struts, ball joints, tie rods, bearings)
- Cooling/Heating (radiator, fans, thermostat, heater performance)
- HVAC/AC (compressor, blend doors, pressures/temps)
- Transmission/Drivetrain (shift quality, sensors, mounts, CV/axles)
- Emissions/EVAP (readiness monitors, leak detection, inspection failures)
