Advanced Computer Diagnostics & Electrical Repair

Check engine lights, intermittent electrical glitches, and sensor faults create real breakdown anxiety.

The problem we solve

Check engine lights, intermittent electrical glitches, and sensor faults create real breakdown anxiety. Our diagnostic-first testing isolates the fault accurately the first time, so you avoid unnecessary parts swapping and lingering warnings.

What we do

Today's vehicles are computer networks on wheels with dozens of modules, sensors, and harnesses. We use advanced scanners, oscilloscopes, and circuit testing to evaluate module communication, sensor signals, charging output, and wiring integrity. That covers ADAS calibration, ECU coding, battery management, and parasitic draw tracing. You get a clear digital report explaining the findings before any repair is approved, so the fix matches the actual fault.

  • ADAS calibration
  • Engine diagnostics and repair
  • Check-engine-light diagnostics

Every repair at Valette Auto Repair is backed by our comprehensive 2-Year / 24,000-Mile Warranty on all parts and labor, providing complete peace of mind.
