Instrument cluster came in with incorrect speedometer readings and partial backlight failure following moisture ingress.
Work performed:
- Board-level diagnostics — oxidation traces identified on circuit paths
- Circuit track restoration, cleaning and anti-corrosion treatment
- Replacement of faulty SMD backlight components
- Odometer correction after replacement with donor unit
- Speedometer and tachometer calibration
- Full function verification prior to return
Result: Cluster fully restored. All functions operational. Readings aligned with actual vehicle data.
