Auto-Dimming Mirror Inspection
- Measure the voltage at each terminal (other than terminal F).
- If the voltage is not as specified in Terminal Voltage Table (Reference), inspect the parts under "Inspection items(s)" and related wiring harnesses.
- Disconnect the negative battery cable.
- Inspect the auto-dimming mirror connector for continuity at terminal F.
- If the system does not work properly even though the inspection items or related wiring harnesses do not have any malfunction, replace the auto-dimming mirror.
