4. Cover the front light sensor with a hand and verify that the mirror surface darkens when light is shone on the rear light sensor.

5. Remove your hand covering the front light sensor and verify that the mirror surface brightens.

• If the auto-dimming mirror does not operate, inspect the terminal voltage. (See Terminal Voltage Table (Reference).)

Terminal Voltage Table (Reference)

1. Remove the cover. (See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION.)

2. Measure the voltage at each terminal.

• If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under “Inspection item (s)” and related wiring harnesses.

― 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.
