5.  While the indicator light is illuminated, verify that the mirror surface brightens.

6.  Cover the day/night sensor with a hand and verify that the mirror surface darkens when light is shone on the glare detection sensor.

7.  Remove your hand covering the day/night 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.  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. (See AUTO-DIMMING MIRROR REMOVAL.) (See AUTO-DIMMING MIRROR INSTALLATION.)
