Mazda 3 Service Manual: Auto Dimming Mirror Inspection
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.
