Mazda CX-5 Service & Repair Manual: Auto Dimming Mirror
Purpose
-
The automatic glare prevention rearview mirror prevents the driver from being affected by light from vehicles at the rear.
Structural view
System wiring diagram
Function
-
The automatic glare prevention rearview mirror detects the level of the surrounding light and glare from vehicles at the rear using the light sensor.
-
The automatic glare prevention rearview mirror combines the level of the surrounding light and the glare from vehicles at the rear and changes the reflection rate of the mirror between 10% and 70%.
-
When the automatic glare prevention rearview mirror receives a reverse signal from the rear body control module (RBCM), the reflection rate of the mirror is fixed at 70% or more.
Operation
-
When the automatic glare prevention rearview mirror switch is turned on, the mirror switches to automatic glare prevention mode.
-
While in automatic glare prevention mode, the light sensor detects the level of surrounding light and the glare from vehicles at the rear.(1)
-
The automatic glare prevention rearview mirror changes the voltage applied to the mirror according to the level of the surrounding light and the glare from vehicles at the rear.(2)
-
The mirror changes the reflection rate between 10% and 70% according to the voltage that is applied.
-
However, if it receives a reverse signal from the rear body control module (RBCM) (3), the reflection rate of the mirror is fixed at 70% or more.

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 h ...
Other materials:
ABS Wheel Speed Sensor And ABS Sensor Rotor
Purpose/Function
The ABS wheel-speed sensor and ABS sensor rotor detect the rotation condition
of each wheel and transmit this information to the DSC HU/CM.
The signal from the ABS wheel-speed sensor is the primary signal that the
DSC HU/CM uses when carrying out control.

Crankshaft Position (CKP) Sensor Inspection
Visual Inspection
CAUTION:
When foreign material such as an iron chip is on the CKP sensor, it can cause
abnormal output from the sensor because of flux turbulence and adversely affect
the engine control. Be sure there is no foreign material on the CKP sensor when
replacing.

Magnet Clutch [Full Auto Air Conditioner]
Purpose
The magnetic clutch transmits the rotation force from the engine to the shaft
in the A/C compressor.
Function
The magnetic clutch engages or disengages the magnetic clutch and the A/C
turns on or off by switching the power transmission from the engine.
