Power Memory Mirrors
CIRCUIT OPERATIONThe power memory mirror system used in this vehicle uses a control module, power mirror switch, power mirror motors, mirror potentiometers, and a memory set switch. This control module is also shared and used for the power memory seat.
Power for the memory control module is supplied on two circuits. Circuit F35 provides a constant battery feed. This circuit is protected by a 30 Amp circuit breaker located under the drivers seat. Power for the F35 circuit is supplied on circuit A3. The A3 circuit is HOT at all times and protected by a 40 Amp fuse located in cavity 2 of the Power Distribution Center (PDC).
The M1 circuit also supplies battery voltage to the control module. This circuit is the Ignition-Off Draw (IOD) circuit, and protected by a 10 Amp fuse located in cavity 10 of the PDC.
Ground for the control module is supplied on circuit Z1. This circuit terminates at the instrument panel left side cowl.
Power for the mirror switch is supplied on circuit F41. This circuit is protected by a 15 Amp fuse located in cavity 11 of the Power Distribution Center (PDC). Grounding for the power mirrors is provided through the Z1 circuit, which terminates at the instrument panel left side cowl.
The power mirror switch also has a Light Emitting Diode (LED) located in it for night illumination. Power for the LED is supplied on circuit E2. This is the illumination output from the Body Control Module (BCM).
To control the operation of the mirrors, the circuits that supply power to the mirror motors are also connected to the control module. Operation of the motors and ground circuit is the same.
