Power Mirror Switch - Operation

OPERATION

The power operated outside rear view mirrors are connected to battery current at all times. Each mirror head contains two electric motors, two drive mechanisms, an electric heating element and the mirror glass. A mirror selector switch button is depressed in the driver door power switch module to determine whether the mirror adjuster switch will have control over the right or left mirror.

The driver door power switch module sends power mirror switch status messages over the Local Interface Network (LIN) data bus to the driver front door control module. The driver front door control module then controls the high current outputs to the driver door mirror motors or sends electronic request messages over the Controller Area Network (CAN) Interior High Speed (IHS) data bus to the passenger front door control module to control high current outputs to the passenger door mirror motors.
