Component Description

Exterior Mirror Control Switch

The exterior mirror control switch is integral to the master window control switch. The exterior mirror control switch provides the driver with the controls to move the driver and passenger's exterior rear view mirrors left, right, up or down. When the ignition is ON and the exterior mirror control switch button is pressed, the selected mirror is adjusted to the left, right, up or down position. Voltage and ground is supplied to the selected exterior mirror motor from the DDM (Driver Door Module) or PDM (Passenger Door Module) to move the exterior mirror glass to the desired position.

Exterior Mirror

There are 2 bi-directional motors in each exterior mirror that control the up/down and left/right movement of the exterior rear view mirror glass.

The RH (Right Hand) exterior mirror contains the ambient temperature sensor.

Driver Door Module (DDM)

The DDM (Driver Door Module) receives mirror movement requests through a proprietary LIN (Local Interconnect Network) circuit from the master window control switch. The DDM (Driver Door Module) then provides voltage and ground to the LH (Left Hand) exterior mirror motor to drive it in the desired direction.

When the master window control switch requests RH (Right Hand) exterior mirror functions, the DDM (Driver Door Module) sends the requests to the PDM (Passenger Door Module) through the MS-CAN (Medium Speed Controller Area Network). REFER to Passenger Door Module (PDM).

Passenger Door Module (PDM)

When the master window control switch requests RH (Right Hand) exterior mirror functions, the DDM (Driver Door Module) sends the requests to the PDM (Passenger Door Module) through the MS-CAN (Medium Speed Controller Area Network). The PDM (Passenger Door Module) then provides voltage and ground to the RH (Right Hand) exterior mirror motor to drive it in the desired direction.
