Power Mirror Operation
When the LH or RH exterior mirror is selected with the exterior mirror selection switch and the exterior mirror control switch is pressed up, down, left or right, the command is sent through a LIN circuit between the LH front window control switch and the DDM. If the LH mirror is selected, the DDM supplies voltage and ground to the appropriate LH exterior mirror motor. If the RH mirror is selected, the DDM sends the passenger mirror command message through the MS-CAN to the PDM. Based on the passenger mirror command message, the PDM supplies voltage and ground to the appropriate RH exterior mirror motor.
