System Operation - Exterior, Power, Without Memory

All functions of the power mirror feature are integrated into one switch module (integral to the LH front door window control switch). The left and right side selection buttons have an LED to indicate which side is active and a directional pad is used for directional control. Neutral is achieved by pressing the lit button to deactivate the left or right exterior mirror, or by allowing the system to time out and reset to neutral.

When the exterior mirror directional pad switch is pressed left, right, up or down with the LH or RH exterior mirror selected, the movement request is sent to the DDM through a LIN circuit. 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 with the input from the exterior mirror control switch to the PDM over the MS-CAN. The PDM then supplies voltage and ground to the appropriate RH exterior mirror motor. The DDM and PDM controls the glass movements by reversing polarity of the voltage and ground circuits being supplied to each motor.
