System Operation - Exterior, Power Fold

NOTE: If the exterior mirrors are folded and unfolded several times consecutively, the power lockout feature disables the system for approximately 3-10 minutes to prevent damage to the power fold motors. After 3-10 minutes have elapsed, normal operation resumes.

NOTE: The power folding mirrors must be synchronized anytime the LH, RH or both power folding mirrors are folded or unfolded without using the power folding mirror control switch, the automatic folding feature or if a new power folding mirror has been installed. Refer to Power Mirrors Synchronization

NOTE: If the exterior mirrors are folded by pressing the exterior mirror fold switch, the automatic folding feature is disabled until the mirrors are unfolded by pressing the exterior mirror fold switch.

NOTE: The power folding mirrors may not fold and/or unfold at the same rate of speed. This is a normal operation of the power folding mirrors.

The exterior mirrors have a power fold feature that can be activated manually or automatically (if equipped). The exterior mirrors can be manually folded and unfolded by pressing the exterior mirror fold switch (integral to the LH front door window control switch). When the automatic folding feature is turned on in the IPC message center, the exterior mirrors automatically fold in when the vehicle is locked, after the transmission is placed in park and the driver door is opened and closed. The mirrors automatically fold out when the vehicle is unlocked and the LH front door is opened and closed. The LH and RH power folding mirrors fold or unfold at the same time and cannot be controlled independently.

When the ignition is on and the exterior mirror fold switch is pressed, the fold request is sent to the DDM via the LIN. When the fold request is received, the DDM checks it's internal memory to determine the last exterior mirror fold movement that was commanded (fold or unfold). The DDM supplies voltage and ground to the LH exterior mirror folding motor and sends the passenger mirror command message to the PDM over the MS-CAN. The PDM uses this message to supply voltage and ground to the RH exterior mirror folding motor. When the exterior mirror fold switch is pressed again, the DDM reverses the polarity of the voltage supplied to the LH exterior mirror folding motor and sends the passenger mirror command message to the PDM over the MS-CAN, which reverses the polarity of the voltage supplied to the RH exterior mirror folding motor.

When the driver turns the automatic folding feature on or off in the IPC message center, the personality data message containing the selection is sent from the IPC to the DDM, with the GWM acting as a gateway. When automatic folding is turned on, the DDM monitors the ignition status and vehicle lock status messages from the BCM as well as the gear position message from the PCM. When the transmission is placed in park, the ignition is turned off, the LH front door is opened and closed and the vehicle is locked using the RKE or door switch, the DDM supplies voltage to the LH exterior mirror folding motor and sends the passenger mirror command message to the PDM over the MS-CAN, which supplies voltage to the RH exterior mirror folding motor. The exterior mirrors remain folded until the vehicle is unlocked and the LH front door is opened and closed. After the door is closed, the DDM reverses the polarity of the voltage supplied to the LH exterior mirror folding motor and sends the passenger mirror command message to the PDM over the MS-CAN, which reverses the polarity of the voltage supplied to the RH exterior mirror folding motor.

Each power fold exterior rear view mirror has an internal motor to fold or unfold the mirror that is not replaceable. If a power folding mirror drive motor is found to be inoperative, a new power folding exterior rear view mirror assembly must be installed.
