System Operation - Exterior, Power Fold

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: If the exterior mirrors are folded and unfolded several times consecutively, the power folding feature is disabled for approximately 3-10 minutes to prevent damage to the exterior mirror folding motors.

The exterior mirrors have a power fold feature that can be activated manually or automatically. The exterior mirrors can be manually folded and unfolded by pressing the exterior mirror fold switch (integral to the LH front 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 auto-fold feature is disabled if the mirrors are folded manually using the exterior mirror fold switch.

When the ignition is on and a mirror fold is initiated by pressing the exterior mirror fold switch, the DDM supplies voltage and ground to the LH exterior mirror folding motor and sends the passenger mirror command message to the PDM. 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, 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, ignition is turned off, LH front door is opened and closed and the vehicle is locked using the passive key or door switch, the DDM supplies voltage to the LH exterior mirror folding motor and sends the passenger mirror command message to the PDM, 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, which reverses the polarity of the voltage supplied to the RH exterior mirror folding motor.
