Rear View Mirrors - Exterior, Power Folding




Rear View Mirrors - Exterior, Power Folding

Overview

The vehicle may be equipped with manual or power fold mirrors. When equipped with power fold mirrors, the side mirrors fold simultaneously using the exterior mirror control switch. The RH (Right Hand) power fold mirror completes its fold slightly faster than the LH (Left Hand) mirror due to a shorter angular fold distance. Press the button to fold the mirrors in or out. The power fold mirrors may be folded or unfolded manually. However, if a mirror is moved manually, they must be re-synchronized.

System Operation

System Diagram






Rear View Mirrors - Exterior, Power Folding

The optional power folding exterior mirrors are controlled by the DSM (Driver Seat Module). The power folding exterior mirror feature allows both exterior mirrors to be folded or unfolded using the exterior mirror control switch that is integral to the master window control switch. The DSM (Driver Seat Module) controls power folding mirror movement by reversing the polarity of voltage and ground it supplies to the power folding mirror motors. The RH (Right Hand) and LH (Left Hand) power folding mirrors fold or unfold at the same time and cannot be controlled independently. The mirrors operate in the opposite direction of the last switch activation.

The DSM (Driver Seat Module) controls power fold mirror operation but does not use memory mirror potentiometer information for operation of the power fold mirrors.

If the power folding mirrors are folded or unfolded continuously (6 to 10 cycles), the power lockout feature disables the system for approximately 3-10 minutes to prevent damage to the power folding mirror drive motors. After 3-10 minutes have elapsed, normal operation resumes. Before running a self-test or retrieving DTCs (Diagnostic Trouble Codes), the power fold switch must be inactive for at least 30 seconds.

The power fold mirrors may be moved inward/outward manually. If a mirror is moved manually, it needs to be re-synchronized. A mirror which has not been re-synchronized may appear to be loose. REFER to Mirror Synchronization - Exterior, Power Folding Programming and Relearning.

Component Description

Exterior Mirror Control Switch

The exterior mirror control switch is integral to the master window control switch. The power fold mirror control switch provides the driver with the controls to fold or unfold the driver and passenger mirror. The power fold mirror control switch is integral to the master window control switch. When the ignition is ON and the power fold control switch button is pressed, a signal is sent to the DSM (Driver Seat Module). The DSM (Driver Seat Module) then supplies voltage and ground to the power fold motors to fold or unfold the mirrors.

Driver Seat Module (DSM)

The DSM (Driver Seat Module) incorporates multiple functions into one module and offers diagnostics to easily locate and repair concerns affecting the subsystems that it controls. The power folding mirrors are controlled by the DSM (Driver Seat Module). The DSM (Driver Seat Module) is capable of setting DTCs (Diagnostic Trouble Codes) for the memory and power folding mirrors when a system concern exists. For additional information on the DSM (Driver Seat Module), REFER to Driver Seat Module (DSM) Seating - 1st Row - Memory.

Exterior Mirror

Each optional 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
