Component Description
Exterior Mirror Control Switch
The exterior mirror control switch is integral to the LH front door window control switch and connected to the DDM through a LIN circuit. The exterior mirror control switch incorporates a selection switch to allow the driver to determine which exterior mirror is adjusted.
Exterior Mirror
For the power mirror function, each exterior mirror has 2 bi-directional motors that are used to control the position of the exterior mirror glass.
The heated exterior mirrors use heating elements that are integral to the exterior mirror glass.
The exterior mirrors use a jumper harness between the vehicle wiring harness and the exterior mirror motors and the heated mirror glass. The exterior mirror jumper harness is integral to the exterior mirror. Before replacing an exterior mirror or motor, inspect the jumper harness for opens, shorted circuits or damaged and pushed-out pins. If a concern with the exterior mirror jumper harness exists, attempt to repair the jumper harness.
The exterior mirrors include turn signals indicators. For additional information on the mirror-mounted turn signals indicators, REFER to: Exterior Lighting - System Operation and Component Description
The exterior mirrors may include puddle lamps. For additional information on the mirror-mounted puddle lamps, REFER to: Interior Lighting - System Operation and Component Description
The exterior mirrors may include BLIS®/ CTA Light Emitting Diodes (LEDs). For additional information on the mirror-mounted BLIS®/ CTA system, REFER to: Blind Spot Information System - System Operation and Component Description
DDM
For the power mirror function, the DDM receives mirror movement requests through the LIN circuit from the LH front door window control switch. The DDM then provides voltage and ground to the appropriate LH exterior mirror motor to drive the mirror glass in the desired direction.
When the LH front door window control switch requests RH exterior mirror functions, the DDM sends the requests to the PDM through the MS-CAN.
For the heated mirror function, the DDM supplies voltage to the LH exterior mirror glass heating element based on messages received the BCM.
When a concern exists, the DDM is capable of setting and storing Diagnostic Trouble Codes (DTCs) for the LH exterior mirror motor drive circuits and mirror heater circuit (if equipped).
PDM
For the power mirror function, the PDM controls the RH exterior mirror glass position by supplying voltage and ground to the RH mirror motors based on the messages received from the DDM through the MS-CAN.
For the heated mirror function, the PDM supplies voltage to the RH exterior mirror glass heating element based on messages received the BCM.
When a concern exists, the PDM is capable of setting and storing Diagnostic Trouble Codes (DTCs) for the RH exterior mirror motor drive circuits and mirror heater circuit (if equipped).
Interior Rear View Mirror - Manual-Dimming
The manual dimming interior rear view mirror has a lever at the back of the mirror that must be pulled forward or pushed rearward by the driver to activate the manual dimming function. Manual dimming is completely controlled by the driver.
Interior Rear View Mirror - Auto-Dimming (if equipped)
The auto-dimming rear view mirror has 2 photoelectric sensors, forward facing and rearward facing, that detect forward and rearward light conditions. Based on inputs from these sensors, the automatic dimming feature adjusts the reflectance level of the interior rear view mirror glass to eliminate unwanted glare. The reflectance level of the mirror glass is variable and depends on the amount of rear glare in relation to ambient light conditions in front of the interior mirror.
