Description And Operation: Description
Driver and passenger power operated outside rear view mirrors are standard factory-installed equipment. In addition, automatic dimming rear view mirrors, both inside and a driver side outside are available as optional equipment. The power mirror system for this vehicle includes the following major components, which are described in further detail elsewhere in this service information:
- Automatic Dimming Rear View Mirrors (2) - The optional automatic dimming inside rear view microphone mirror is secured to a mounting button on the inside of the windshield glass near the upper windshield opening header. This is the same mounting button that is used for mounting the standard prismatic inside rear view mirror. The optional automatic dimming outside rear view mirror is only available for the driver side door. The automatic dimming outside rear view mirror is secured to the same mounting flag on the front door panel and in the same manner that is used to mount the standard equipment outside rear view mirrors.
- Front Door Control Modules - Vehicles that use the low current front door power switch configuration also have a front door control module for each front door. The front door control modules are concealed behind the door trim panels on the front door hardware module carrier.
- Front Door Power Switch Modules - Front door power switch modules are used in both primary system configurations: high current and low current. The outputs of the switches will identify the configuration type being used. In the high current configuration the switch outputs are hardwired directly to the power mirror, power window and power lock motors. In the low current configuration the switch outputs are hardwired to the driver or passenger front door control modules, which then control the high current outputs to the power mirror, power window and power lock motors.
- Power Folding Mirror Switch - The power folding mirror switch is used only on vehicles manufactured for certain export markets where power foldaway mirrors are required equipment. The power folding mirror switch is integral to the driver front door power switch module located on the driver side front door trim panel and is only serviced as a unit with the switch module.
- Power Mirror Switches - The power mirror system includes two selector switches and an adjuster switch that are located on the driver front door trim panel and are only serviced as an integral part of their respective driver front door power switch module.
- Power Outside Rear View Mirrors (1) - Power outside rear view mirror units are mounted to the mirror flag at the front belt line of each front door window opening. Many variations of both the driver and passenger mirror are available, depending upon both trim and other optional equipment in the vehicle.
In the low current switch configuration, the front door power switch modules and the front door control modules each contain a microcontroller and programming that allow them to communicate with each other using a Local Interface Network (LIN) data bus. The front door control modules and the automatic dimming inside rear view mirror each contain a microcontroller and programming that allow them to communicate with each other, with other electronic modules in the vehicle and with a diagnostic scan tool connected to the 16-way Data Link Connector (DLC) using the Controller Area Network (CAN) Interior High Speed (IHS) data bus.
hardwired circuitry connects the power mirror system components to each other through the electrical system of the vehicle. These hardwired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the power mirror system components through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
