Heated Mirrors - Description

DESCRIPTION






NOTE: MTC control shown. ATC control similar.

When equipped, the heated mirror system operates in concert with the rear window defogger system. The rear window defogger and heated mirror systems are controlled by a momentary push-button switch integral to the mode control knob located on the A/C-heater control (1) in the instrument panel. When the rear window defogger switch is pressed to the On position with the ignition switch in RUN, the switch sends a request signal over the Controller Area Network (CAN) bus to the Totally Integrated Power Module (TIPM) to energize the internal Electric Backlight (EBL) high side driver. When energized, the EBL high side driver provides battery current to the rear window defogger grid lines and to the heated side view mirrors. The heated side view mirrors help clear the mirror surfaces of fog or frost.

An amber indicator in the mode control knob will illuminate to indicate when the heated mirror system is turned on.

NOTE: The heated mirror system turns off automatically after ten minutes of initial operation. Each following activation cycle of the heated mirror system will last five minutes.

The heated mirror system will be automatically turned off after an initial programmed time interval of about ten minutes as long as the ignition switch is in RUN. After the initial time interval has expired, if the rear window defogger switch is pressed to the On position again during the same ignition cycle, the heated mirror system will automatically turn off after about five minutes. The heated mirror system will also turn off if the ignition switch is turned to any position other than RUN or by manually pressing the rear window defogger switch a second time.

Circuit protection for the heated mirror system is provided by fuse M35, located in the TIPM.
