Heated Glass Element Switch: Description and Operation
Operation
OPERATION
An amber indicator will illuminate when the rear window defogger switch is activated. When activated, the switch sends a request signal to the cabin
compartment node (CCN), which sends a message to the totally integrated power module (TIPM) to energize the internal EBL high side driver to
provide battery current to the rear window defogger grid lines and when equipped, to the heated side view mirrors.
NOTE: The EBL system turns off automatically after 10 minutes of initial operation. Each following activation cycle of the EBL system will last
5 minutes.
The EBL system will be automatically turned off after an initial programmed time interval of about 10 minutes as long as the ignition switch is in RUN.
After the initial time interval has expired, if the rear window defogger system is turned on again during the same ignition cycle, the EBL system will
automatically turn off after about 5 minutes. The EBL system will automatically shut off if the ignition switch is turned to any position other than RUN,
or it can be turned off manually by pressing the rear window defogger switch a second time.
The rear window defogger switch is diagnosed using a scan tool.
The rear window defogger switch and the rear window defogger indicator cannot be repaired and the switch must be replaced if found inoperative or
damaged.
