Timer Function
- The BCM transmits the rear window defogger control signal to the IPDM E/R for approximately 15 minutes when the rear window defogger switch turns ON while power switch is ON. Then the IPDM E/R activates the rear window defogger and the door mirror defoggers (when equipped) by closing the rear window defogger relay.
- The timer is cancelled if the rear window defogger switch is pressed again during timer operation. When the timer is cancelled, the BCM stops the output of rear window defogger control signal, causing the IPDM-ER to disengage the rear window defogger relay. The same action occurs during timer operation if the power switch is turned OFF.
