Timer Function

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

When IPDM E/R turns rear window defogger relay ON, BCM transmits rear window defogger control signal to IPDM E/R, and rear window defogger relay is turned ON for approximately 15 minutes.
The timer is cancelled if the rear window defogger switch is pressed again during timer operation. BCM stops the output of rear window defogger switch signal. The same action occurs during timer operation if the power switch is OFF.
