System Operation
The underhood fuse block provides battery positive voltage to the Inadvertent Power relay coil through the MIRROR fuse. The left underhood fuse block provides battery positive voltage to the Inadvertent Power relay switch through the INADVERT fuse. When the ignition switch is turned to the RUN position, the Body Control Module (BCM) will activate the inadvertent power relay by grounding the relay coil. When the inadvertent power relay is active, battery positive voltage is supplied to the underhood fuse block INT LPS Fuse, CIG LTR 1 Fuse, and CIG LTR 2 Fuse. The BCM will deactivate the inadvertent power relay ten minutes after the ignition switch is removed from the RUN position. With the ignition switch in the OFF or ACCY position, the BCM will also deactivate the inadvertent power relay ten minutes after any of the following conditions occur:^ The illuminated entry is activated.
^ The interior lamp switch is turned ON.
^ The rear compartment has been opened or closed.
^ The afterblow is activated.
If the ignition switch is turned to any position other than OFF, or if a lamp switch is activated during this 10 minute period the timer will reset for another 10 minutes. This time is reduced to 3 minutes until the vehicle mileage is more than 22.5 km (14 mi) +/- 2.2 km (1.4 mi).
