Inadvertent Power

Battery positive voltage (B+) is applied at all times through the INDVERT Fuse to the switch side of inadvertent power relay. Battery positive voltage (B+) is also applied at all times through the MIRROR Fuse to the coil side of the inadvertent power relay. When the ignition switch is turned to the RUN position, the Body Control Module (PZM) will activate the inadvertent power relay by grounding the relay coil via CKT 247 (BRN). With the inadvertent power relay active, battery positive voltage (B+) is supplied via CKT 65 (PPL) to the engine compartment fuse/relay center INT LPS Fuse, CIG LTR 1 Fuse, and CIG LTR 2 Fuse. The PZM will deactivate the inadvertent power relay 10 minutes after the ignition switch is removed from RUN. With the ignition switch in OFF or ACCY, the PZM will also deactivate the inadvertent power relay 10 minutes after any of the following conditions occur:
^ Illuminated entry is activated.
^ Interior lamps switch turned on.
^ The rear compartment has been opened or closed.
^ Afterblow is activated.
