Inadvertent Power Relay

Range: ON/OFF
The inadvertent power relay output refers to the commanded state of the inadvertent power relay coil. ON displays when the BCM commands the inadvertent power relay coil to energize. The command allows the relay to power up the following components:
^ The courtesy lamp relay
^ The vanity lamps
^ The overhead reading lamps
^ The underhood lamps
^ The glove box lamp

OFF displays when the BCM does not command the inadvertent power relay coil to turn ON. The inadvertent power relay coil then does not allow current to the following components:
^ The courtesy lamp relay
^ The vanity lamps
^ The overhead reading lamps
^ The underhood lamp
^ The glove box lamp
