B3824
DTC B3824
CIRCUIT DESCRIPTION
Battery positive voltage is supplied to the right rear power window switch and the up and down relays through the window lockout signal circuit. If the window lockout function is disabled, the body control module (BCM) supplies battery positive voltage to the switch and relays and the right window operates normally. If the window lockout function is enabled, the BCM will not supply battery positive voltage to the switch and relays and the right rear window will be inoperative unless it is operated from the driver power window switch.
