Turn ignition off. Unplug 10-pin HVAC connector, located near plenum. Unplug BCM, located above right kick panel. With DRB in voltmeter mode, probe Dark Blue/Red wire at Black BCM connector. If voltage is not higher than 10 volts, go to next step. If voltage is higher than 10 volts, repair short to voltage on Dark Blue/Red wire. Perform VERIFICATION TEST.
With DRB in ohmmeter mode, probe Dark Blue/Red wire at Black BCM connector. If resistance is less than 5 ohms, repair short to ground on Dark Blue/Red wire. Perform VERIFICATION TEST. If resistance is not less than 5 ohms, replace BCM. Perform VERIFICATION TEST.
