- Unlock driver's door. Using voltmeter, backprobe BCM 20-pin connector. Check for a voltage pulse at terminal No. 4, while pressing UNLOCK button on transmitter. See Fig 1 . If there is no voltage pulse, replace BCM. See REMOVAL & INSTALLATION . If voltage pulse is present, repair circuit between BCM and driver's door lock motor. See WIRING DIAGRAMS .
