- Using voltmeter, backprobe BCM 20-pin connector. Check for a voltage pulse at terminals No. 10 while pressing transmitter UNLOCK button. See Fig 1 . BCM is located on junction block behind lower left corner of instrument panel. If there is no voltage pulse, replace BCM. See REMOVAL & INSTALLATION. If voltage pulse is present, repair harness between appropriate BCM terminal and door lock motor. See WIRING DIAGRAM.
