Doors Will Not Unlock With Transmitter

Using voltmeter, backprobe BCM 20-pin connector. Check for a voltage pulse at terminal No. 4 while pressing transmitter UNLOCK button. See Fig 1 . If there is no voltage pulse, replace BCM. See REMOVAL & INSTALLATION . If voltage pulse is present, repair harness between BCM terminal No. 4 and left door lock motor. See WIRING DIAGRAMS . Go to next step.
