Wireless Door Lock Control Receiver
- Remove wireless door lock control receiver. See WIRELESS DOOR LOCK CONTROL RECEIVER under REMOVAL & INSTALLATION. Turn ignition off. Disconnect 5-pin electrical harness connector from wireless door lock control receiver.
- Using a DVOM on terminal side of 5-pin electrical harness connector, measure continuity between harness connector terminal No. 1 (White/Black wire) and good vehicle ground point. See Fig 1. Continuity should be present. Next, measure voltage between harness connector terminal No. 5 (Red wire) and good vehicle ground point. Battery voltage should be present. If circuits are as specified, go to next step. If circuits are not as specified, repair power and/or ground circuit as necessary. See POWER DOOR LOCKS
in SYSTEM WIRING DIAGRAMS article.
- Reconnect 5-pin electrical harness connector to wireless door lock control receiver. Ensure key is NOT in ignition switch, ignition is off and all doors are closed. Using an oscilloscope, backprobe between 5-pin wireless door lock control receiver electrical harness connector terminal No. 2 (Blue/White wire) and good vehicle ground point while activating any button on remote transmitter. See Fig 1. Voltage should change from below one volt to about 6-7 volts and back to below one volt when any button is cycled OFF/ON/OFF. If voltage changes as specified, go to next step. If voltage does not change as specified, repair circuit as required. See POWER DOOR LOCKS
in SYSTEM WIRING DIAGRAMS article.
- With ignition switch off and key removed from ignition switch, backprobe wire side of 5-pin electrical harness connector with DVOM connected between terminal No. 5 (Pink/Blue wire) and good vehicle ground point with remote transmitter off. See Fig 1. Voltage should be 10-14 volts. If voltage is as specified, replace wireless door lock control receiver. See WIRELESS DOOR LOCK CONTROL RECEIVER under REMOVAL & INSTALLATION. If voltage is not as specified, repair power circuit. See POWER DOOR LOCKS
in SYSTEM WIRING DIAGRAMS article.
