Door Locks Do Not Operate Using Remote Transmitter
- Turn ignition off. Reprogram remote transmitter. See REMOTE TRANSMITTER
under PROGRAMMING. After reprogramming, if remote transmitter and door lock control module still do not respond correctly, go to next step. After reprogramming, if remote transmitter and door lock control module respond correctly, test entire system for normal operation.
- Replace remote transmitter batteries. Reprogram remote transmitter. See REMOTE TRANSMITTER
under PROGRAMMING. After battery replacement and reprogramming, if remote transmitter and door lock control module still do not respond correctly, go to next step. After battery replacement and reprogramming, if remote transmitter and door lock control module respond correctly, test entire system for normal operation.
- Using a known good transmitter, reprogram remote transmitter. See REMOTE TRANSMITTER
under PROGRAMMING. After reprogramming known good transmitter, if remote transmitter and door lock control module still do not respond correctly, go to next step. After reprogramming known good transmitter, replace original remote transmitter. Reprogram NEW remote transmitter and test entire system for normal operation.
- Disconnect door lock control module connectors C335 and C336. Turn ignition on. Measure voltage between ground and door lock control module connector C336 terminals No. 2 and 16. See Fig 3
. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair open in Yellow/Black wire, then retest system.
- Measure voltage between ground and door lock control module connector C335 terminal No. 22. See Fig 2
. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair open in Black/White wire, then retest system.
- Turn ignition off. Measure resistance between ground and door lock control module connector C335 terminal No. 8. Measure resistance between ground and door lock control module connector C335 terminal No. 21. Measure resistance between ground and door lock control module connector C335 terminal No. 23. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open Black/Light Blue wire, then retest system.
- Reconnect door lock control module connectors. Measure voltage by backprobing door lock control module connector C336 terminal No. 3 and ground while pressing remote transmitter UNLOCK button twice. Measure voltage by backprobing door lock control module connector C336 terminal No. 17 and ground while pressing remote transmitter UNLOCK button twice. If voltage is greater than 10 volts while UNLOCK button is pressed, repair Pink/Orange wire, then retest system. If voltage is less than 10 volts while UNLOCK button is pressed, go to next step.
- Measure voltage by backprobing door lock control module connector C336 terminal No. 4 and ground while pressing remote transmitter UNLOCK button. If voltage is greater than 10 volts while UNLOCK button is pressed, repair Red/Orange wire, then retest system. If voltage is less than 10 volts while UNLOCK button is pressed, go to next step.
- Measure voltage by backprobing door lock control module connector C336 terminal No. 5 and ground while pressing remote transmitter LOCK button. Measure voltage by backprobing door lock control module connector C336 terminal No. 18 and ground while pressing remote transmitter LOCK button. If voltage is greater than 10 volts while LOCK button is pressed, repair open in Pink/Black wire, then retest system. If voltage is less than 10 volts while LOCK button is pressed, go to next step.
- Measure voltage by backprobing door lock control module connector C336 terminal No. 6 and ground while pressing remote transmitter LOCK button. Measure voltage by backprobing door lock control module connector C336 terminal No. 19 and ground while pressing remote transmitter LOCK button. If voltage is greater than 10 volts while LOCK button is pressed, repair Yellow/Black wire, then retest system. If voltage is less than 10 volts while LOCK button is pressed, replace door lock control module, then retest system.
