Test F: Power Door Locks Do Not Function Properly

  1. Lock and unlock the doors several times using the door lock switch at each door. Do all the doors lock/unlock properly, and do all the door lock switches operate properly? If yes, go to step  12 . If no and no locks work, go to TEST B: ELECTRONIC DOOR LOCK CONTROL SYSTEM INOPERATIVE  . If no and one or more locks do not work, go to next step. If no and one door lock switch does not work, go to step  8 . If no and locks will only lock or unlock, go to next step.
  2. Turn key to OFF position. Disconnect the inoperative power lock actuator connector located in the left hand front door, right hand front door, body side door, or liftgate. Measure the voltage on the lock signal wire between the power lock actuator connector and ground, while pressing the lock side of the door lock switch. See TESTING DOOR LOCK ACTUATOR  . Measure the voltage on the unlock signal wire between the power lock actuator connector and ground, while pressing the unlock side of the door lock switch. See TESTING DOOR LOCK ACTUATOR  . Is the voltage greater than 10 volts in each case? If yes, replace the power lock actuator. POWER DOOR LOCK ACTUATOR  under REMOVAL & INSTALLATION. If no (voltage on lock wire incorrect), go to next step. If no (voltage on unlock wire incorrect), go to step  5 .
  3. Turn key to OFF position. Disconnect all the power lock actuator connectors. Disconnect the 8-terminal electronic door lock control processor connector located behind the left hand instrument panel lower cover. Measure the resistance of the lock signal wire between the 8-terminal electronic door lock control processor connector and ground. Measure the resistance of the lock signal wire between the 8-terminal electronic door lock control processor connector and the inoperative power lock actuator connector. See CONNECTOR IDENTIFICATION  . Is the resistance greater than 10,000 ohms between the electronic door lock control processor and ground, and less than 5 ohms between the electronic door lock control processor and the power lock actuator? If yes, go to next step. If no, service the lock signal wire. See WIRING DIAGRAMS  .
  4. Reconnect the electronic door lock control processor connector. Measure the voltage of the Green/Yellow wire lock all signal wire between the 8-terminal electronic door lock control processor connector and ground, while pressing the lock side of the door lock switch. See CONNECTOR IDENTIFICATION  . Is the voltage greater than 10 volts? If yes, go to step  7 . If no, replace the electronic door lock control processor. See ELECTRONIC DOOR LOCK CONTROL PROCESSOR  under REMOVAL & INSTALLATION.
  5. Turn key to OFF position. Disconnect the inoperative power lock actuator connector. Disconnect the 8-terminal electronic door lock control processor connector. Measure the resistance of the unlock signal wire between the 8-terminal electronic door lock control processor connector and ground. See TESTING DOOR LOCK ACTUATOR  . Measure the resistance of the unlock signal wire between the 8-terminal electronic door lock control processor connector and the power lock actuator connector. Is the resistance greater than 10,000 ohms between the electronic door lock control processor and ground, and less than 5 ohms between the electronic door lock control processor and the power lock actuator? If yes, go to next step. If no, service the unlock signal wire. See WIRING DIAGRAMS  .

  6. Reconnect the 8-terminal electronic door lock control processor connector. Measure the voltage on the unlock signal wire between the 8-terminal electronic door lock control processor connector and ground, while pressing the unlock side of the door lock switch. See DOOR LOCK SWITCH IN UNLOCK POSITION  . Is the voltage greater than 10 volts? If yes, go to next step. If no, replace the electronic door lock control processor. See ELECTRONIC DOOR LOCK CONTROL PROCESSOR  under REMOVAL & INSTALLATION.
  7. Measure the voltage on the following wires between the 8-terminal electronic door lock control processor connector and ground, while pressing the door lock switch as directed. Do not disconnect the 8-terminal electronic door lock control processor connector. Is each voltage okay? If yes, the power lock actuator circuit(s) and the power lock actuator(s) are okay. If no, replace the electronic door lock control processor. See ELECTRONIC DOOR LOCK CONTROL PROCESSOR  under REMOVAL & INSTALLATION.

  8. Turn key to OFF position. Disconnect the inoperative door lock switch connector located in the left hand front door or the right hand front door. Measure the resistance between the Green/White wire terminal and the Black wire terminal on the door lock switch while pressing the lock side of the switch. Measure the resistance between the Green/Orange wire terminal and the Black wire terminal on the door lock switch while pressing the unlock side of the switch. Are the resistances less than 5 ohms with the switch depressed and greater than 10,000 ohms with the switch released? If yes, go to next step. If no, replace the door lock switch.
