Power Door Locks



Diagnosis & Testing
Door Lock Motor

The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a scan tool and the proper Diagnostic Procedures manual. The scan tool can provide confirmation that the PCI data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the PCI data bus, and that the power lock motors are being sent the proper hard wired outputs by the relays for them to perform their power lock system functions.

The lock mechanisms are actuated by a reversible electric motor mounted within each door. The power lock motors are integral to the door latch units. The power lock motors cannot be adjusted or repaired and, if inoperative or damaged, the door latch unit must be replaced.

  1. Make certain the battery is in normal condition and the fuses powering the RKE module are not blown before continuing to test the circuits.
  2.  
  3. To determine which motor is inoperative, check each individual door electrical lock and unlock function or disconnect the motor connectors one at a time, while operating the door lock switch.
  4.  
  5. In the event that none of the motors work, the problem may be caused by a shorted motor, a bad Switch, or a bad relay internal to the RKE module. Disconnecting a defective motor will allow the others to work.
  6.  
  7. To test an individual door lock motor, disconnect the electrical connector from the motor.
  8.  
  9. To lock the door, connect a 12 volt power source to one pin of the lock motor and a ground wire to the other pin.
  10.  
  11. To unlock the door, reverse the wire connections at the motor pin terminals.
  12.  
  13. If these results are NOT obtained, replace the motor.

  1. Remove the power door lock switch.
  2.  
  3. Using an ohmmeter, refer to the Door Lock Switch Test Table to determine if the switch resistance is correct in the Lock and Unlock switch positions.
