Power Door Lock Actuator: Testing and Inspection
DOOR LOCK MOTOR
The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a DRBIII(R) scan tool and the proper
Diagnostic Procedures manual. The DRBIII(R) 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 door modules for them to perform their power lock system functions.
Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of
wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
1. Make certain battery is in normal condition and fuses powering the RKE module aren't blown before circuits are tested.
2. To determine which motor is faulty, check each individual door for electrical lock and unlock or disconnect the motor connectors one at a time,
while operating the door lock switch.
3. In the event that none of the motors work, the problem maybe 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.
4. To test an individual door lock motor, disconnect the electrical connector from the motor.
5. 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.
6. To unlock the door, reverse the wire connections at the motor pin terminals.
7. If these results are NOT obtained, replace the motor.
