    2.  
    3. With the scan tool, record and erase any Diagnostic Trouble Codes (DTC-s).
    4.  
    5. Turn the ignition OFF , wait 10 seconds, then turn the ignition ON .
    6.  
    7. Try to operate the door locks several times.

    Door Lock Motor

    Specific to:

    Jeep Compass 2007-2009

    Jeep Patriot 2007-2009

    The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a scan tool and the proper Diagnostic information. Refer to the appropriate wiring information.

    1. Make certain the battery is in normal condition and the fuses powering the RKE module are not blown before the circuits are tested.
    2.  
    3. To determine which motor is inoperative, check each individual door for electrical lock and unlock functions 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 that is internal to the RKE module.
      NOTE
      Disconnecting a defective motor may allow the others to work.

    6.  
    7. To test an individual door lock motor:
      1. Disconnect the electrical connector from the motor.
      2.  
      3. 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.
      4.  
      5. To unlock the door, reverse the wire connections at the motor pin terminals.
      6.  
      7. If the above results are not obtained, replace the door latch/motor assembly.
