Pinpoint Test C: A Single Door Lock Is Inoperative

WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
  1. C1 CHECK CIRCUIT 1383 (RD) OR CIRCUIT 117 (PK/BK) FOR AN OPEN OR SHORT TO GROUND 
    • Disconnect: Smart Junction Box (SJB) C2280b.
    • Disconnect: Suspect Door Lock Actuator Connector.
    • If the driver side door lock actuator is inoperative, measure the resistance between the driver door lock actuator C525 pin 2, circuit 1383 (RD), harness side and ground; and between the driver door lock actuator C525 pin 2, circuit 1383 (RD), harness side and the smart junction box (SJB) C2280b pin 9, circuit 1383 (RD), harness side.

    • Is the resistance greater than 10,000 ohms between the door lock actuator connector and ground and less than 5 ohms between the door lock actuator and the SJB connector? 
    1. Yes  : GO to C2.
    2. No  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
  2. C2 CHECK CIRCUIT 1384 (LB) OR CIRCUIT 118 (PK/OG) FOR AN OPEN OR SHORT TO GROUND 
    • Disconnect: SJB C2280c.
    • If the driver side door lock actuator is inoperative, measure the resistance between the driver door lock actuator C525 pin 1, circuit 1384 (LB), harness side and ground; and between the driver door lock actuator C525 pin 1, circuit 1384 (LB), harness side and the SJB C2280c pin 7, circuit 1384 (LB), harness side.

    • Is the resistance greater than 10,000 ohms between the door lock actuator connector and ground and less than 5 ohms between the door lock actuator and the SJB connector? 
    1. Yes  : GO to C3.
    2. No  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
  3. C3 CHECK THE SUSPECT DOOR LOCK ACTUATOR OPERATION 
    • Connect a 5A fused jumper wire between the suspect door lock actuator connector pin 1, component side and the battery positive terminal; and between the suspect door lock actuator connector pin 2, component side and ground.

    • Does the door lock actuator operate correctly? 
    1. Yes  : GO to C4.
    2. No  : INSTALL a new door lock actuator. REFER to DOOR LOCK ACTUATOR . CLEAR the DTCs. REPEAT the self-test.
  4. C4 CHECK THE SJB FOR CORRECT OPERATION 
    • Disconnect all SJB connectors.
    • Check for:
      • Corrosion
      • Pushed-out pins
    • Connect all SJB connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. Yes  : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC CONTROL MODULES . CLEAR the DTCs. REPEAT the self-test.
    2. No  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
