Pinpoint Test B: The Door Locks Operate One Way Only

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. B1 CHECK THE DOOR LOCK CONTROL SWITCHES 
    • Key in OFF position.
    • Disconnect: RH Door Lock Control Switch C629.
    • Disconnect: LH Door Lock Control Switch C508.
    • Disconnect: Rear Door Lock Control Switch C4121 (if equipped).
    • Carry out the door lock control switch component test for the LH, RH, and rear (if equipped) door lock control switches. Refer to COMPONENT TESTING article for component testing.
    • Are the door lock control switches OK? 
  2. B2 CHECK THE RH DOOR LOCK CONTROL SWITCH CIRCUIT 57 (BK) FOR AN OPEN 
    • Measure the resistance between the RH door lock control switch C629-10, circuit 57 (BK), harness side and ground; and between the RH door lock control switch C629-6, circuit 57 (BK), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : On a 2-door lock control switch system with an inoperative door lock control LOCK button, REPAIR circuits 123 (RD) or 1296 (OG/BK) as necessary. TEST the system for normal operation.

      On a 2-door lock control switch system with an inoperative door lock control UNLOCK button, REPAIR circuits 124 (BN) or 1297 (YE/RD) as necessary. TEST the system for normal operation.

      If equipped with a 3-door lock control switch system, GO to B3.

    • No  : REPAIR the circuit. TEST the system for normal operation.
  3. B3 CHECK CIRCUITS 123 (RD), 1296 (OG/BK), 124 (BN), AND 1297 (YE/RD) FOR AN OPEN OR SHORT TO GROUND 
    • If a door lock control switch LOCK button is inoperative, measure the resistance between the LH door lock control switch C508-5, circuit 1296 (OG/BK), harness side and the RH door lock control switch C629-9, circuit 123 (RD), harness side; and between the LH door lock control switch C508-5, circuit 1296 (OG/BK), harness side and ground.

    • Is the resistance less than 5 ohms between the RH and LH door lock control switches, and greater than 10,000 ohms between the LH door lock control switch and ground? 
    • Yes  : REPAIR circuits 123 (RD) (inoperative LOCK button) or 124 (BN) (inoperative UNLOCK button) between the LH and rear door lock control switches. TEST the system for normal operation.
    • No  : If the door lock control LOCK button is inoperative, REPAIR circuits 123 (RD) or 1296 (OG/BK). TEST the system for normal operation.

    If the door lock control UNLOCK button is inoperative, REPAIR circuits 124 (BN) or 1297 (YE/RD). TEST the system for normal operation.
