Pinpoint Test W : The Tailgate Passive Entry Feature Is Inoperative

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

  1. W1 CHECK THE LIFTGATE RELEASE SWITCH INPUT

    • Close the tailgate.

    • Ignition ON.

    • Unlock the doors using the door lock control switch.

    • Press the tailgate release button located at the rear of the vehicle.

    Does the tailgate latch release? 

    Yes  GO to  W2
    No  GO to Pinpoint Test N 

  2. W2 CHECK THE RKE (REMOTE KEYLESS ENTRY) OPERATION

    • Ignition OFF.

    • Close the tailgate.

    • Press the tailgate release button twice on a key.

    Does the tailgate latch release? 

    Yes  GO to  W3
    No  GO to Pinpoint Test R 

  3. W3 CHECK THE KEYLESS ENTRY REAR ANTENNA

    • Ignition OFF.

    • Disconnect Keyless Entry Rear Antenna C4321 .

    • Measure:
      Positive Lead Measurement / Action Negative Lead

      C4321, pin 2, component side

    Is the resistance between 1 and 3 ohms? 

    Yes  GO to  W4
    No  INSTALL a new keyless entry rear antenna. Refer to: Keyless Entry Rear Antenna .

  4. W4 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2280D-30
      GFD177136Courtesy of FORD MOTOR COMPANY
      		 Ground
      C2280D-32
      GFD177136Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is any voltage present? 

    Yes  REPAIR the circuit in question.
    No  GO to  W5

  5. W5 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO GROUND

    • Ignition OFF.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2280D-30
      GFD177137Courtesy of FORD MOTOR COMPANY
      		 Ground
      C2280D-32

      		 Ground

    Are the resistances greater than 10, 000 ohms? 

    Yes  GO to  W6
    No  REPAIR the circuit in question.

  6. W6 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR AN OPEN

    Are the resistances less than 3 ohms? 

    Yes  GO to  W7
    No  REPAIR the circuit in question.

  7. W7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Disconnect and inspect all the BCM connectors.

    • Repair:

      • corrosion (install new connectors or terminals - clean module pins)
      • damaged or bent pins - install new terminals pins
      • pushed-out pins - install new pins as necessary

    • Reconnect the BCM connectors and make sure they seat and latch correctly.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to BCM Hardware Testing
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
