    • Press the liftgate release button twice on a valid programmed passive key.

    Does the liftgate power open? 

    Yes  GO to  W2
    No  GO to Pinpoint Test R 

  2. W2 CHECK THE LIFTGATE RELEASE SWITCH INPUT

    • Close the liftgate.

    • Ignition ON.

    • Unlock the doors using the door lock control switch.

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

    Does the liftgate power open? 

    Yes  GO to  W3
    No  REFER to: Body Closures .

  3. W3 CHECK THE KEYLESS ENTRY REAR ANTENNA

    • Ignition OFF.

    • Disconnect: Keyless Entry Rear Antenna C4332.

    • Measure:

    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

    • Disconnect: BCM C2280D.

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead

      		 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 service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCM. Refer to BODY CONTROL MODULE (BCM) .
    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.
