    • Press the liftgate release button located on the liftgate.

    Does the liftgate latch release (manual liftgate) or the liftgate open (power liftgate)? 

    • Yes  : GO to V2 
    • No  : For vehicles equipped with a manual liftgate, GO to PINPOINT TEST N 

      For vehicles equipped with a power liftgate,

  3. V3 CHECK THE KEYLESS ENTRY REAR ANTENNA 
    • Ignition OFF.
    • Disconnect Keyless Entry Rear Antenna C4082  .
    • Measure:
      Positive Lead Measurement/Action Negative Lead

      C4082-2

    Is the resistance between 1 and 3 ohms? 

  4. V4 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE 
    • Disconnect RFA  Module C4392A  .
    • Ignition ON.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C4082-1  VOLTAGE Ground
      C4082-2  VOLTAGE Ground

    Is any voltage present? 

    • Yes  : REPAIR the affected circuit.
    • No  : GO to V5 
  5. V5 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C4082-1  OHM Ground
      C4082-2  OHM Ground

    Are the resistances greater than 10, 000 ohms? 

    • Yes  : GO to V6 
    • No  : REPAIR the affected circuit.
  6. V6 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR AN OPEN 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C4082-1  OHM C392A-22 
      C4082-2  OHM C392A-21 

    Are the resistances less than 3 ohms? 

    • Yes  : GO to V7 
    • No  : REPAIR the affected circuit.
  7. V7 CHECK FOR CORRECT RFA (REMOTE FUNCTION ACTUATOR) MODULE OPERATION 
    • Disconnect and inspect all RFA  module connectors.
    • Repair:
      • corrosion (install new connector or terminal - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the RFA  module connectors. 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 TSB. If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW the TSB  instructions. If no TSB  addresses this concern, INSTALL a new RFA  module.

      REFER to: REMOTE FUNCTION ACTUATOR (RFA) MODULE .

    • No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
