    Is the resistance between 1 and 3 ohms? 

    Yes  GO to  V4
    No  INSTALL a new keyless entry rear antenna. REFER to: Keyless Entry Rear Antenna  .

  4. V4 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  V6
    No  REPAIR the circuit in question.

  6. V6 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR AN OPEN

    Are the resistances less than 3 ohms? 

    Yes  GO to  V7
    No  REPAIR the circuit in question.

  7. V7 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, Refer to .
    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.
