Pinpoint Test E: B10D9:11, B10D9:12, B10D9:31 Or B10D9:87

  1. E1 CHECK THE BACKUP TRANSCEIVER CIRCUITS FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: RFA  Module C2153D  .
    • Disconnect: Backup Transceiver C3371  .
    • Ignition ON.
    • Measure the voltage between the backup transceiver, harness side and ground as follows:
      Backup Transceiver Connector-Pin Circuit
      C3371-2  LPK32 (GN/BU)
      C3371-3  VPK32 (WH/BU)
      C3371-4  VPK33 (WH)
      C3371-5  RPK32 (YE/GY)

    Is any voltage present? 

    • Yes  : REPAIR the circuit in question.
    • No  : GO to E2  .
  2. E2 CHECK THE BACKUP TRANSCEIVER CIRCUITS FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Measure the resistance between the backup transceiver, harness side and ground as follows:
      Backup Transceiver Connector-Pin Circuit
      C3371-2  LPK32 (GN/BU)
      C3371-3  VPK32 (WH/BU)
      C3371-4  VPK33 (WH)
      C3371-5  RPK32 (YE/GY)

    Are the resistances greater than 10, 000 ohms? 

    • Yes  : GO to E3  .
    • No  : REPAIR the circuit in question.
  3. E3 CHECK THE BACKUP TRANSCEIVER CIRCUITS FOR AN OPEN 
    • Measure the resistance between the backup transceiver, harness side and RFA  module, harness side as follows:
      Backup Transceiver Connector-Pin Circuit RFA Module Connector-Pin
      C3371-2  LPK32 (GN/BU) C2153D-11 
      C3371-3  VPK32 (WH/BU) C2153D-13 
      C3371-4  VPK33 (WH) C2153D-12 
      C3371-5  RPK32 (YE/GY) C2153D-14 
      Fig 3: Measuring Resistance Between Backup Transceiver And RFA Module

    Are the resistances less than 3 ohms? 

    • Yes  : INSTALL a new backup transceiver. REFER to BACKUP TRANSCEIVER . TEST the system for normal operation.

      If the concern is still present, GO to E4  .

    • No  : REPAIR the circuit in question.
  4. E4 CHECK FOR CORRECT RFA MODULE OPERATION 
    • Disconnect and inspect all the RFA  module connectors.
    • Repair:
      • corrosion (install new connector or terminals - 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 correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    • Yes  : CHECK On-Line Automotive Service Information System (OASIS) for any applicable TSBs  . If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW TSB  instructions. If no TSBs  address this concern, INSTALL a new RFA  module. REFER to MULTIFUNCTION ELECTRONIC MODULES .
    • 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.
