Pinpoint Test F: A Single Illumination Source Is Inoperative - Non-DIMMABLE Illumination Source

CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
  1. F1 CHECK CIRCUIT CBP02 (GN) FOR VOLTAGE 
    • Disconnect: Inoperable Illumination Source
    • Key in ON position.
    • Measure the voltage between the inoperable illumination source harness side and ground as follows:
      Illumination Source Connector-Pin Circuit
      LH door lock control switch (Fusion, Milan) C505-2 CBP02 (GN)
      RH door lock control switch (Fusion, Milan) C605-2 CBP02 (GN)
      Ashtray C370-B CBP02 (GN)
      Roof opening panel switch C912-1 CBP02 (GN)
    • Is the voltage greater than 10 volts? 
    1. YES  : For door lock control switch(es), INSTALL a new door lock control switch. REFER to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS .

      For the ashtray, go to  F3 .

      For the roof opening panel, go to  F4 .

    2. NO  : Go to  F2.
  2. F2 CHECK CIRCUIT CBP02 (GN) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: SJB C2280e
    • Measure the resistance between the SJB C2280e-25, circuit CBP02 (GN) harness side; and the inoperable illumination source as follows:
      Illumination Source Connector-Pin Circuit
      LH door lock control switch (Fusion, Milan) C505-2 CBP02 (GN)
      RH door lock control switch (Fusion, Milan) C605-2 CBP02 (GN)
      Ashtray C370-B CBP02 (GN)
      Roof opening panel switch C912-1 CBP02 (GN)
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  F7.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  3. F3 CHECK CIRCUIT GD115 (BK/GY) FOR AN OPEN

    • Measure the resistance between the ashtray C370-C, circuit GD115 (BK/GY), harness side and ground.
    • Is the resistance less than 5 ohms between the ashtray and ground? 
    1. YES  : INSTALL a new illumination source. TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  4. F4 CHECK CIRCUIT CPR39 (VT/WH) FOR AN OPEN 
    • Disconnect: Roof Opening Panel Module C921
      • Fig 2: Checking Circuit CPR39 (VT/WH) For Open
      GF0030366Courtesy of FORD MOTOR CO.
    • Measure the resistance between the roof opening panel switch C912-4, circuit CPR39 (VT/WH), harness side and the roof opening panel module C921-11, circuit CPR39 (VT/WH), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  F5.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  5. F5 CHECK CIRCUIT GD139 (BK/YE) FOR AN OPEN 
      Fig 3: Checking Circuit GD139 (BK/YE) For Open
      GF0030367Courtesy of FORD MOTOR CO.
    • Measure the resistance between the roof opening panel module C921-4, circuit GD139 (BK/YE), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  F6.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  6. F6 CHECK FOR CORRECT ROOF OPENING PANEL MODULE OPERATION 
    • Disconnect the roof opening panel module connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the roof opening panel module connector and make sure it seats correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. YES  : INSTALL a new roof opening panel module. REFER to ROOF OPENING PANEL . TEST the system for normal operation.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
  7. F7 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect all the SJB connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. YES  : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
