Pinpoint Test G: One Or More (But Not All) Non-DIMMABLE Illumination Sources Are Inoperative

WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. G1 CHECK CIRCUIT CBP02 (GN) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: Inoperable Illumination Source
    • Key in ON position.
    • Measure the voltage between the inoperative illumination source, harness side and ground as follows:
      Component 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)
      Cigar lighter C370-B CBP02 (GN)
      Roof opening panel control switch C912-1 CBP02 (GN)
    • Is the voltage greater than 10 volts? 
    1. YES  : For a door lock control switch concern, INSTALL a new door lock control switch for the inoperative switch. REFER to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS article. TEST the system for normal operation.

      For a roof panel opening control switch concern, INSTALL a new roof panel opening control switch. REFER to ROOF OPENING PANEL article. TEST the system for normal operation.

      For a cigar lighter concern, go to  G2.

    2. NO  : Go to  G3.
  2. G2 CHECK CIRCUIT GD115 (BK/GY) FOR AN OPEN

    • Measure the resistance between the cigar lighter C370-C, circuit GD115 (BK/GY), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : INSTALL a new cigar lighter. TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  3. G3 CHECK CIRCUIT CBP02 (GN) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: SJB C2280e
    • Measure the resistance between the SJB connector, circuit CBP02 (GN), harness side and the inoperative illumination source, harness side as follows:
      Component SJB Connector-Pin Inoperative Component Connector-Pin Circuit
      LH door lock control switch (Fusion, Milan) C2280e-25 C505-2 CBP02 (GN)
      RH door lock control switch (Fusion, Milan) C2280e-25 C605-2 CBP02 (GN)
      Cigar lighter C2280b-28 C370-B CBP02 (GN)
      Roof opening panel switch C2280e-25 C912-1 CBP02 (GN)
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  G4.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  4. G4 CHECK FOR CORRECT SJB OPERATION 
    • Connect: Inoperable Illumination Source
    • 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 article. 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.
