Pinpoint Test D: The Puddle Lamps Are Inoperative

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
  1. D1 CHECK CIRCUIT 2010 (YE/RD) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: Memory Mirror C516 (LH) or C625 (RH).
    • Disconnect: Non-Memory Mirror C522 (LH) or C622 (RH).
    • Open any door.
    • Measure the voltage between the inoperative puddle lamp connector, circuit 2010 (YE/RD), harness side and ground as follows:
      VOLTAGE CHECK

      Description Connector-Pin Circuit
      With Memory Mirrors 
      LH mirror C516-8 2010
      (YE/RD)
      RH mirror C625-8 2010
      (YE/RD)
      Without Memory Mirrors 
      LH mirror C522-4 2010
      (YE/RD)
      RH mirror C622-4 2010
      (YE/RD)

    • Is the voltage greater than 10 volts? 

    Yes:  GO to  D2.

    No:  GO to  D3.

  2. D2 CHECK CIRCUIT 1205 (BK) FOR AN OPEN 
    • Key in OFF position.
    • Measure the resistance between the inoperative puddle lamp connector, circuit 1205 (BK), harness side and ground as follows:
      RESISTANCE CHECK

      Description Connector-Pin Circuit
      With Memory Mirrors 
      LH mirror C516-15 1205 (BK)
      RH mirror C625-15 1205 (BK)
      Without Memory Mirrors 
      LH mirror C522-6 1205 (BK)
      RH mirror C622-6 1205 (BK)
    • Is the resistance less than 5 ohms? 

    Yes:  INSTALL a new mirror. TEST the system for normal operation.

    No:  REPAIR the circuit. TEST the system for normal operation.

  3. D3 CHECK CIRCUIT 2010 (YE/RD) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: SJB C2280e.
    • Measure the resistance between the SJB C2280e-12, circuit 2010 (YE/RD) and the inoperative puddle lamp as follows:
      RESISTANCE CHECK

      Description Connector-Pin Circuit
      With Memory Mirrors 
      LH mirror C516-8 2010
      (YE/RD)
      RH mirror C625-8 2010
      (YE/RD)
      Without Memory Mirrors 
      LH mirror C522-4 2010
      (YE/RD)
      RH mirror C622-4 2010
      (YE/RD)

    • Is the resistance less than 5 ohms? 

    Yes:  GO to  D4.

    No:  REPAIR the circuit. TEST the system for normal operation.

  4. D4 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all SJB connectors.
    • Check for:
      • corrosion
      • pushed-out pins
    • Connect all SJB connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 

    Yes:  INSTALL a new SJB. REFER to REMOVAL AND INSTALLATION . TEST the system for normal operation.

    No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
