Pinpoint Test O: The Delayed Accessory Is Inoperative

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. O1 CHECK THE DOOR AJAR SWITCH OPERATION 
    • Open and close the front doors. Verify the interior lights turn on when the doors are open, and off when the doors are closed.
    • Do the interior lights operate normally?

    • No:  REFER to INTERIOR LIGHTING to diagnose the interior lighting and door ajar switches.
  2. O2 CHECK THE ACCESSORY DELAY RELAY 
    • Yes:  VERIFY SJB  fuse 41 (15A) (MKZ only) and circuit breaker 47 (30A) are OK. If OK, GO to  O3.

      If not OK, REFER to the appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation.

    • No:  INSTALL a new accessory delay relay. TEST the system for normal operation.
  3. O3 CHECK CIRCUIT CBP47 (GN/BU) FOR AN OPEN

    • 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 INSTALLATION . TEST the system for normal operation.
    • No:  The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
