Pinpoint Test P: The Delayed Accessory Is Inoperative

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 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.

P1 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?
- Yes : Go to P2.
- No : Refer to INTERIOR LIGHTING -- FUSION, MILAN & MKZ article to diagnose the interior lighting and door ajar switches.
P2 CHECK THE ACCESSORY DELAY RELAY
- Disconnect: Accessory Delay Relay.
- Carry out the accessory delay relay component test. Refer to ENGINE CONTROLS - COMPONENT TESTING -- FUSION, MILAN & MKZ (EXCEPT HYBRID) article for component testing.
- Did the delayed accessory relay pass the component test?
- Yes : VERIFY SJB fuse 41 (15A) (MKZ only) and circuit breaker 47 (30A) are OK. If OK, Go to P3. If not OK, Refer to the 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.
P3 CHECK THE MASTER WINDOW CONTROL SWITCH POWER CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: SJB C2280D.
- Disconnect: Master Window Control Switch C537A (Fusion, Milan, if RH front window is not equipped with one-touch up/down) or C535B (MKZ and/or Fusion/Milan if RH front window is equipped with one-touch up/down).
- Measure the resistance between master window control switch C537A-2 or C535B-3, circuit CBP47 (GN/BU), harness side and SJB C2280D-32, circuit CBP47 (GN/BU), harness side.

- Is the resistance less than 5 ohms?
- Yes : Go to P4.
- No : REPAIR the circuit. TEST the system for normal operation.
P4 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 MULTIFUNCTION ELECTRONIC MODULES -- FUSION, MILAN & MKZ article. 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.
