Pinpoint Test L: The Delayed Accessory Is Inoperative

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

L1 CHECK FOR CORRECT OPERATION OF THE INTERIOR LIGHTS
- 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 L2.

No : VERIFY SJB fuse 3 (15A) and fuse 12 (7.5A) are OK. If OK, REFER to INTERIOR LIGHTING to diagnose the interior lighting and door ajar switches.
L2 CHECK CIRCUIT SBB01 (RD) FOR VOLTAGE
- Disconnect: SJB C2280F.
- Key in ON position.
- Measure the voltage between SJB C2280F-2, circuit SBB01 (RD), harness side and ground.

- Is the voltage greater than 10 volts?
Yes : GO to L3.

No : VERIFY BJB fuse 1 (80A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
L3 CHECK CIRCUIT CPW30 (GY/YE) FOR AN OPEN
- Disconnect: LH Front Window Control Switch C504A (Fusion, Milan) or C504B (Zephyr).
- For Fusion or Milan, measure the resistance between LH front window control switch C504A-2, circuit CPW30 (GY/YE), harness side and SJB C2280E-4, circuit CPW30 (GY/YE), harness side.

- Is the resistance less than 5 ohms?
Yes : GO to L4.

No : REPAIR the circuit. TEST the system for normal operation.
L4 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 CONTROL MODULES for the removal and installation procedure. 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.
