Pinpoint Test B: The High Beams Are 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.

B1 CHECK THE MULTIFUNCTION SWITCH
- Key in ON position.
- Enter the following diagnostic mode on the scan tool: SJB Multifunction Switch PID.
- Monitor the SJB multifunction switch PID while placing the multifunction switch in the HIGH BEAM and LOW BEAM positions.
- Does the PID agree with the multifunction switch positions?
Yes : GO to B5.

No : GO to B2.
B2 CHECK THE MULTIFUNCTION SWITCH
- Key in OFF position.
- Disconnect: Multifunction Switch C202.
- Carry out the multifunction switch component test. Refer to COMPONENT TESTING .
- Is the multifunction switch OK?
Yes : GO to B3.

No : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES . CLEAR the DTCs. REPEAT the self-test.
B3 CHECK CIRCUIT GD116 (BK/VT) FOR AN OPEN
- Measure the resistance between the multifunction switch C202-8, circuit GD116 (BK/VT), harness side and ground.

- Is the resistance less than 5 ohms?
Yes : GO to B4.

No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
B4 CHECK CIRCUIT CLF17 (WH/OG) FOR AN OPEN
- Disconnect: SJB C2280d.
- Measure the resistance between the multifunction switch C202-6, circuit CLF17 (WH/OG), harness side and the SJB C2280d-15, circuit CLF17 (WH/OG), harness side.

- Is the resistance less than 5 ohms?
Yes : GO to B6.

No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
B5 CHECK CIRCUIT CLS08 (VT/GN) FOR AN OPEN
- Disconnect: LH Headlamp C1021.
- Disconnect: SJB 2280a.
- Measure the resistance between the LH headlamp C1021-7, circuit CLS08 (VT/GN), harness side and the SJB C2280a-30, circuit CLS08 (VT/GN), harness side.

- Is the resistance less than 5 ohms?
Yes : GO to B6.

No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
B6 CHECK FOR CORRECT SJB OPERATION
- Disconnect all the SJB connectors.
- Check for:
  - Corrosion
  - 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?
Yes : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC CONTROL MODULES . 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. CLEAR the DTCs. REPEAT the self-test.
