- F1 VERIFY THE HIGH BEAM HEADLAMP OPERATION
- Key in ON position.
- Place the headlamp switch in the HEADLAMPS ON position.
- Place the multifunction switch in the HIGH BEAM position while observing the headlamps.
- Do the high beam headlamps illuminate?
Yes : GO to F2.
No : GO to PINPOINT TEST B .
- F2 CHECK THE MULTIFUNCTION SWITCH
- Key in OFF position.
- Disconnect: Multifunction Switch C202.
- Connect a fused (5A) jumper wire between the multifunction switch C202-4, circuit CLF27 (GN/BN), harness side and the multifunction switch C202-8, circuit GD116 (BK/VT), harness side.
- Do the high beam headlamps illuminate?
Yes : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
No : REMOVE the jumper wire. GO to F3.
- F3 CHECK CIRCUIT CLF27 (GN/BN) FOR AN OPEN
- Disconnect: SJB C2280d.
- Measure the resistance between the multifunction switch C202-4, circuit CLF27 (GN/BN), harness side and the SJB C2280d-25, circuit CLF27 (GN/BN), harness side.
- Is the resistance less than 5 ohms?
Yes : GO to F4.
No : REPAIR the circuit. TEST the system for normal operation.
- F4 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.
