- G1 VERIFY THE HEADLAMP OPERATION
- Key in ON position.
- Place the multifunction switch in the headlamps ON position.
- Place the multifunction switch in the HIGH BEAM and then LOW BEAM positions while observing the headlamps.
- Do the high beam and low beam headlamps operate correctly?
NOTE: Make sure the multifunction switch is in the LOW BEAM position.Yes: GO to G2.
No: GO to HEADLAMP SYMPTOM TABLE for correct diagnosis.
- G2 CHECK THE MULTIFUNCTION SWITCH
- Key in OFF position.
- Disconnect: Multifunction Switch C2080.
- Connect a fused (5A) jumper wire between the multifunction switch C2080-1, circuit 196 (DB/OG), harness side and the multifunction switch C2080-10, circuit 570 (BK/WH), harness side.
- Do the high beam headlamps illuminate?
Yes: INSTALL a new multifunction switch. REFER to STEERING COLUMN MULTIFUNCTION SWITCH . TEST the system for normal operation.
No: REMOVE the jumper wire. GO to G3.
- G3 CHECK CIRCUIT 196 (DB/OG) FOR AN OPEN

- Is the resistance less than 5 ohms?
Yes: GO to G4.
No: REPAIR the circuit. TEST the system for normal operation.
- G4 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 SMART JUNCTION BOX (SJB) . TEST the system for normal operation.
