When the headlamp switch is placed in the HEADLAMPS ON position and the multifunction switch in the HIGH BEAM position, the multifunction switch routes voltage to the central junction box (CJB) fuse 30 (15A) through circuit 632 (GY/OG). Voltage is then routed to the high beams through circuit 12 (LG/BK).
This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Multifunction switch
