PINPOINT TEST C: THE HIGH BEAMS ARE INOPERATIVETest C1:
Test C2-C4:
Normal Operation
The multifunction switch receives power from circuit 13 (RD/BK) when the headlamp switch is in the headlamps ON position. When the multifunction switch is placed in the high beam position, voltage is routed to the high beam relay through circuit 697 (BN). When the high beam relay receives battery voltage from circuit 697 (BN), the high beam relay is energized. Battery voltage received from circuit 212 (DB) is then routed to circuit 632 (GY/OG), which then proceeds to circuit 12 (LG/BK) via BJB 46 (20A). Voltage is then carried to the high beam headlamps through circuit 12 (LG/BK). Circuit 1205 (BK) is the ground circuit for the headlamps and relay.
Possible Causes
- circuit 12 (LG/BK) open
- circuit 212 (DB) open
- circuit 632 (GY/OG) open
- circuit 697 (BN) open
- circuit 1205 (BK) open
- high beam relay
- multifunction switch
