Normal Operation
The headlamp switch sends power through circuit 13 (RD/BK)/15 (RD/YE) to BJB fuses 42 (10A) (RH headlamp) and 43 (10A) (LH headlamp). After passing through the fuses, voltage is then carried through circuits 161 (DG/OG) (RH headlamp) and 160 (DB/WH) (LH headlamp) to the low beam headlamps. Circuit 1205 (BK) is the ground circuit for the headlamps.

Possible Causes
- Circuit 13 (RD/BK)/15 (RD/YE) open
- Circuit 697 (BN) open
- Circuit 196 (DB/OG) open
- Circuit 1205 (BK) open
- Circuit 632 (GY/OG) open
- Circuit 12 (LG/BK) open
- Multifunction switch
- High beam relay
