PINPOINT TEST D: ONE LOW BEAM HEADLAMP IS INOPERATIVE

Test D1:

Normal Operation
The headlamp switch sends power through circuit 13 (RD/BK) 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) open
- circuit 160 (DB/WH) (LH headlamp) open
- circuit 161 (DG/OG) (RH headlamp) open
- circuit 1205 (BK) open
