Test D: One Low Beam Headlamp Is Inoperative

PINPOINT TEST D: ONE LOW BEAM HEADLAMP IS INOPERATIVE

Test D1-D2:

Normal Operation
The multifunction switch routes power through circuit 13 (RD/BK) to CJB fuses 23 (10A) (RH headlamp) and 25 (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 57 (BK) is the ground circuit for the headlamps.

Possible Causes
- Circuit 13 (RD/BK) open
- Circuit 57 (BK) open
- Circuit 160 (DB/WH) (LH headlamp) open
- Circuit 161 (DG/OG) (RH headlamp) open
- CJB
