Test D: One Low Beam Headlamp Is Inoperative

PINPOINT TEST D: ONE LOW BEAM HEADLAMP IS INOPERATIVE

Normal Operation
When the headlamp switch is placed in the HEADLAMPS ON position, the smart junction box (SJB) routes voltage to the LH and RH low beams through circuits CBP04 (VT) and CBP03 (GY), respectively. Ground is provided to the LH and RH headlamps through circuits GD121 (BK/YE) and GD123 (BK/GY), respectively.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- SJB
