Test D: One High Beam Headlamp Is Inoperative

PINPOINT TEST D: ONE HIGH BEAM HEADLAMP IS INOPERATIVE

D1:

D1-D2:

Normal Operation
When the smart junction box (SJB) detects the headlamp switch in the HEADLAMPS ON position and the multifunction switch in the HIGH BEAM position, the SJB sends voltage through circuit CLS08 (VT/GN) to the high beam headlamps. Ground is supplied on circuit GD121 (BK/YE) and circuit GD123 (BK/GY) for the LH and RH high beam headlamps, respectively.

Possible Causes
- Circuit CLS08 (VT/GN) open
- Circuit GD121 (BK/YE) open
- Circuit GD123 (BK/GY) open
- Headlamp assembly
