PINPOINT TEST E: THE HEADLAMPS ARE ON CONTINUOUSLY

Normal Operation
When the headlamp switch is placed in the HEADLAMPS ON position, the headlamp switch routes voltage to the multifunction switch through circuit 164 (VT/LB).

When the multifunction switch is in the LOW BEAM position, the multifunction switch routes the voltage to the smart junction box (SJB) through circuit 13 (RD/BK). The SJB then routes the voltage to the LH and RH low beams through circuits 1055 (WH/LG) and 1056 (DB/LG), respectively.

When the multifunction switch is in the HIGH BEAM position, the multifunction switch routes voltage to the SJB through circuit 632 (GY/OG). The SJB then routes voltage to the high beams through circuit 12 (LG/BK).

Possible Causes
- Circuit 12 (LG/BK) short to voltage
- Circuit 13 (RD/BK) short to voltage
- Circuit 164 (VT/LB) short to voltage
- Circuit 632 (GY/OG) short to voltage
- Circuit 1055 (WH/LG) short to voltage
- Circuit 1056 (DB/LG) short to voltage
- Headlamp switch
- Multifunction switch
- SJB
