Test B: The Low Beams Are Inoperative
PINPOINT TEST B: THE LOW BEAMS ARE INOPERATIVEB1-B2:
B2-B3:
Normal Operation
When the headlamp switch is placed in the headlamps ON position, voltage is routed to the multifunction switch through circuit 15 (RD/YE). The multifunction switch then routes the voltage to the smart junction box (SJB) through circuit 13 (RD/BK). The SJB then routes the voltage to the low beam headlamps.
Possible Causes
- Circuit 13 (RD/BK) open
- Multifunction switch
- SJB
