PINPOINT TEST L: THE TURN SIGNAL LAMPS ARE INOPERATIVE

L1-L2:

L2-L4:

Normal Operation
The smart junction box (SJB) sends voltage reference signals to the multifunction switch through circuit 1393 (LB/RD) (LH turn signal) and circuit 1392 (LG/OG) (RH turn signal). When the multifunction switch is placed in the LH or RH TURN position, the signal is routed to ground.

Possible Causes
- Circuit 1392 (LG/OG) open
- Circuit 1393 (LB/RD) open
- Multifunction switch
- SJB
