Normal Operation
Under normal operation, when RH or LH turn is selected, the multifunction switch sends a ground signal to the smart junction box (SJB) through (LH) circuit 1393 (LB/RD) and (RH) circuit 1392 (LG/OG). The multifunction switch is grounded by the SJB through circuit 1396 (VT/WH).
Possible Causes
- An open in circuit 1396 (VT/WH), 1393 (LB/RD) or 1392 (LG/OG)
- Multifunction switch
- Smart junction box (SJB)
