Normal Operation
When the ignition switch is in the RUN position, voltage is sent by the smart junction box (SJB) to the multifunction switch through circuit 1039 (BK/YE). Voltage is then routed to the electronic flasher through circuit 383 (RD/WH) and then back to the multifunction switch through circuit 44 (LB).

Possible Causes
- Fuse
- Circuit 44 (LB) open or short to ground
- Circuit 383 (RD/WH) open
- Circuit 1039 (BK/YE) open
- Electronic flasher relay
- Multifunction switch
- SJB
