Normal Operation
The electronic flasher is supplied voltage from the central junction box (CJB) fuse 2 (20A) through circuit 383 (RD/WH). Ground to the electronic flasher is supplied through circuit 57 (BK). The electronic flasher routes the voltage to the multifunction switch through circuit 385 (WH/RD). When the hazard switch is placed in the ON position, the multifunction switch routes voltage to all of the turn lamps.

Possible Causes
- Fuse
- Circuit 383 (RD/WH) open
- Circuit 385 (WH/RD) open or short to ground
- Circuit 44 (LB) short to ground
- Circuit 57 (BK) open
