Normal Operation
The multifunction switch receives voltage from the central junction box (CJB) fuse 7 (10A) through circuit 8 (OG/YE). The multifunction switch then routes the voltage to the electronic flasher through circuit 385 (WH/RD). The electronic flasher then sends voltage back to the multifunction switch through circuit 44 (LB).

When the multifunction switch is placed to the RH or LH turn position, the multifunction switch correspondingly routes the voltage to the LH or RH turn lamps.

Possible Causes
- Fuse
- Circuit 8 (OG/YE) open
- Circuit 44 (LB) open
- Circuit 385 (WH/RD) open
- Electronic flasher
- Multifunction switch
