Normal Operation
The cornering lamps are provided voltage when the parking lamps are on through circuit 14 (BN). The ground path is routed to the multifunction switch through circuits 380 (VT/YE) and 379 (BN/WH) for the LH and RH cornering lamps, respectively. When the multifunction switch is placed in the LH or RH TURN position, the multifunction switch completes the ground path through circuit 57 (BK).

Possible Causes
- Circuit 14 (BN) open
- Circuit 379 (BN/WH) open
- Circuit 380 (VT/YE) open
- Multifunction switch
