Normal Operation - Low Beams
When the headlamp switch is placed in the HEADLAMPS ON position, voltage is routed to the multifunction switch through circuit 15S-LE14 (GN/RD). The voltage passes through the multifunction switch to the low beam relay coil through circuit 15S-LE19 (GN/BU). When the low beam relay is energized, voltage is routed through circuits 15S-DC16 (GN/BU) and 15S-DC17 (GN/BU) to the battery junction box (BJB) fuse 16 (10A) and fuse 17 (10A), respectively. The voltage is then routed through circuits 15S-LE16 (GN/OG) and 15S-LE23 (GN/WH) to the LH and RH headlamps, respectively.

Normal Operation - High Beams
When the multifunction switch is placed in the HIGH BEAM position, voltage is routed to the high beam relay coil through circuit 15S-LE12 (GN/YE). When the high beam relay is energized, voltage is routed to the battery junction box (BJB) through circuit 15S-DC27 (GN/BU). The BJB then routes the voltage through circuits 15S-LE22 (GN/OG) and 15S-LE15 (GN/BK) to the LH and RH headlamps, respectively.

- Circuit 15S-DC16 (GN/BU) short to voltage
- Circuit 15S-DC17 (GN/BU) short to voltage
- Circuit 15S-DC27 (GN/BU) short to voltage
- Circuit 15S-LE12 (GN/YE) short to voltage
- Circuit 15S-LE14 (GN/RD) short to voltage
- Circuit 15S-LE15 (GN/BK) short to voltage
- Circuit 15S-LE16 (GN/OG) short to voltage
- Circuit 15S-LE19 (GN/BU) short to voltage
- Circuit 15S-LE22 (GN/OG) short to voltage
- Circuit 15S-LE23 (GN/WH) short to voltage
- Low beam relay
- High beam relay
- Headlamp switch
- Multifunction switch
