Circuit operation

Headlights (with airbag)

Battery voltage is applied to the light switch through "HEAD" fuse, R wire and HEADLIGHT relay. In the "HEAD"
position of the light switch and the "HL" position of the dimmer switch, The relay routes GND through the light
switch terminal B(W/L) of E-01 through headlight switch and B wire and is energized.Battery voltage also is
applied to the LO beam filaments of the right and left headlight through the light switch, "HEAD LOW" fuse and
R/L wire.The headlight LO beams illuminate.
With the dimmer switch in the "HU" position, Battery voltage also is applied to the beam indicator and the HI
bean filaments of the right and left headlight through the light switch, "HEAD (HI)" fuse and R wire. The
headlight HI beams and HI beam indicators illuminate. When the flash-to -pass switch is activated, battery
voltage is applied to the beam indicators and the HI beam filaments of the right and left headlight through the
"HEAD" fuse, R wire, flash-to-pass switch, R wire and "HEAD HI" fuse. The headlight HI beams and HI beam
indicators illuminate. The beam indicators illuminate when the dimmer switch is in "HIGH" position or the flash-
to-pass switch is activated.

Troubleshooting

Headlights (With airbag)

Preliminary check:
Check an open lamp filament before proceeding with diagnosis. If headlight bulb is damaged, check connection of the
bulband replace bulb. Also, check "HEAD(25A)", "HEAD LOW(15A)" and "HEAD HI(15A)" fuse and HEADLIGHT relay. If
open, check for short and overload, replace fuses or relay and check that all system electrical connectors mated correctly.
Low beam headlights do not operate.
