- How the Circuit Works
Low Beam OperationRefer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
With the headlight switch in HEAD and the dimmer
switch in LO, current flows through the headlight
switch, fuse 21 , tuse 22, and the low beam
filaments to ground, and the low beams come on.
tligh Beam Operation
With the headlight switch in HEAD and the dimmer
switch in Hl, current flows through the headlight
switch, dimmer/passing switch, fuses 4, 5, 21, and
22, and the low and high beam filaments to ground,
and the low and high beams come on.
Current also tlows through the high beam indicator
light to ground. The high beam indicator comes on
to remind the driver that the high beams are on.
Flash operation
The flash feature works with the headlight switch in
OFF, PARK, or HEAD (low beams). When you
move the flash-to-pass switch to ON, current flows
through the switch, fuses 4 and 5, and the high
beam filaments to ground, and the high beams
flash. The high beam indicator also flashes during
the flash oDeration. The flash function has no effect
it the high beams are already on.
Daytime Running Lights Day Operation
When you turn the ignition to ON (ll) with the
parking brake released, the daytime running lights
control unit supplies battery voltage at the
WHT/RED wire. This voltage is applied to the high
beam headlights through the daytime running lights
resistor. Each high beam headlight receives less
than battery voltage causing them to come on al
reduced brightness.
lf the parking brake is set, a ground signal is applied
to the daytime running lights control unit at the
RED/GRN wire. It the parking brake is set when you
first turn the ignition switch to ON (ll), the high beam
headlights will remain off until you release the
parking brake. Once the high beam headlights are
in day mode, setting the parking brake will not
cause the headlights to turn off . When low or high
beam operation is requested, baftery voltage trom
the headlight switch is applied to the daytime
running light control unit via the RED/vVHT wire.
The daytime running light control unit then
discontinues the daytime running light mode.
