Headlight
Description
The low beam lights are projector-type lights which are more compact while maintaining sufticient brightness. Bundlingthe light rays reduces stray light and yields a spotlight-effect which improves visibility during night or foul weather driving.For easier aiming, the headlights are equipped with vertical and horizontal gauges.
NOTE: As the outer lenses are made of a resin material, don't cover the headlights when they a.e turned on.

Headlight Replacement
1. Remove the front bumper (see section 20).
2. Remove the mounting bolts, then pull out the head-
light, and disconnect the connectors from it.
After replacement, the horizontal and venical aim-
ing must be checked using conventional methods.
Use the aiming charts on page 23-171.
Bulb Replacement
CAUTION:
a Halogen headlights can becomo very hot in use; do
not touch them or the attaching haldware imm6diately
after they have been tuh6d ott.a Do not try to replace or cl6an the headlights with tho
lights on.
1. Disconnect the 2P connector(s) from the headlight.
Turn the bulb(s) counterclockwise and remove the
bulb(s).

- How the Circuit Works
With the ignition switch in ON (ll) or START (lll),
voltage is applied to the A,/T gear position indicator.
The A,/T gear position switch provides a ground for
each position. As an input is grounded, ils indicator
light comes on. lf you se,ecl B, tor example, ground
will be applied to the input of the A,/T gear position
indicator, and the R indicator bulb will come on.
With the headlight switch in PARK or HEAD, voltage
is applied to the RED/BLK wire terminal. this
changes the indicator panel illumination from lixed
to controlled by the dash lights dimmer inpul
through the RED wire.
When the lransmission ('98.99 models) or
powertrain ('00 model) control module (TCM or
PCM) detects an abnormality in the automatic
transmission control system, or when you request
diagnostic trouble codes through the service
check connector, the TCM or PCM will make lhe D4
indicator light blink.
Refer to the Service Manual (Section 14,
Automatic Transmission) for soecific tests or
troubleshooting procedures.
