HEADLAMP DELAY
DESCRIPTION
The Headlamp Time Delay system is controlled by
the Body Control Module (BCM) through the head-
lamp relay.

OPERATION

The headlamp time delay system is activated by
turning the headlamps ON (high or low beam) while
the engine is running, turning the ignition switch
OFF, and then turning the headlamp switch OFF
within 45 seconds. The system will not activate if
more than 45 seconds elapse between ignition switch
OFF and headlamp switch OFF. The BCM will allow
the headlamps to remain ON for 90 seconds before
they automatically turn off. Refer to the Owner's
Manual for more information.
HEADLAMP LEVELING MOTOR

DESCRIPTION
HEADLAMP LEVELING SYSTEM
The Remote Headlamp Leveling System allows the
driver to adjust the headlamp beam pattern from the
interior of the vehicle to compensate for passenger or
cargo load. Only the vertical axis of the headlamp
beam can be adjusted.
A headlamp leveling switch is located on the
instrument panel and controls the headlamp leveling
motors/modules found on the headlamp modules. The
Leveling switch has three settings 0-2, 0 being the
lowest, 2 being the highest headlight beam vertical
setting.
NOTE: When performing a headlamp beam pattern
alignment on a vehicle equipped with headlamp lev-

eling, be certain the headlamp leveling switch is in
the "0" position before starting. Failure to do so will
result in an incorrect headlamp alignment.
HEADLAMP LEVELING MOTOR
Vehicles equipped with the remote headlamp level-
ing system, utilize headlamp leveling motors. Two
leveling motors are used per vehicle, one for each
headlamp. These leveling motors are attached to the
rear of the headlamp modules. They can be described
as a small semi-square shaped module with a electri-
cal connector attached to one side. Due to vehicle
design these motors can only be serviced or accessed
by removing the headlamp from the vehicle.

OPERATION

HEADLAMP LEVELING SYSTEM
Moving the headlamp leveling switch control knob
will adjust the voltage (rheostat) sent to the head-
lamp leveling motors. This signals the headlamp lev-
eling motors to move and adjust the vertical
headlamp beam pattern accordingly. The headlamp
switch must be "ON" in order for the leveling system
to function. Refer to the appropriate wiring informa-
tion. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
details of wire harness routing and retention, connec-
tor pin-out information and location views for the
various wire harness connectors, splices and grounds.
HEADLAMP LEVELING MOTOR
The headlamp leveling motors move the headlamp
and beam pattern according to the signal received
from the headlamp leveling switch. With the vehicles
headlamps " ON " a signal voltage is sent from the
headlamp leveling switch and received at each of the
headlamp leveling motors. This signal voltage (typi-
cally 2 – 9 volts) tells the headlamp leveling motors
where to position the headlamps. The headlamp lev-
eling motors are attached to the headlamps with a
pushrod snapped into the rear of headlamp reflector
mechanism.
