GENERAL INFORMATION
AUTOMATIC HEADLAMP SYSTEM
The Automatic Headlamp system turns the instru-
mentation and exterior illumination lamps ON when
the ambient light levels are low and OFF when light
levels are high. Automatic headlamps are controlled by
the Body Control Module (BCM). With the headlamp
switch in the AUTO position, the BCM will control the
headlamp, parking, side marker, tail and instrumenta-
tion lamps based on ambient light levels. Ambient
light levels are monitored by the BCM using the auto-
matic temperature control system Sun load Sensor,
located on the top of the instrument panel cover. Ambi-
ent light readings are averaged to limit cycling the
lamps ON and OFF when passing through areas with
varying light levels. The automatic headlamps will
only function when the engine is running. When the
headlamp switch is in the AUTO position (Automatic
mode), the Headlamp Time Delay system will function
when the ignition is switched OFF.
COURTESY LAMPS
The Body Control Module (BCM) illuminates the
courtesy lamps whenever a door is opened. When the
last door is closed, the BCM “fades-to-OFF” the cour-
tesy lamps in five seconds. If a door is left ajar, the
courtesy lamps remain on for a maximum of one
hour when ignition switch is OFF. After one hour, the
BCM “fades-to-OFF” the courtesy lamps.
DAYTIME RUNNING LAMPS – CANADA ONLY
The daytime running lamps are controlled by the
Daytime Running Lamp Module (DRL Module). The
DRL module is attach to the Junction Block. The
Junction Block is located on the left side of the
instrument panel. The DRL allows the high beam
headlamps to illuminate at reduced power when the
ignition switch is in the run position with the high
and low beam headlamp switches in the OFF posi-
tion. The Park Brake must be released and the
Brake Fluid Level switch must be in the open posi-
tion to allow the headlamps to operate in DRL mode.
The daytime running lamps will go out when the
headlamp switch is turned ON. The passing light fea-
ture will flash bright high beams while the daytime
running lamps are activated.
HEADLAMPS ON WITH WINDSHIELD WIPERS
Vehicles equipped with the Automatic Headlamp
System the instrumentation and exterior illumina-
tion lamps will be turned ON when the headlamp
switch is in the AUTO position and the windshield
wipers have been in the intermittent, low or high
mode of operation for more than ten seconds. When
the windshield wipers are turned OFF the Body Con-
trol Module will determine if the instrumentation
and exterior illumination lamps should remain ON
base upon the current ambient light level.
HEADLAMP SYSTEM
The headlamp system is controlled completely by
the Body Control Module (BCM). The BCM controls
the Park lamps, Headlamps, and Front Fog Lamps
using relays located in the Junction Block. Three
wires are connected between the headlamp switch
and the BCM. The first wire contains information
regarding the position of the headlamp switch (Off,
Automatic Headlamps, Automatic Headlamp switch
fog, Park with Fog, Head, or Head with Fog Lamps).
The second wire contains information regarding the
position of the dimmer switch (Dome Lamp, Daytime
Brightness, or Dimming Level). The third wire is a
dedicated signal return (ground) wire.
