System Description

INFOID:0000000006247617

Control of the headlamp system operation is dependent upon the position of the combination switch (lighting

and turn signal switch). When the lighting switch is placed in the 2nd position, the BCM (body control module)

receives input requesting the headlamps and park lamps to illuminate. This input is communicated to the

IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU

(central processing unit) of the IPDM E/R controls the headlamp LH high, headlamp RH high and headlamp

low relay coils. When energized, these relays direct power to the respective headlamps, which then illuminate.

HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION

With the lighting switch in the 2ND position and placed in HIGH position, the BCM receives input requesting

the headlamp high beams to illuminate. The flash to pass feature can be used any time and also sends a sig-

nal to the BCM. This input is communicated to the IPDM E/R via the CAN communication lines. The CPU of

the combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R

controls the headlamp high relay coil which supplies power to the high beam headlamps.

The combination meter receives a high beam request signal (ON) via the CAN communication lines and turns

the high beam indicator lamp ON.

DAYTIME RUNNING LIGHT SYSTEM

System Diagram

INFOID:0000000006247620

System Description

INFOID:0000000006247621

The headlamp system for Canada vehicles is equipped with a daytime light control that activates the high

beam headlamps at approximately half illumination whenever the engine is operating. If the parking brake is

depressed before the engine is started the daytime lights will not be illuminated. The daytime lights will illumi-

nate once the parking brake is released. Thereafter, the daytime lights will continue to operate when the park-

ing brake is depressed.

OPERATION

The BCM monitors inputs from the parking brake switch and the combination switch (lighting and turn signal

switch) to determine when to activate the daytime light system. The BCM sends a daytime light request to the

IPDM E/R via the CAN communication lines. The IPDM E/R grounds the daytime light relay 1 which in turn,

provides power to the ground side of the LH high beam lamp. Power flows backward through the LH high

beam lamp to the IPDM E/R, through the high beam fuses, through the RH high beam lamp circuit to the RH

high beam lamp and on to ground. The high beam lamps are wired in series which causes them to illuminate

at a reduced intensity.

AUTO LIGHT SYSTEM

AUTO LIGHT SYSTEM

System Diagram

INFOID:0000000006247624

System Description

INFOID:0000000006247625

The auto light control system has an optical sensor that detects outside brightness.

When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking, license plate, tail and

headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details,

Refer to

EXL-29, "HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)"

.

AUTO LIGHT OPERATION

The auto light system operates the low beam and high beam headlamps, parking lamps, tail lamps and license

plate lamps. The BCM monitors the combination switch (lighting and turn signal switch) position as a part of

the BCM combination switch reading function. When the lighting switch is in the AUTO position, the BCM auto-

matically turns the lamps ON/OFF according to ambient light brightness.

NOTE:

Timing for when lamps turn ON/OFF can be changed by the function setting of CONSULT-III. Refer to

EXL-29,

"HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)"

.
