DAYTIME RUNNING LIGHT SYSTEM

System Diagram

INFOID:0000000009478429

System Description

INFOID:0000000009478430

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

applied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate

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

brake is applied.

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:0000000009478433

System Description

INFOID:0000000009478434

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

When the combination switch (lighting and turn signal 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 

BCS-18, "HEADLAMP : CONSULT 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 combination switch (lighting and turn signal switch) is

in the AUTO position, the BCM automatically turns the lamps ON/OFF according to ambient light brightness.

When the key is turned OFF and all doors are closed, the auto light system keeps the headlamps ON for 45

seconds. 

NOTE:

Timing for when lamps turn ON/OFF can be changed by the CONSULT. Refer to 

BCS-18, "HEADLAMP :

CONSULT Function (BCM - HEADLAMP)"
