AUTO LIGHT SYSTEM

AUTO LIGHT SYSTEM

System Diagram

INFOID:0000000005259714

System Description

INFOID:0000000005259715

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-28, "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 lighting switch (combination switch) position as a part of the BCM combi-

nation switch reading function. When the lighting switch is in the AUTO position, the BCM automatically 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-28,

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

Description

BCM

BCM (Body Control Module) controls auto light operation accord-
ing to signals from optical sensor, lighting switch, door switches, 
and ignition switch.

IPDM E/R

IPDM E/R (Intelligent Power Distribution Module Engine Room) 
operates parking, license plate, tail and headlamps according to 
CAN communication signals from BCM.

Combination switch (lighting switch)

The lighting switch outputs lighting requests to the BCM.

AUTO LIGHT SYSTEM

Optical sensor

Optical sensor detects ambient brightness and converts light 
(lux) to voltage, then sends the optical sensor signal to BCM.

Door switches 

Provides door OPEN input to BCM for auto light timer.

FRONT FOG LAMP

System Diagram

INFOID:0000000005259718

System Description

INFOID:0000000005259719

The front fog lamps are activated with the lighting switch (combination switch). The lighting switch signal to the

BCM is monitored with the BCM combination switch reading function. When the fog lamps are turned ON with

the lighting switch, the BCM sends a front fog lamp request signal via CAN communication lines to the IPDM

E/R. The IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.

FRONT FOG LAMP OPERATION

When the lighting switch is in front fog lamp ON position and also in 1ST or 2ND position or AUTO position

(headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP1, 2 ON or the AUTO LIGHT ON. The

BCM sends a front fog lamp request ON signal via the CAN communication lines to the IPDM E/R. The IPDM

E/R then turns ON the front fog lamp relay sending power to the front fog lamps.

TURN SIGNAL AND HAZARD WARNING LAMPS

System Description

INFOID:0000000005259723

TURN SIGNAL OPERATION

When the turn signal switch is in LH or RH position with the ignition switch in ON position, the BCM detects the

TURN RH or TURN LH ON request. The BCM outputs the flasher signal to the respective turn signal lamp.

The BCM also sends a turn indicator signal ON request via the CAN communication lines to the combination

meter. The combination meter then activates the appropriate turn signal indicator and audible buzzer.

HAZARD LAMP OPERATION

When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the

flasher signal (right and left). The BCM sends a hazard indicator signal ON request via the CAN communica-

tion lines to the combination meter. The combination meter then activates the hazard indicator and audible

buzzer.

REMOTE KEYLESS ENTRY OPERATION

The remote keyless entry receiver transmits a hazard request signal to the BCM, then BCM controls hazard

lamps.
