FRONT FOG LAMP

System Diagram

INFOID:0000000006247628

System Description

INFOID:0000000006247629

The front fog lamps are activated with the combination switch (lighting and turn signal 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 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.

System Description

PARKING, LICENSE PLATE AND TAIL LAMPS OPERATION

When the lighting switch is in 1ST position, BCM detects the LIGHTING SWITCH 1ST POSITION ON. The

BCM sends a parking light ON request via the CAN communication lines to the IPDM E/R. The IPDM E/R then

activates the tail lamp relay which sends power to the parking and instrument illumination circuits.

EXTERIOR LAMP BATTERY SAVER CONTROL

With the combination switch (lighting and turn signal switch) in the 2ND position and the ignition switch is

turned from ON or ACC to OFF, the battery saver feature is activated.

Under this condition, the headlamps remain illuminated for 5 minutes unless the lighting switch position is

changed. If the lighting switch position is changed, then the headlamps are turned off.

This setting can be changed by CONSULT-III. Refer to

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

HEAD LAMP)"

OUTLINE

• BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the

status of each switch.

• BCM is a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a

maximum of 20 switch status.
