AUTO LIGHT SYSTEM
System DiagramINFOID:0000000003894281
System DescriptionINFOID:0000000003894282
OUTLINE
 Auto light system is controlled by each function of BCM and IPDM E/R.
Control by BCM- Combination switch reading function
- Headlamp control function
- Auto light function
- Delay timer function
Control by IPDM E/R- Relay control function
 Auto light system has the auto light function and the delay timer function.
- Auto light function turns the exterior lamps* and each illumination ON/OFF automatically according to the
outside brightness.
- When auto light system turns the exterior lamps ON with the ignition switch OFF, delay timer function turns
the exterior lamps OFF depending on the vehicle condition with the auto light function after a certain period
of time.
*: Headlamp (LO/HI), parking lamp, tail lamp and front fog lamp (Headlamp HI and front fog lamp depend on
the combination switch condition.)
AUTO LIGHT FUNCTION
 BCM detects the combination switch condition with the combination switch reading function.
 BCM supplies voltage to optical sensor when the ignition switch is turned ON or ACC.
 Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
 BCM judges outside brightness from the optical sensor signal and judges ON/OFF condition of the exterior
lamp and each illumination according to the outside brightness.
 BCM transmits each request signal to IPDM E/R with CAN communication according to ON/OFF condition
by the auto light function.
NOTE:
ON/OFF timing differs based on the sensitivity from the setting. The setting can be set by CONSULT-III. Refer
to EXL-215, "
HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)".
DELAY TIMER FUNCTION
BCM turns the exterior lamp OFF depending on the vehicle condition with the auto light function when the igni-
tion switch is turned OFF.
 Turns the exterior lamp OFF 5 minutes after detecting that any door opens (Door switch ON).
 Turns the exterior lamp OFF a certain period of time* after closing all doors (Door switch ON→OFF).

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM
System DiagramINFOID:0000000003894289
System DescriptionINFOID:0000000003894290
OUTLINE
Turn signal lamp and the hazard warning lamp is controlled by combination switch reading function and the
flasher control function of BCM.
TURN SIGNAL LAMP OPERATION
 BCM detects the combination switch condition by the combination switch reading function.
 BCM supplies voltage to the right (left) turn signal lamp circuit when the ignition switch is turned ON and the
turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.
HAZARD WARNING LAMP OPERATION
BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the
hazard warning lamp.
TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION
 BCM transmits the turn indicator signal to the combination meter with CAN communication while the turn sig-
nal lamp and the hazard warning lamp are operating.
 Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal
indicator lamp according to the turn indicator signal.
HIGH FLASHER OPERATION (FAIL-SAFE)
 BCM detects the turn signal lamp circuit status by the terminal current value.
 BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn sig-
nal lamp operating.
NOTE:
The blinking speed is normal while operating the hazard warning lamp.

DIAGNOSIS SYSTEM (IPDM E/R)
Concept of auto active test
 IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
 The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
