If No CAN Communication Is Available With BCM
IGNITION RELAY MALFUNCTION DETECTION FUNCTION
IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop position by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop five times.
Control part Fail-safe operation
Cooling fan Turns ON the cooling fan relay-2 and the cooling fan relay-3 when ignition switch is

The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-
safe control is activated while the front wiper is set in the INT mode and the front wiper
motor is operating.

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).

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.
