| Part | Description |
|---|---|
| BCM | Detects each switch condition by the combination switch reading function. Judges the illumination lamp ON/OFF status depending on the vehicle condition. And then it transmits position light request signal to IPDM E/R and combination meter via CAN communication, through the unified meter and A/C amp. |
| IPDM E/R | Controls the integrated relay according to the request from BCM via CAN communication. |
| Combination meter | Enters in the nighttime mode according to the request from BCM via CAN communication. Controls each illumination brightness in the nighttime mode. Refer to METER ILLUMINATION CONTROL: SYSTEM DIAGRAM . |
| Total illumination control unit | Turns each illumination (linked with hospitality lighting system) ON according to tail lamp signal from IPDM E/R Controls each illumination (linked with hospitality lighting system) brightness according to the illumination control signal from combination meter. |
| Combination switch (Lighting & turn signal switch) | Refer to SYSTEM DIAGRAM . |
COMPONENT DESCRIPTION
Description
BCM provides the step lamp power supply. Also BCM outputs it as the battery saver signal to total illumination control unit. And BCM cuts the power supply when the interior room lamp battery saver is activated.
BCM cuts the interior room lamp power supply depending on the vehicle condition. Total illumination control unit cuts the hospitality lighting power supply according to interior room lamp power supply (battery saver signal). This function prevents the battery from over-discharging if the driver neglects turning OFF any lamps.
Total illumination control unit provides the following lamps power supply according to the battery saver signal from BCM.
- Mood lamps (rear door armrest)
- Foot lamps
- Map lamps
- Center console indirect illumination (Ambience lamp)
- Personal lamps
- Vanity mirror lamps
- Push-button ignition switch illumination
Total illumination control unit provides the following lamps power supply according to the battery saver signal from BCM.
- Puddle lamp
- Mood lamp (front door armrest)
Total illumination control unit provides the following illuminations power supply according to the battery saver signal from BCM.
Illuminations
- Trip computer switch
- Illumination control switch
- Multifunction switch
- Climate controlled seat switch
- LDW switch
- Snow mode switch
- Door mirror remote control switch
- AFS OFF switch
- Headlamp aiming switch
- Mode select switch
- Clock
- Steering switch
- IBA OFF switch
- DCA switch
- VDC OFF switch
Controls the lamp (ground side) by PWM signal (duty) when the map lamp main switch is DOOR.

Controls the lamp (ground side) by PWM signal (duty).
Controls the lamp (ground side) by PWM signal (duty).
Controls the step lamp (ground side) to turn the step lamp ON and OFF.
Total illumination control unit inputs tail lamp signal from IPDM E/R.
HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal lamp operating.
Note. The blinking speed is normal while activating the hazard warning lamp.
