Scheme 1
Interior Room Lamp ON Operation
- BCM always turns the interior room lamp ON when any door opens.
- BCM activates the interior room timer in any of the following conditions to turn the interior room lamp ON for a period of time. Any door opened and all doors closed. Key switch is turned ON --> OFF. All door unlock signal is detected when all doors close with ignition switch OFF. Push switch is turned ON --> OFF.
Note. Restart the timer if new condition is input during the timer operating time.
Interior Room Lamp OFF Operation
BCM stops the timer in any of the following conditions to turns the interior room lamp OFF.
- The timer operating time is expired.
- Ignition switch position is ON with all doors close.
- All door lock operation is detected with all doors close (when locked with the door lock and unlock switch, ignition keyhole illumination to be turned OFF when the time up).
Component Description
| Part | Description |
|---|---|
| BCM | Activates the interior room lamp timer depending on the vehicle condition to turn the interior room lamps ON/OFF. |
| Remote keyless entry receiver | Receives the lock/unlock signal from Keyfob. Transmits the lock/unlock signal to BCM. |
| Intelligent Key unit | Transmits the lock/unlock signal and push switch signal to BCM with CAN communication. |
| Door lock and unlock switch Key cylinder door lock and unlock switch | Inputs the lock/unlock signal to BCM. |
| Door switch Back door switch | Inputs the door switch signal to BCM. |
| Key switch | Inputs the key switch signal to BCM. |
COMPONENT DESCRIPTION
Scheme 2
| Part | Description |
|---|---|
| BCM | Operates the interior room lamp battery saver depending on the vehicle condition to cut the interior room lamp power supply. |
| Remote keyless entry receiver | Receives the lock/unlock signal from Keyfob. Transmits the lock/unlock signal to BCM. |
| Intelligent Key unit | Transmits the lock/unlock signal and push switch signal to BCM with CAN communication. |
| Door lock and unlock switch Key cylinder door lock and unlock switch | Inputs the lock/unlock signal to BCM. |
| Door switch Back door switch | Inputs the door switch signal to BCM. |
| Key switch | Inputs the key switch signal to BCM. |
COMPONENT DESCRIPTION
Scheme 3
| Part | Description |
|---|---|
| BCM | Judges 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 (with CAN communication). |
| IPDM E/R | Controls the integrated relay according to the request signal from BCM (with CAN communication). |
| Combination meter | Enters in nighttime mode according to the request from BCM (with CAN communication). Controls each illumination in the nighttime mode. Refer to " METER ILLUMINATION CONTROL : SYSTEM DIAGRAM ". |
| Combination switch (Lighting & turn signal switch) | Refer to " SYSTEM DIAGRAM ". |
COMPONENT DESCRIPTION
Description
Provides the interior room lamp power supply. Also cuts the power supply when the interior room lamp battery saver activating.
Controls each interior room lamp (ground side) by PWM signal.
Note. PWM signal control period is approximately 250 Hz (in the gradual brightening/dimming).
Controls the ignition keyhole illumination (ground side) by PWM signal.
Note. PWM signal control period is approximately 250 Hz (in the gradual brightening/dimming).
Controls the luggage room lamp (ground side) to turn the luggage room lamp ON and OFF.
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.
