INTERIOR ROOM LAMP CONTROL SYSTEM: Component Description
| Part name | Description |
|---|---|
| BCM | Provides power and ground and controls timer functions for the interior room lamp, map lamp (if equipped) and trunk room lamp. |
| Push-button ignition switch (with Intelligent Key) | Provides ignition switch status to the BCM. |
| Key switch (without Intelligent Key) | Provides key in ignition switch status to the BCM. |
| Door switches | Provides door OPEN/CLOSED status to the BCM. |
| Main power window and door lock/unlock switch | Provides door lock/unlock switch LH status to the BCM. |
| Power window and door lock/unlock switch RH | Provides door lock/unlock switch RH status to the BCM. |
| Front door lock key cylinder switch LH | Provides door lock/unlock switch LH status to the BCM. |
| Trunk lid lock assembly (with Intelligent Key) | Provides trunk lid OPEN/CLOSED status to the BCM. |
| Trunk lid switch (without Intelligent Key) |

ILLUMINATION CONTROL SYSTEM: Component Description
| Part name | Description |
|---|---|
| BCM | The BCM monitors the combination switch (lighting and turn signal switch) position. The BCM requests, via CAN communication, that the IPDM E/R activate the tail lamp relay. |
| IPDM E/R | The IPDM E/R activates the tail lamp relay based on inputs received from the BCM via the CAN communication network. |
| Combination meter (illumination control switch) | The illumination control switch is a part of the combination meter. The combination meter controls illumination intensity by varying resistance to the illumination lamps based on the illumination control switch position. |
| Combination switch (lighting and turn signal switch) | The combination switch (lighting and turn signal switch) provides input to the BCM about the combination switch (lighting and turn signal switch) position. |

ROOM LAMP TIMER OPERATION
When the interior room lamp switch is in the DOOR position and when all conditions below are met, the BCM begins timer control (maximum 30 seconds) for interior room lamp ON/OFF.
- When the front door LH is unlocked with key fob, main power window and door lock/unlock switch, power window and door lock/unlock switch RH or front door lock assembly LH (key cylinder switch).
- When a door opens --> closes and the push-button ignition switch is not pressed (with Intelligent Key).
- When a door opens --> closes and the key is not inserted in the ignition switch (without Intelligent Key).
Timer control is cancelled under the following conditions.
- When the front door LH is locked with key fob, main power window and door lock/unlock switch, power window and door lock/unlock switch RH or front door lock assembly LH (key cylinder switch).
- A door is opened (door switch turns ON).
- Ignition switch is turned ON.
Interior lamp operational settings can be changed with the function setting of CONSULT.
ILLUMINATION CONTROL SYSTEM: System Description
The illumination lamps operation is dependent upon the position of the combination switch (lighting and turn signal switch). When the combination switch (lighting and turn signal switch) is placed in the 1ST or 2ND position the BCM (body control module) receives input requesting the parking lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs power to the parking and illumination lamps, which then illuminate.
Description
Provides the battery saver output/power supply. Also cuts the power supply when the interior lamp battery saver is activated.
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 trunk room lamp (ground side) to turn the trunk room lamp ON and OFF.
Provides the power supply and the ground to control the push-button ignition switch illumination.
