Scuff Plate Light Circuit

Scuff Plate Light Circuit

DESCRIPTION
The operation timing of the scuff plate lights is the same as that of the front and rear interior lights.

The scuff plate lights turn on when a door is opened, and turn off when the door is closed. This illumination setting can be canceled using the overhead J/B switch.

In addition, the scuff plate lights blink while the theft deterrent system is sounding an alarm.

The turning on and off of the scuff plate lights is controlled by the main body ECU LH based on various signals received through BEAN communication.

The main body ECU LH includes a MOS-FET (Metal Oxide Semiconductor - Field Effect Transistor) circuit that fades the scuff plate lights in and out by duty control.

This MOS-FET circuit has an overheat protection function as a fail-safe. If the main body ECU LH becomes excessively hot, the scuff plate lights turn off and remain off.

Normal operation will resume when the conditions required to turn on the scuff plate lights are met again.
