Shift Illumination Circuit: Description

The turning on and off of the shift illumination 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 shift illumination 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 shift illumination turns off and remains off.

Normal operation will resume when the conditions required to turn on the shift illumination are met again.
