Circuit Description

WARNING: This page is about a different car, the 2003 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.

Receiving the door courtesy signal from the door ECU, the luggage room J/B ECU makes the rear seat buckle illumination on the opened door side come on.

Then, after the rear door is closed, it maintains the illumination ON for 15+/-3 sec. (the Illuminated entry system)

When all the doors are locked during this timer operation, it immediately lights off.
