Circuit Description
WARNING: This page is about a different car, the 2003 Lexus ES 300 and 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
A switch signal via the luggage opening switch is transmitted from the body ECU inside the driver side junction box to the luggage compartment door lock, and the motor is driven by that. For circuit identification, see Fig 1.
