Circuit Description

WARNING: This page is about a different car, the 2004 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.

The rear seat control switch assembly operates rear seat adjustments like sliding forward/rearward and headrest upward/downward.

It is built into the rear armrest assembly. A light built into the switch assembly illuminates when the armrest is opened and turns off when the armrest is closed.

The switch assembly uses the multiplex communication circuit to transmit signals to the rear power seat LH and RH ECU.
