Driving Position Memory Function
WARNING: This page is about a different car, the 2002 Lexus GS 430 and 2002 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.
Each position sensor in the seat detects the number of rotations of the relevant motor (seat movement amount) and inputs it to the ECU. This makes it possible to store and recall the seat position by operating the position memory switch. The driving seat position is stored and recalled through communication control of the body ECU and door ECU etc.
