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.

When the front part of the slide switch of the power seat control switch is pushed up, the signal is input to connector P19 terminal No. 19 of the power seat ECU. This activates the power seat ECU to flow the current into connector P18 terminal No. 10 of the power seat ECU to terminal No. 1 of the power seat motor (front vertical control) to terminal No. 2 to connector P18 terminal No. 9 of the ECU to ground, to raise the front part of the seat cushion while the power seat control switch is kept pressed.

When the front part of the slide switch of the power seat control switch is pushed down, the signal is input to connector P19 terminal No. 7 of the power seat ECU. This activates the power seat ECU to flow the current into connector P18 terminal No. 9 of the power seat ECU, terminal No. 2 of the power seat motor (front vertical control) to terminal No. 1 to connector P18 terminal No. 10 of the ECU to ground, to lower the front part of the seat cushion while the power seat control switch is kept pressed.

At this time, the power seat position sensor (front vertical control) detects the seat cushion position (front) and always inputs the signal to connector P19 terminal No. 3 of the power seat ECU.
