Toyota Sienna Service Manual: Reclining Motor Circuit

DESCRIPTION

The fold seat control ECU receives a switch operation signal from the power rear no. 2 seat switch and the fold seat switch, and activates the reclining motor. At this time, the Hall IC (seatback position sensor) detects the actuation of the seatback and sends a seatback actuation signal to the fold seat control ECU.

The fold seat control ECU uses signals from the Hall IC (seatback position sensor) to detect if an object is caught or if any other abnormal condition has occurred.
