SEAT: REAR POWER SEAT CONTROL SYSTEM: Folding Motor Circuit
- Folding Motor Circuit

DESCRIPTION

The fold seat control ECU receives a switch operation signal from the fold seat switch and activates the folding motor. At this time, the Hall IC (seat cushion position sensor) detects the actuation signal. The fold seat control ECU uses signals from the Hall IC (seat cushion position sensor) to detect if an object is caught or if any other abnormal condition has occurred.
