LIFTING SENSOR (REAR)

LIFTING SENSOR (REAR)

Description

INFOID:0000000009176629

• The lifting sensor (rear) is installed to the seat frame.

• The pulse signal is input to the driver seat control unit when the lifting (rear) is operated.

• The driver seat control unit counts the pulse and calculates the lifting (rear) amount of the seat.

Component Function Check
