LIFTING SENSOR (REAR)

LIFTING SENSOR (REAR)

Description

INFOID:0000000003759170

• The lifting sensor (rear) is installed to the seat cushion frame. 
• The pulse signal is inputted 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.
