SLIDING SENSOR

SLIDING SENSOR

Description

INFOID:0000000003134725

• The sliding sensor is installed to the seat slide cushion frame.
• The pulse signal is inputted to the driver seat control unit when sliding is performed.
• The driver seat control unit counts the pulse and calculates the sliding amount of the seat.
