RECLINING SENSOR

Description

INFOID:0000000007356181

• The reclining motor is installed to the seat frame assembly.

• The pulse signal is inputted to the driver seat control unit when the reclining is operated.

• The driver seat control unit counts the pulse and calculates the reclining amount of the seat.
