B2117 ADJ PEDAL MOTOR

Description

INFOID:0000000005256637

• The pedal adjusting sensor is installed to pedal adjusting motor assembly.

• The resistance of pedal adjusting sensor is changed according to the forward/backward position of pedal

assembly.

B2128 UART COMMUNICATION LINE

Description

INFOID:0000000005256646

Driver seat control unit performs UART communication with the automatic drive positioner control unit using 2

communication lines, TX and RX line. Driver seat control unit receives the operation signals of pedal adjusting

switch, door mirror remote control switch, set switch and memory switch and the position signals of adjustable

pedal sensor and door mirror sensor from the automatic drive positioner control unit and transmits the opera-

tion request signal.
