B2128 UART COMMUNICATION LINE

B2128 UART COMMUNICATION LINE

Description

INFOID:0000000005515317

Driver seat control unit performs UART communication with the automatic drive positioner control unit using 1
communication lines. Driver seat control unit receives the operation signals of tilt & telescopic switch, door mir-
ror remote control switch, and the position signals of door mirror sensor from the automatic drive positioner
control unit and transmits the operation request signal.
