B2128 UART COMMUNICATION LINE
DescriptionINFOID:0000000001735458
Driver seat control unit performs UART communication with the automatic drive positioner control unit using 2
communication lines, TX and RX line. Driver seat cont rol 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.

2. Disconnect driver seat contro l unit and automatic drive posi-
tioner control unit.
3. Check continuity between driver seat control unit harness con- nector and automatic drive positioner control unit harness con-
nector.
4. Check continuity between driver seat control unit harness connector and ground.
