Control unit condition

1

Door switch/Ignition 
switch

—

Driver seat control unit receives the signals of [ignition switch signal] 
and [driver side door switch] from BCM via CAN communication.

2

—

Motors
(Sliding, tilt, tele-
scopic)

Driver side control unit operates the sliding motor when the operating 
conditions are satisfied and requests the operations of tilt motor and 
telescopic motor to automatic drive positioner control unit via UART 
communication. The automatic drive positioner control unit operates 
each motor.

Sensors
(Sliding, tilt, telescop-
ic)

—

Each sensor monitors the operating positions of seat and steering, 
and then stops the operation of each motor when each part reaches 
the recorded address.
