Function

Multiplex tilt and telescopic
ECU

This ECU sends a control signal to the power tilt motor and power
telescopic motor, based on signals from each switch, to adjust the
steering position.

Power tilt motor (built-in tilt
position sensor)

This motor is activated by a signal from the multiplex tilt and
telescopic ECU and adjusts tilt position.
Tilt position sensor in the motor detects the tilt position by counting the
number of pulses as the motor rotates.

Power telescopic motor (built-in
telescopic position sensor)

This motor is activated by a signal from the multiplex tilt and
telescopic ECU and adjusts the telescopic position.
Telescopic position sensor in the motor detects the telescopic position
by counting the number of pulses as the motor rotates.
