FUNCTION OF MAIN COMPONENTS

Component
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.

MANUAL OPERATION
  1. The tilt and telescopic positions can be adjusted as desired by operating the tilt and telescopic manual switch.


AUTO AWAY/RETURN FUNCTION
  1. When the ignition switch is turned OFF, the steering column moves away from the driver, and also tilts up for easy ingress and egress.

  2. When the ignition switch is turned ON, the steering column returns to the previously set position.

  3. The auto away/return function can be prohibited by using the Techstream.


DRIVING POSITION MEMORY FUNCTION
  1. The steering column moves to the previously set position by pressing the seat memory switches.
