POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM SYSTEM DESCRIPTION


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Multiplex tilt and telescopic ECU This ECU sends a control signal to the tilt motor and telescopic motor, based on signals from each switch, to adjust the steering position.
    Tilt motor (Built-in tilt position sensor)

    • This motor is activated by a signal from the multiplex tilt and telescopic ECU and adjusts the tilt position.

    • The tilt position sensor in the motor detects the tilt position by counting the number of pulses as the motor rotates.
    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.

    • The telescopic position sensor in the motor detects the telescopic position by counting the number of pulses as the motor rotates.

  2. MANUAL OPERATION


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

  3. AUTO AWAY/RETURN FUNCTION


    1. When the power source is changed from on (ACC) or on (IG) to off, and the multiplex tilt and telescopic ECU receives a seat belt release signal, the steering wheel automatically tilts up and fully retracts.

    2. When the power source is changed from off to on (ACC) or on (IG), or the multiplex tilt and telescopic ECU receives a seat belt fastened signal, the steering wheel automatically returns to the previous position which was set before the power source was turned off.

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

  4. DRIVING POSITION MEMORY FUNCTION (w/ Seat Memory)


    1. The system can memorize and recall three driving positions by operating the seat memory switch.

      Even if these positions are changed when the driver gets in or out of the vehicle, the system can restore the memorized position by the one-touch operation if the steering wheel column position and driver side seat position are stored.
