Power Tilt And Power Telescopic Steering Column System -- System Description |
| 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. |
| MANUAL OPERATION |
The tilt and telescopic positions can be adjusted as desired by operating the tilt and telescopic switch.
| AUTO AWAY/RETURN FUNCTION |
When the engine switch is turned off, the steering column moves forward, away from the driver, and also tilts up for easy ingress and egress.
When the engine switch is turned on (IG), the steering column returns to the previously set position.
The auto away/return function can be prohibited by using the intelligent tester.
| DRIVING POSITION MEMORY FUNCTION (with Seat Position Memory System) |
The system can memorize and recall two 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.
