Seat Memory Switch

COMPONENT FUNCTION WITHIN SYSTEM

• Set switch: It is used for registration and setting change of driving position.

• Memory switch: The maximum 2 driving positions can be registered by memory switch 1 to 2.

• Memory indicator: Memory indicator indicates the status of automatic driving positioner system by turning ON or blinking.

INDIVIDUAL COMPONENT FUNCTION

• Detects set switch operation

  .

• Detects memory switch operation.

• Turns ON/blinks the indicator lamp.

• Set switch: When set switch pressed, transmits set switch signal to seat control unit.

• Memory switch: When memory switch 1 or 2 pressed, transmits memory switch 1 or 2 signal to seat control unit.

Tilt & Telescopic Switch

COMPONENT FUNCTION WITHIN SYSTEM

• The steering column can be adjusted by operating the tilt & telescopic switch.

  

• The tilt & telescopic switch inputs the operation status of the switch to the steering column control module.

INDIVIDUAL COMPONENT FUNCTION

Detects tilt & telescopic switch operation.

COMPONENT OPERATION

When each switch is pressed, the voltage from the steering column control module changes according to the resistance value set for each switch, and the steering column control module reads which switch is operated.

COMPONENT PARTS LOCATION

Tilt & telescopic switch is installed to the steering column cover lower. Refer to Component Parts Location.

Tilt & Telescopic Motor

COMPONENT FUNCTION WITHIN SYSTEM

Tilt & telescopic motor consists of a tilt motor and telescopic motor .

• Tilt motor: Operated by power supply from the steering column control module, it upwards and downwards the steering column.

• Tilt sensor: The sensor built into the tilt motor detects the tilt position of the steering column and inputs it to the steering column control module.

• Telescopic motor: Operated by power supply from the steering column control module, it forwards and backwards the steering column.

• Telescopic sensor: The sensor built into the telescopic motor detects the telescopic position of the steering column and inputs it to the steering column control module.

INDIVIDUAL COMPONENT FUNCTION

• Move the steering column upward and down ward.

• Move the steering column forward and backward.

COMPONENT OPERATION

• Tilt motor: The steering column is moved upward and downward by changing the direction of rotation according to the input signal from the steering column control module.

• Tilt sensor: When the tilt motor is activated, a pulse signal is input from the tilt sensor to the steering column control module, and the steering column control module counts the pulse to calculate the tilt position of the steering column.

• Telescopic motor: The steering column is moved forward and backward by changing the direction of rotation according to the input signal from the steering column control module.

• Telescopic sensor: When the telescopic motor is activated, a pulse signal is input from the telescopic sensor to the steering column control module, and the steering column control module counts the pulse to calculate the telescopic position of the steering column.

COMPONENT PARTS LOCATION

Tilt & telescopic motor is installed to the steering column assembly. Refer to Component Parts Location.
