Heating Control

• The seat cushion heater is integrated with a heat sensor that detects seat temperature. The heat sensor transmits the seat temperature as the heat sensor signal to the CPU integrated with the seat cushion heater.

• The CPU recognizes the seat temperature from heat sensor signal. It adjusts the seat temperature by stopping operation when the seat temperature reaches the operation stop temperature , and starting operation when the seat temperature reaches the operation start temperature .

  

Fail-safe

• Seat heater equips fail-safe function.

• When a malfunction occurs in the systems shown below, seat heater performs fail-safe control:

OUTLINE

The second row seat power walk in system is controlled by the second row seat power walk in control unit, and allows the second row seat to be pitched forward with a child seat installed for easy third row seat entry.

Signal transmission function list

DESCRIPTION

• The second row seat power walk in system is controlled by the second row seat power walk in control unit.

• The second row seat power walk in system is activated by the walk in side switch and walk in back switch.

• The operation status of the second row seat power walk in system can be checked by checking the indicators of the walk in side switch and walk in back switch.

OPERATION DESCRIPTION

• When the walk in side switch or walk in back switch are operated the second row seat power walk in control unit recognizes switch operation.

• When the second row seat power walk in control unit receives the walk in side switch or walk in back switch signal the seat angle sensor signals are monitored by the second row seat power walk in control unit.

• When the second row seat back is folded flat the seat angle sensor is activated.

• If the second row seat power walk in control unit receives a seat angle sensor signal indicating the second row seat back is folded flat second row seat power walk in operation is inhibited.

• When second row seat power walk in system operation is inhibited seat walk in motor operation isn’t permitted and the second row seat power walk in control unit blinks the walk in side switch and seat walk in back switch indicators.

• If the second row seat power walk in control unit receives a seat angle sensor signal indicating the second row seat back is upright second row seat power walk in operation is permitted and the second row seat power walk in control unit activates the seat walk in motor.
