HINT:

  • ●: Operates without jam protection/catch protection
  • ▲: Inching operates for approximately 0.4 seconds without jam protection/catch protection
  • X: Operation prohibited

Fail-safe deactivation condition

  • When the pulse sensor is normal, to deactivate fail-safe mode, pull up the power window switch to the auto up position and hold it for at least 1 second to fully close the window from the fully open position. As a result, the auto up/down function will return.

2. DISPLACEMENT OF NON-DETECTION RANGE TO THE OPENING DIRECTION

(a) If the window position or learned value is abnormal, the following power window operations are prohibited.

  • When the pulse sensor is normal, to deactivate fail-safe mode, pull up the power window switch to the auto up position and hold it for at least 1 second to fully close the window from the fully open position. As a result, the auto up/down function will return.

3. INITIALIZATION FAILURE

(a) During initialization, when the window position or initialization complete status cannot be properly read from the non-volatile memory, the following power window operations are prohibited.

Fail-safe deactivation condition

  • Perform initialization (See page 2016 - 2020 MY Sienna [12/2015 -        ]; WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: INITIALIZATION ).

4. LIN COMMUNICATION FAILURE

(a) If the LIN communication line is malfunctioning (communication stop), the power window control system prohibits operation as follows. (Operation is only possible using the power window switch of each seat.)

5. PULSE FAILURE AND LIN COMMUNICATION FAILURE

(a) If the LIN communication line is malfunctioning (communication stop) and the pulse sensor is malfunctioning, the following power window operations are prohibited.

  • Switch on the door:

    When the jam protection function does not operate due to the LIN communication failure, the manual up and auto up functions will not operate, as the state of the IG signal is unknown.

  • Remote switch operation:

    Operation is not possible during the LIN communication failure.

6. DISPLACEMENT OF NON-DETECTION RANGE TO THE OPENING DIRECTION AND LIN COMMUNICATION FAILURE / INITIAL FAILURE AND LIN COMMUNICATION FAILURE

(a) If the LIN communication line is malfunctioning and the window position and learned value are abnormal, or the LIN communication line is malfunctioning and the window position or initialization complete status cannot be properly read from the non-volatile memory during initialization, the following power window operations are prohibited.
