Circuit Description
WARNING: This page is about a different car, the 2005 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
- The power slide door ECU activates the slide motor to open/close the power slide door, thus controlling the power slide door operation. For jam and foreign object detection, the power slide door system uses the pulse sensor built into the slide motor and the touch sensor installed in the front side of the slide door.
- When the touch sensor comes in contact with an object while the slide door is closing, the resistance of the touch sensor changes which is monitored by the power slide door ECU. If a change in resistance is detected, the ECU will judge it to be a jam and foreign object detection in the direction that the power slide door is moving and reverse slide motor rotation. The touch sensor operates only while the slide door is closing. It does not operate while the slide door is opening.
- The pulse sensor detects changes in the operating speed of the slide door while the slide door is operating. When the sensor detects a change in the operating speed, the pulse from the sensor also changes, which is monitored by the power slide door ECU. If there is a pulse change detected, the ECU will judge it to be a jam and foreign object detection in the direction that the power slide door is moving and reverse slide motor rotation.
- If a jam and foreign object detection by the touch sensor and the pulse sensor has occurred 2 or more consecutive times and if the 2nd or most recent detection has occurred during closing, then the power slide door ECU will cancel automated slide door operation and switch the slide door to manual operation mode (not electrically controlled). In order to return the power slide door system to normal operation mode, perform either of the following: manually close the slide door fully or press the satellite switch for the power slide door or the power slide door control switch again (reset operation).
