How to Reset the Power Door Battery on a Toyota Siennaby Tara Kimball
If the power doors on your Toyota Sienna stick or stop responding, you may need to recalibrate the doors by resetting the power door system. You can reset the power door system at home to save the time spent at a dealership service center. Resetting the system will reprogram the battery and computer chip so that the doors respond to the door controls.
Press the sliding door control button on the Sienna's dashboard so that the red line on the button is illuminated. Close the sliding doors.
Raise the hood of the van, and disconnect the negative ("-") battery cable with a wrench. Wait 3 to 5 minutes, then reconnect the cable.
Press the "Open" button on the remote key fob to open the sliding doors. Close the door. Wait 10 seconds, then open the door with the remote again.
Close the door, and wait 10 seconds. Open the door with the remote a third time. Once the third cycle completes, the power door battery is reset.
