Toyota Sienna Service Manual: Initialization

Toyota Sienna Service Manual / Engine hood / door / Back door closer system / Initialization

1. RESET

When the battery is reconnected: The back door is locked and therefore cannot be opened. Therefore, it is necessary to unlock the back door using the door control switch or transmitter switch.
Reset the power back door system: The power back door ECU records the fully open position and the fully closed position of the power back door in its memory and the power back door fully opens and closes based on this memory. The power back door cannot operate without this memory. In the case where the battery has been removed, manually close the back door fully to reset the power back door system. However, if the battery is removed / installed when the back door is fully open, the power back door operates normally, thus the resetting the system is unnecessary
