Toyota Sienna Service Manual: Initialization

1. RESET

  1. When the back door lock is replaced: The power back door ECU cannot receive a switch signal from the lock. This may cause the power back door system to enter fail-safe mode and DTC B2215 to set, and also make the system disabled.

    When the lock is replaced, be sure to perform the following: first properly connect the lock, second clear the DTC using the intelligent tester and finally recheck that no DTC is output.

  2. 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 fully closed 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.

    Replacing drive unit will also cause the memory of the door positions to be last. Therefore, in such a case resetting the system is necessary.

    Reset the power back door system as follows:

  1. Fully close the power back door if opened.
  2. Check that the back door fully open and fully close.

HINT: The jam protection function is enabled through the above initialization procedure.
