Power Door Lock Control System: Initialization

WARNING: This page is about a different car, the 2006 Lexus RX 400h. However, it is still accessible from the selected car via links, so may be relevant.

BACK DOOR LOCK
1. When the battery is reconnected: If the back door is locked and therefore cannot be opened, it is necessary to unlock the back door using the door control switch or transmitter switch.
2. 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, as well as to make the system disabled. When the lock is replaced, be sure to perform the following: first properly connect the lock, second clear the DTC from memory using the intelligent tester and finally recheck that no DTC is output.
