INITIALIZATION RELATED TO POWER BACK DOOR

1. RESET BACK DOOR CLOSE POSITION

   Note

   Perform initialization of the power back door system (power back door ECU initialization) if one of the following is performed: 1) The cable is disconnected from the negative (-) battery terminal; 2) a wire harness, the power back door unit or back door lock is replaced or removed/installed; or 3) the ECU-B2 fuse is replaced or removed/installed. If initialization is not performed, the power back door system will not operate.

   
   

   1. When the back door is open and the cable is disconnected and reconnected to the negative (-) battery terminal, fully close the back door by hand.

      Tech Tips

      Initialization is not necessary if the cable is disconnected and reconnected to the negative (-) battery terminal while the back door is closed. However, because the power back door ECU recognizes that the back door is locked, the power back door system will not operate if the back door is not unlocked.

2. CHECK POWER BACK DOOR FUNCTION

   Tech Tips

   
   

   • Proceed to Operation Check.

   • If the power back door system does not operate and/or the back door does not open, disconnect the cable from the negative (-) battery terminal. Then wait 10 seconds, reconnect the cable and perform initialization of the power back door system again.
