RESET BACK DOOR CLOSE POSITION
Note
Perform initialization of the power back door system back door close position (multiplex network door ECU initialization) in the following cases:
The cable is disconnected from the negative (-) battery terminal.
A wire harness of the power back door system is disconnected and reconnected.
The multiplex network door ECU is replaced or removed and reinstalled.
The SHORT PIN or MPX-B NO. 1 fuse is replaced or removed and reinstalled.
The power back door unit assembly set LH or RH is replaced or removed and reinstalled.
The back door lock assembly is replaced or removed and reinstalled.
If initialization is not performed, the power back door system will not operate.
If the back door is open when the cable is disconnected and reconnected to the negative (-) battery terminal, fully close the back door by hand to initialize the multiplex network door ECU.
Tech Tips
Initialization is not necessary if the cable is disconnected and reconnected to the negative (-) battery terminal while the back door is closed.
The multiplex network door ECU controls the locked or unlocked state of the back door based on its memory. If the power for the multiplex network door ECU is disconnected and reconnected, the back door will need to be unlocked before it can be operated.
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. Wait 10 seconds, reconnect the cable and perform initialization of the power back door system again.
RESET BACK DOOR OPEN POSITION
Note
Perform initialization of the power back door system back door open position (multiplex network door ECU initialization) in the following case:
The multiplex network door ECU is replaced.
If the back door opening position stored in the multiplex network door ECU is not the fully open position, record the stored opening position before replacing the multiplex network door ECU and perform the position memorization after replacement.
