Key Luggage Compartment Lock-in Prevention Function does not Operate: Description
WARNING: This page is about a different car, the 2011 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
If the key luggage compartment lock-in prevention function does not operate, either of the following may be the cause: 1) communication between the indoor electrical key oscillator (luggage compartment) and electrical key transmitter cannot be performed; or 2) a malfunction in the certification ECU (smart key ECU assembly).
