Key Luggage Compartment Lock-in Prevention Function does not Operate: Description

With the key inside the luggage compartment, press the back door opener switch. The certification ECU uses the back door oscillators (outer and inner) to output a request signal. The back door outer oscillator cannot verify an ID code in this situation. The key receives the request and transmits its ID code to the antenna. The ID code is then sent to the certification ECU through the back door inner oscillator in order to be confirmed by the certification ECU. If the ID code is verified, the certification ECU sends a back door open signal to the driver side junction block (main body ECU) using the multiplex communication line and stops outputting request signals. The back door then can be opened.
