Smart Key Luggage Lock-In Prevention Function Does Not Operate

SMART KEY LUGGAGE COMPARTMENT LOCK-IN PREVENTION FUNCTION DOES NOT OPERATE

CIRCUIT DESCRIPTION
With the smart key inside the luggage compartment, press the back door opener switch. The smart 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 smart key receives the request and transmits its ID code to the antenna. The ID code is then sent to the smart ECU through the back door inner oscillator in order to be confirmed by the smart ECU. If the ID code is verified, the smart ECU sends a back door open signal to the instrument panel J/B assy (multiplex network body ECU) using the multiplex communication line an stops outputting request signals. The back door then can be opened.
