Wireless-linked Return Function does not Operate [12/2019 - 11/2023]: Description

When a door is unlocked using the wireless unlock function, the certification ECU (smart key ECU assembly) sends a key ID signal to the main body ECU (multiplex network body ECU). When a door is unlocked using the entry unlock function, the certification ECU (smart key ECU assembly) sends a door unlock signal and key ID signal to the main body ECU (multiplex network body ECU). When the main body ECU (multiplex network body ECU) receives the door unlock signal, it stores the key ID. When the driver door is opened, the memory call information of the stored key ID is sent to each driving position related control ECU. Each control ECU receives the information and then performs the memory call operation according to predetermined control timing values.
