Wireless-linked Return Function does not Operate: Description

When a door is unlocked, the certification ECU (smart key ECU) sends a door unlock signal and key ID signal to the position control ECU and switch. When the position control ECU and switch receives the door unlock signal, it stores the key ID. When the driver door is opened, the memory call and memory command information of the stored key ID is sent to each driving position related control ECU. Each control ECU receives the memory commands and performs the memory call operation according to predetermined control timing values.
