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.
The seat position will not be stored if the SET switch and 2 or more of the seat memory switches (for example, M1 switch and M2 switch) are pressed simultaneously.
If a memorizing operation has failed, release all of the switches. The seat memory function will not operate unless the switches are released.
Before replacing the main body ECU (multiplex network body ECU) or certification ECU (smart key ECU assembly), refer to Service Bulletin.
Check the operation of the power seat.
Check the seat position memory function.
Check the seat position restoration function.
Check the operation of memory registration of the memory call function.
