When an owner key was newly registered, the registration completed message will be displayed on the multi-information display in the combination meter assembly for a period of 10 days after the new registration.
If the registration completed message is displayed even after 10 days have passed, there may be a malfunction in the certification ECU (smart key ECU assembly).
Before performing troubleshooting of the vehicle, refer to Precautions for Inspection or Registration to check for a cause of the malfunction which is not related to vehicle settings or vehicle components.
Perform troubleshooting with the electrical key transmitter sub-assembly not inside the detection area of the smart entry and start system.
Make sure that no DTCs are output. If any DTCs are output, proceed to Diagnostic Trouble Code Chart.
If the digital key system has been disabled, enable the system before performing troubleshooting.
Before replacing the certification ECU (smart key ECU assembly), refer to Service Bulletin.
Check the registration date of the owner key.
Refer to operation history of the digital key application
