- A registration request was sent while in another mode.
- During registration a different registration request was sent.
DESCRIPTION
If an electrical key transmitter sub-assembly could not be newly registered, wave interference or a malfunction of the certification ECU (smart key ECU assembly), electrical key transmitter sub-assembly, ID code box (immobiliser code ECU), steering lock ECU (steering lock actuator assembly) or door control receiver assembly is suspected.
The registration to add another electrical key transmitter sub-assembly (without replacing any parts) is called "additional key ID registration".
If additional registration is not possible, refer to "Additional Key cannot be Registered".
