    the registered ignition key code that is registered in the
    current ECU can not be rewritten.

• Prepare a new ECU [A] and 2 new ignition keys [B].
                              NOTE
  ○The key registration unit is not required.

  it to “ON.”

○If there is any problem in the registration, the red warning
  indicator light (LED) and immobilizer warning indicator [A]
