REGISTRATION

PROCEDURE

1. REPAIR INSTRUCTION

CAUTION:

As weak radio waves are emitted from the electrical key transmitter sub-assembly, if a pacemaker is being used, be sure to read the pacemaker instruction manual and the following.

  • People with implantable cardiac pacemakers, cardiac resynchronization therapy-pacemakers or implantable cardioverter defibrillators should keep away from the smart key system antennas. The radio waves may affect the operation of such devices. If necessary, the entry function can be disabled. Ask your dealer for details, such as the frequency of radio waves and timing of the emitted radio waves. Then, consult your doctor to see if you should disable the entry function.

  • User of any electrical medical device other than implantable cardiac pacemakers, cardiac resynchronization therapy-pacemakers or implantable cardioverter defibrillators should consult the manufacturer of the device for information about its operation under the influence of radio waves. Radio waves could have unexpected effects on the operation of such medical devices.
  • Ask your dealer for details for disabling the entry function.

NOTICE:

PRECAUTION WHEN REPLACING PARTS

  • Code registration is necessary when any of the following parts is replaced with a new one. After replacing a part, any part that has performed registration cannot be returned.
    • Certification ECU (smart key ECU assembly)
    • Steering lock ECU (steering lock actuator or upper bracket assembly)
    • Electrical key transmitter sub-assembly
    • Main body ECU (multiplex network body ECU)
    • DCM (telephone transceiver assembly)*
      • *: for Toyota Entune Remote Connect Compatible Type

PRECAUTION FOR REGISTRATION

  • Make sure that only 1 electrical key transmitter sub-assembly is in the cabin during registration procedures. If 2 or more electrical key transmitter sub-assemblies are in the cabin simultaneously, the electric waves will interfere with each other, preventing normal registration.
  • A maximum of 7 electrical key transmitter sub-assemblies can be registered (this includes any electrical key transmitter sub-assemblies registered when the vehicle was purchased).
  • If the battery is depleted during the electrical key transmitter sub-assembly registration procedure, there may be cases in which the electrical key transmitter sub-assembly cannot be registered again. Therefore, make sure to perform work with a sufficiently charged battery.
  • If any of the work times are exceeded, finish the procedure.
  • Do not disconnect the battery during the Registration.
  • Do not perform operations that create an electrical load such as operating the power windows.
  • If "Smart Key System" is canceled, registration cannot be performed.
