Function
Description
(Key Code Utility)

Key Registration

This function allows the registration of additional key codes for transponder keys (Master/Sub Keys) using a Registered Master Key.

Key Code Erasure

This function allows the user to erase all the key codes for transponder keys except the Registered Master Key used during this function.

Auto Registration Closure

This function allows the user to close "Auto Registration Mode" when less than three keys have been registered.

NOTE:
When a new ECU is installed, it is in the "Auto Registration Mode" from the factory.

This allows Transponder Keys to automatically register as they are inserted into the Ignition Cylinder. After three Transponder Keys are registered, the ECU closes "Auto Registration Mode". See the Repair Manual for further details.
