WARNING: This page is about a different car, the 2002 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

Four different programming modes are provided for the engine immobilizer system.

Registration Of Additional Sub-Key

This mode allows up to three more sub-key key identification codes to be registered with ECM.

This mode erases transponder key codes from ECM memory.
