Remote Transmitter: Operation

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.

Wireless door lock control system provides 4 modes of programming.

  • ADD Mode -Β  This mode allows additional remote transmitters, maximum of 4, to be registered. Attempting to register more than 4 remote transmitter recognition codes will cause the first remote transmitter code registered to be erased.
  • REWRITE Mode -Β  This mode erases all previously registered remote transmitter codes and registers only new recognition codes.
  • PROHIBITION Mode -Β  This mode erases all registered remote transmitter codes and cancels wireless door lock control functions. Use this mode if a transmitter becomes lost.
  • CONFIRMATION Mode -Β  This mode is used to determine how many remote transmitter codes are currently registered.
