WARNING: This page is about a different car, the 2002 Lexus GS 430 and 2002 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When replacing the door lock control receiver and transmitter, registration of the recognition code is necessary because they are provided as single components.
- Select which mode should be performed from the following modes:
- Add Mode - The add mode is used to retain codes already registered while you register new recognition codes. This mode is used when adding a transmitter. However, if the number of registered codes exceed 4 codes, previously registered codes are correspondingly erased in order, starting from the first registered code.
- Rewrite Mode - The rewrite mode is used to erase all previously registered codes and register only new recognition codes.
- Prohibition Mode - The prohibition mode is used to erase all registered codes and cancels the wireless door lock function. Use this mode when the transmitter is lost.
- Confirmation Mode - The confirmation mode is for confirming how many recognition codes are already registered before you register additional recognition codes.
NOTE:
When the procedure is out of the specified, the operation returns to normal operation. A maximum of 4 recognition codes can be registered.
