Password Programming

If a transmitter is lost or damaged, the module/receiver must be reprogrammed to communicate with a new transmitter. The passwords recorded in the module/receiver should not be deleted when power is off in the module/receiver.

Each module/receiver should be able to record five passwords. The following method is used to record new passwords in the module/receiver.
1. Connect the scan tool to the data link connector (DLC).
2. Turn the ignition ON.
3. Send the programming mode message to the module/ receiver.
4. Press any button on the transmitter to generate a data code including a password which will be recorded by the module/receiver. The module/receiver sends a response message to the scan tool to indicate that the first password has been recorded.
5. Repeat the action of pressing any button on the transmitter until the module/receiver has responded that the second, third, fourth, and fifth passwords have been recorded.
6. Turn the ignition OFF.
7. Disconnect the scan tool.
The module/receiver will exit the programming mode and switch to the normal operating mode when either of the following conditions occurs:
- The scan tool is disconnected from the DLC.
- Five passwords have been recorded in the module/receiver.
