Password Programming

If a transmitter is lost or damaged, the control module/receiver must be re-programmed to communicate with the new transmitter. The passwords recorded in the control module/receiver should not be deleted when the power is off in the control module/receiver.
Each control module/receiver should be able to record five passwords. The following method is used to record new passwords in the control module/receiver:
1. Connect the scan tool to the assembly line data link connector (DLC).
2. Turn the ignition ON.
3. Delete the current passwords.
4. Send the programming mode message to the control module/receiver.
5. Press any button of the transmitter to generate a data code, including a password which will be recorded by the control module/receiver. The control module/receiver will then send a response message to the scan tool to indicate that the first password has been recorded.
6. Press any button of the transmitter to generate a data code including a password which will be recorded by the control module/receiver. The control module/receiver will then send a response message to the scan tool to indicate that the second password has been recorded.
7. Turn the ignition OFF.
8. Disconnect the scan tool.

The control module/receiver automatically leaves the programming mode and switches to the normal operating mode when either of the following conditions occurs:
- The scan tool is disconnected from the DLC.
- Five passwords are recorded in the control module/receiver.
