OMRON "A" Transmitter Programming: - HOW TO REGISTER THE SECRET CODE:

Each transmitter has its own stored secret code. When replacing the transmitter, receiver, or when an RKE problem is diagnosed as a secret code registration fault, the secret code must be registered in the receiver EEPROM. Since only two different codes can be stored in the EEPROM memory, when the registration procedure below is repeated twice, the old previously-registered code will be cleared. Registration of the secret code should only be done after confirming with the key that the door lock function operates correctly.

1. Check that all doors lock and unlock properly when using the key.

2. CAUTION
Always turn the ignition switch to "OFF" before connecting the scan tool
Connect the scan tool (MUT-II) to the data link connector (or ground pin No. 1 of the data link connector if a scan tool is not available).





3. Within 10 seconds after connecting the scan tool (or grounding pin No. 1 of the data link connector), turn the ignition switch to the ON or ACC position and then back to OFF a total of three times. During each cycle of the switch, make sure the switch remains ON for at least 1 second.

NOTE:
The doors will lock and unlock once at this time indicating that the system is in the registration mode.

4. Press either the LOCK or UNLOCK button on the transmitter to be registered three times within 10 seconds. The code is now registered.

5. After registration is completed, the door will lock and unlock once.

6. If there are two transmitters, register the first, then register the second using the same procedure within one minute. After completing the second registration, the doors will lock and unlock once.

NOTE:
The registration mode will terminate under any of the following conditions:

^ When registration of the two transmitter secret codes is complete.

^ When 1 minute has passed after registration mode is started.

^ If the scan tool (MUT-II) is disconnected (ground is released - ground removed from data link connector pin No. 1).

^ If the ignition switch is turned ON.

^ If any door is opened.

7. Disconnect the MUT-II (or remove the ground from the data link connector pin No. 1) and remove the ignition key.

8. Verify that both transmitters operate properly.
