Keyless Entry Transmitter: Testing and Inspection

HOW TO REGISTER A SECRET CODE
Each transmitter has its own stored secret code. When replacing the transmitter and receiver, or when it is concluded that the breakdown cause is 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 space, when the registration procedure is repeated twice, the old code can no longer be used. Registration of the code should be performed after confirming with the key that the door lock function is operative.

1. Connect the scan tool (MUT-II) to the data link connector.

NOTE: The No. 1 terminal of the data link connector is in the grounded state at this time, and the unit is ready for secret code registration.

CAUTION: Ensure that the ignition switch is in the OFF position when connecting and disconnecting the scan tool (MUT-II).

2. Close all doors.
3. Turn the ignition switch to the ACC position, then return to the OFF position.

NOTE: The door lock will lock and unlock to confirm that the registration mode is enabled.

4. Press the "Lock" or "Unlock" switch on the first transmitter to be registered once then press twice more within 10 sec and the code is registered.
5. After completing registration the door locks 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 door locks will lock and unlock once.

NOTE: The registration mode is cancelled under the following conditions.
- When registration of the two transmitter secret codes is complete.
- When 1 min has elapsed after setting registration mode.
- When the scan tool (MUT-II) is disconnected (ground released).
- When the ignition switch is turned ON.
- When any door is opened.

7. Disconnect the scan tool (MUT-II) and confirm that the transmitters) function(s) correctly.
