Registering Transmitter Keys with ETACs

Each individual secret code is registered inside the transmitter, and so it is necessary to register these codes with the EEPROM inside the receiver in the following cases.
•When the transmitter or ETACS-ECU is replaced
•If more transmitters are to be used
•If it appears that a problem is occurring because of faulty registration of a code.
A maximum of four different codes can be stored in the EEPROM memory (four different transmitters can be used). When the code for the first transmitter is registered, the previously registered codes for all transmitters are cleared. Therefore, if you are using four transmitters or are adding more transmitters, the codes for all transmitters must be registered at the same time.

HOW TO REGISTER SECRET CODE
1.Insert the ignition key into the key cylinder and check that the doors have been locked normally when the ignition key is turned.
2.Insert the ignition key into the key cylinder.
3a.Turn the ignition switch to the "LOCK" (OFF) position and then connect data link connector terminal 1 to ground.
3b.Connect the OBDII vehicle data link connector terminal 1 to ground (pin4 or pin5).
NOTE: Connecting terminal 1 of the data link connector to ground will put the system in secret code registration standby mode.
4.Push the hazard warning light switch six times within 10 seconds.
NOTE:
At this time the code registration monitor request is output and becomes registration mode (all doors locked and then all doors unlocked).
NOTE:
The hazard warning light switch is turned on and off alternately whenever it is pushed.
5.Press the transmitter button, and then press it two times within 10 seconds of the first press. This will register the code.
6.When registration is completed, the code registration monitor request is output (all doors locked and then all doors unlocked).
7.If you are using two or more transmitters or have added a second transmitter, the next transmitter should be registered within one minute after registering the code for the previous transmitter. The registration procedure is common for all the transmitter.
8.Registration mode will be canceled under the following conditions:
•When the secret code for four transmitters has been registered;
•When passing one minute after finishing the registration of all transmitters;
•When no secret codes have been registered for more than one minute after the registration mode is entered;
•When the data link connector terminal 1 to ground is disconnected;
•When the ignition key is removed from the ignition key cylinder;
9.After the registration is completed, carry out the following.
Turn the ignition switch to the "LOCK" (OFF) position and then disconnect data link connector terminal 1 from ground.
10.Disconnect data link connector terminal 1 from ground.
11.Remove the ignition key from ignition key cylinder.
12.Close all of the doors.
13.Verify the keyless entry system operates normally.
