HOW TO REGISTER SECRET CODE


Each individual secret code is registered inside the transmitter, and so it is necessary to resister 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.

WHEN THE SPECIAL TOOL V.C.I. (MB991824) IS USED
1.Check that the doors lock normally when the key is used.
2.Insert the ignition key.

3.
caution Before connecting or disconnecting the V.C.I., turn the ignition switch to the "LOCK" (OFF) position.
Connect the V.C.I. to the diagnosis connector.

4.Press the hazard warning lamp switch six times within 10 seconds.
note Once the process is completed six times, then it will operate with all doors lock and unlock operations once and then go to the save mode.
note The hazard warning lamp switch is turned on and off alternately whenever it is pushed.
5.Press the transmitter switch, and then press it two times within 10 seconds of the first press. This will register the code.
6. Once the program is saved, it will operate once with the all doors and tailgate lock and unlock operations.
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 cancelled under the following conditions:

  • When the secret code for four transmitters has been registered;
  • When passing one minute after finishing the registration of all transmitter;
  • When no secret codes have been registered for more then one minute after the registration mode is entered;
  • When the V.C.I. is disconnected from the diagnosis connector;
  • When the key is removed from the key cylinder;
9.After the registration is completed, remove the ignition key and close all the doors, and then check that the keyless entry system operates normally.

WHEN THE M.U.T.-III AND SWS MONITOR IS USED
1.Check that the doors lock normally when the ignition key is inserted into the door key cylinder and turned.
2.Insert the ignition key in the ignition switch.

3.
caution Before connecting or disconnecting the M.U.T.-III and SWS monitor, turn the ignition switch to the "LOCK" (OFF) position.
Connect the SWS monitor to the M.U.T.-III. Refer to GROUP 54C, How to Connect The SWS Monitor .
4.Connect the M.U.T.-III to the diagnosis connector.
5.Select "Interactive Diagnosis" from the main menu.
6.Select "System Select" from "Interactive Diagnosis".
7.Select "SWS" from "System Select".
8.Select "Others" from the "List of models."
9.Select "SWS Monitor" from "SWS".
10.If "New communication between doors" is selected from "SWS monitor", the display screen will be changed. Select "Keyless Entry" from that screen.
11.Select "Keyless ID Regist" from "Keyless Entry" items.
12.Press the YES key to clear encrypted codes for all the current registered transmitters.
13.Push the hazard warning lamp switch to clear all the encrypted codes completely.
14.Push the switch of the transmitter to be registered consecutively three times. If another transmitter is registered, push the switch of that transmitter again consecutively three times.
15.Return to the previous step.
16.Select "Recept Inspect" from "Keyless Entry" items.
17.Push the transmitter switch. If the transmitter can receive signal normally, the screen will show variation of the received signals and whether the transmitter switch has been registered or not.
note For the keyless entry system, the signal reception can be examined regardless of whether the transmitter is registered or not.
18.Return to the main menu and complete.
19.Remove the M.U.T.-III.
20.Disconnect the SWS monitor.
21.Check that the keyless entry system works normally.
