HOW TO REGISTER SECRET CODE

Required Special Tools

1. MB991529: Diagnostic trouble code check harness
2. MB991958: Scan Tool (MUT-III Sub Assembly) MB991824: Vehicle Communication Interface (V.C.I.) MB991911: MUT-III Main Harness B 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.
3. When the transmitter or ETACS-ECU is replaced
4. If more transmitters are to be used
5. 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.

Scheme 99

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. CAUTION: Turn the ignition switch to the "LOCK" (OFF) position and then connect data link connector terminal 1 to ground.
3. Connect the data link connector terminal 1 to ground. 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 out- ) put and becomes registration mode (all doors locked and then all doors unlocked). 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 same registration procedure should be carried out within one minute after registering the code for the first transmitter. After the second registration is completed, the code registration monitor request is output (all doors locked and then all doors unlocked).
8. Registration mode will be canceled under the following conditions: When the secret code for four transmitters has been registered; When one minute has passed after registration mode started; 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. CAUTION: 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.
