The programming procedure. Hyundai Matrix (2002 and 2006 model year)

Programming key is performed after the replacement of a faulty engine control unit or the issuance of additional keys of the car owner.

The procedure begins with the fact that the engine control unit requests a screening device specific data of the vehicle. "Clean" the engine control unit records the data, then you can start programming the key. "Programmed" engine control unit compares the data from the screening device with the data stored in its memory. If the data match, the programming continues.

If the engine control unit receives three times the wrong vehicle specific data, it is less than 1 chotklonyaet request to programming key. The duration of this deviation can not be reduced by disconnecting the battery or other actions. After connecting the battery starts counting from zero.

Programming key is done by turning the ignition key and optional commands of the screening device. The engine control unit records the relevant data in the EEPROM in the memory of the transponder. After that, the engine control unit produces identification that is required for the approval of the programming process. Then perform the programming is confirmed by a message on the test device.

If the key is already known to the engine control unit on the basis of the previous key programming, produced his identification and update of data in the EEPROM. The contents of the memory of the transponder does not change (in the programmed transponder is not possible).

The engine control unit detects an attempt to re-program the key, already programmed for of the programming cycle. He rejects the request key and displays a message on the test device.

The engine control unit also rejects the current programming is key, issuing a message about it on the screening device. The key may not be applicable due to a malfunction of the transponder or for other reasons, caused by a bad data entry. The key is considered not applicable at mismatch identities transponder and the engine control unit.

If an error occurs when using the service menu immobilizer state of the engine control unit remains unchanged and in memory of a special fault code is entered.

If the programming of a state key ECU and a key do not match, the verification procedure is terminated, and the memory ECU recorded special DTC.

The user password used to start the engine in an emergency, is programmed at the service station. The user selects the four-digit password.

Programming the user password only "program" the engine control unit. Before the first user password, the engine control unit status of the password should be "clean." In this emergency the engine can not.

Programming is done by turning the ignition key, and the current issue of the user's password from the screening device. Upon successful programming, the user's password changes from a state of "pure" in the "Programmed" state.

Programmed user password can be changed. This is possible if the user's password is in the "program" and a screening device gives permission to access a user's password to continue or to specific data of the vehicle. After proper authorization engine control unit requests a new password. The new password remains in the "Programmed" state and will operate the next time an emergency engine start.

If the engine control unit is given an incorrect password three times by car or erroneous data, he spent hours rejects the request to change the password. The duration of this deviation can not be reduced by disconnecting the battery or other actions. After connecting the battery starts counting from zero.

This state is stored in the EEPROM. In the case of erroneous or incorrect information from the device engine control unit is unable to verify this condition and displays the message 00.

This state is entered at the end of the line of manufacturing the engine control unit before delivery of the car to the end user.

After a certain number of erroneous inputs ECU blocked for 1 hour, during which not received any input.

This state is set when, for example, the engine control unit is in the neutral condition.
