A situation may arise when, in order to start the engine of the machine, it is necessary to turn off the immobilizer. Some motorists may have certain problems with this. In this case, you should know how to disable the immobilizer. Sometimes this is simply necessary, since there is no way, for example, to program keys directly in this device. Nevertheless, it is worthwhile to understand that after disabling the immobilizer, your car will become more accessible to all kinds of hijackers. That is why it must be equipped with a very good burglar alarm. It is advisable if she will have feedback. In order to understand the principle of operation of this device, sometimes it is necessary to read more than one article.
So how to get around the immobilizer? Almost always, it is turned off by acting on the engine control unit (immobilizer ECU). In most cases, there can only be one answer to the question of how to disable the immobilizer - cut the wire from the device that goes to the engine ECU. This shutdown mainly introduces into the
volatile memory of the engine control unit some changes that are responsible for the operation of the immobilizer with the unit. Such changes cannot affect the functionality of the vehicle as a whole, but only in the ECU firmware an immobilizer poll.
Sometimes, in order to avoid the question of how to disable the immobilizer, it is necessary to install a special electronic device in the engine control unit.
This can be either an emulator or a refinement of electrical circuits that already exist on a car. Almost always, such a device is made in the form of a board, which has a microprocessor and other electronic components. However, a situation may arise when it is simply impossible to disable this device on some cars, as it may affect the correct operation of not only the engine itself, but also other ECU systems. In this situation, only immobilizer repair or replacement and subsequent reprogramming of keys to synchronize them with the computer can help.
All manufacturers are unambiguously answering the question of how to disable the immobilizer - they do not recommend doing this at all. Many motorists will probably agree with them. A more correct way out of this situation is precisely the programming of car keys. But in very many cases, for example, when the control unit can be compared in value with the third part of the price of the entire vehicle, the only reasonable solution can only be a trip.
In a number of problems arising with the immobilizer, this output is the most acceptable. This can be attributed to cars produced in the late to mid-90s. Here, very often certain problems with the immobilizer antenna may occur. This can be troubles with wiring, leading to a complete loss of computer synchronization or to the loss of keys by this device. In the event of a constant occurrence of such problems and due to the high cost and inability to replace all the computers, it is worth completely disconnecting the device. In any case, it is necessary to entrust this task to professionals. Only then can you be completely sure that this procedure will be performed efficiently and correctly.
