How to correctly disable the immobilizer on Lada Kalina and do I need to do this? Car owners do not have similar questions from scratch and are most often caused by problems when installing a new alarm system or the loss of keys from the ignition switch …
On Lada cars - Kalina (and other vehicles of the VAZ family), the APS-6 immobilizer (https://kharkov-online.com/files/images/objava/38072/160123.jpg) in conjunction with the power control unit refers to standard security system. Its function is to receive a start code from a chip in the ignition key via wireless inductive communication. In case of successful confirmation of the code, the immobilizer gives permission to disable the engine start blocking to the control unit. However, the aforementioned actions are performed by the immobilizer only upon its preliminary activation, otherwise it does not participate in the process of starting the engine.
Checking whether the immobilizer is activated on Kalina is quite simple. If the interior light goes out smoothly after about twenty seconds when the doors are closed, the immobilizer is activated.
Do I need to turn off the immobilizer on the VAZ?
In general, the standard security system on Kalina is quite stable in operation, although somewhat primitive by modern standards. With the addition of the provided, but not installed wiggle sensor, it may well compete with the "signaling" of the middle price category. Problems usually arise when installing a new auto-start alarm, which, as a rule, cannot be "made friends" with the system installed at the factory. In such cases, in some car services, without bothering with a question, they simply attach a spare key to the tape to the wires near the ignition switch, which for the system is equivalent to the owner who is constantly present in the car. This approach is fraught with the fact that in the hands of the attacker who broke the glass is the car key with all the ensuing consequences …
How to bypass immo on Kalina correctly?
Some car services, when installing an alarm with auto start, "bypass" problems with the immobilizer by placing a spare ignition key near the steering column, which is unacceptable from a safety point of view.
Disabling the immobilizer is a rather complicated and time-consuming procedure that requires special software and skills in working with a soldering iron. First of all, it is necessary to disconnect and short-circuit the wires from pins 9 and 18 of the immobilizer connector, thereby breaking its connection with the control unit and retaining the ability to test through the diagnostic block. Access to the immobilizer is possible by removing the decorative heater grille in the middle of the dashboard (https://www.ladaonline.ru/upload/iblock/a50/picsx5cgalerys5cfutur_027.jpg). Further, the difficulties associated with the need to clear the memory of the control unit from traces of the presence of an activated immobilizer in the system begin. For example, for the Bosch M797 + controller popular at Avtovaz, a unified K-line adapter, a laptop or a PC with special software (https://www.chiptuner.ru/download/progs/eeprecu.zip) and a memory dump of a clean untrained ECU from the same source. In addition, at the time of programming, it is necessary to perform some commutation soldering in the control unit. Therefore, in the absence of the necessary skills or equipment, it is advisable to give the unit for a quite reasonable fee for flashing it to a specialized service.
