System иммобилизации the engine - the device, a functioning principle, diagnostics of malfunctions

The scheme of an arrangement of the basic components of an immobilizer

1 — the Aerial
2 — the Display lamp (light-emitting diode)

3 — the management Module
4 — Transponder


The general information

The display lamp built in an instrument guard, the module of management of an immobilizer, the engine management module concern number of components of system иммобилизации the engine (ECM), built in a key head транспондер and a part of assemblage of the cylinder of the lock of ignition the antenna module.


The antenna module at key introduction in the ignition lock accepts transferred транспондером an identification code and transfers it to the module of management of an immobilizer which compares it to the reference code registered in the memory. At discrepancy of codes поворачивание a key in position ST will lead to start of the engine which, however, will spontaneously decay after already some seconds.

Immobilizer activation occurs automatically at extraction of a key from the ignition lock, and also later an order of 60 seconds after поворачивания a key in position АСС or OFF. Inclusion of a display lamp testifies To successful activation of system in a flashing mode (with duration of gleams 0.2 with and pauses in 2.8).

At infringement of serviceability of functioning of an immobilizer the display lamp continues to be shone after поворачивания the ignition key in position ON.

At replacement of the module of ignition, replacement of keys or acquisition of an additional key, it is necessary to make procedure of its adaptation of operating elements of system. The procedure essence consists in initialization of an immobilizer and a re-registration of an identification code. System initialization leads to clearing of memory of the module of management then can be registered to four new keys (транспондеров).

Each complete set of keys (no more than 4 pieces) should be registered only on one module of management. Told means that at replacement of the module registration of old keys on the replaceable module is not represented possible and all complete set also is subject to replacement.

Registration of keys should be made in the conditions of a firm car repair shop with application of firm input reader Subaru (SSM) and the special software access to which of privacy reasons is strictly limited.
