Immobilizer and Transponder
Operating principle of the immobilizer
When the ignition key is positioned to ON, the decoder into the instrument panel energises the
antenna, which generates an electromagnetic field power-supplying the key transponder. The
Transponder sends the code stored into its ROM, which is received by the antenna and sent to the
decoder. Here the secret code is matched with a second code. If matching is successful, then the
decoder sends a code to the engine control unit (CCM) via special serial line (ISO 9141/5). The engine
control unit checks received code and enables engine start if code is correct.
Immobilizer warning lights and indications
Each time the key is turned from ON to OFF, engine is disabled by the immobilizer.
When the ignition key is turned from OFF to ON, the system will signal the following:
if code is acknowledged, the led (1) will turn on and then off;
if code is not acknowledged, the led (1) and the EOBD light (2) for ignition-injection failure will turn on
and stay on. Engine will not start. Repeat the above procedure but using a different black key.
Caution
When programming the immobilizer as described below, use only the required key and keep the other
keys away otherwise they might interfere.
