Immobilizer operating principle
At key-on (switching on the instrument panel by turning the key) the decoder (incorporated in the instrument panel) activates the
antenna, which emits an electromagnetic field that serves to power the transponder in the key grip. The transponder responds
by transmitting the code that is stored on its internal ROM memory, and which is picked up by the antenna and relayed to the
decoder. Here the transponder code is compared to a second code. If the outcome is positive, the decoder sends a further code
to the engine ECU over a dedicated serial line (ISO 9141/5). The ECU checks the code received and, if the result of this check is
positive, engine starting is enabled.
Warning light signals and immobilizer indications
Whenever the ignition key is turned from ON to OFF, the immobilizer system activates the engine start protection system.
When the engine is started and the key is turned from OFF to ON, the system generates the following signals:
- if the code is recognised, the protection system releases the engine lock. When you press the START button (C), the engine
starts.
- pressing button (1) in position "▼" displays the "Error IMMO" message, indicating the the code has not been recognised. In
this case, it is advisable to turn the ignition key back to OFF and then to ON again. If the engine still does not start, try using
another black key.
