with VSS

- The ignition switch is connected to the electronic control module (pin 9). When the key is removed from the ignition switch the electronic control module senses this and immobilizes the car.
- The ignition switch is also connected to pin 10 of the electronic control module, which will then sense the voltage level (+12 V) if the ignition switch is turned to the "ON" position (+15 circuit).

If the car is immobilized it cannot be started until the engine management system has identified the correct code from the remote control unit (otherwise the engine management system will prevent the engine from being started). An alarm will be set off if the anti-theft alarm is armed, that is to say an attempt to start the car will trigger both an alarm and "immobilizing".


Important:
- If the ignition is in the "ON" position (+15), the theft alarm cannot be armed.
- If the ignition switch is turned to the "ON" position (+15 circuit) during the anti-theft alarm delay period, arming of the alarm will be cancelled automatically.
