W/O VSS

The ignition switch is connected to the control module (pin 10) so that the control module is able to sense the voltage (+12 V) if the ignition is turned to the "ON" position (+15). The alarm is set off if the theft alarm is armed. This means that if an attempt is made to start the car. both the alarm and "3-circuit breaking" (immobilizing of starter and fuel pump relays and +15 power supply to the engine management system) are set off.



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