Ignition






The ignition switch is connected to the control module (pin 10) so that the control module senses 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 (blocking of operating voltage to the starter and fuel pump relays and +15 to the engine control module) are set off.



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