When the alarm system is activated, control unit M030 (pins 1, 4 and pins 3, 6 of connector B respectively) activates volumetric sensors K060 (pins 1, 2) and K061 (pins 1, 2).

These sensors may be cut out when control unit M030 (pin 5 connector A) receives an earth signal from switch I130 (pin 6).

Control unit M030 manages (pin 11 connector A) deterrent led E040 (pin 1) and monitors (pin 9 connector A) bonnet lid switch I010 (pin 1).

Front catches N050, N051 (pin 1 or pin 6 if the door lock is fitted with child safety catch) communicates door open/closed status to body computer M001 (pins 4 and 5 connector L respectively).

The opening of the sliding side doors is signalled (pin 1) by the specific switches I018 (left) and I019 (right) to the body computer M001 (pins 34 and 33 connector L respectively).

Electric boot lock N057 is commanded (pin 1) from body computer M001 and also sends (pin 3) a boot lid closure signal (pin 13 connettore L).

The signal coming from the boot lid switch I011 (pin 1) is also transmitted to the Body computer node M001 (pin 10 connector I).

Alarm siren control unit P090 is supplied (pin 3) from body computer node M001 (pin 10 connector B) and receives (pin 2) an activation signal from control unit M030 (pin 2 connector A). The siren is activated even if it is not supplied with power via an internal buffer battery.
