ALARM OPERATIONAL DESCRIPTION

Operational Description

The alarm control unit M030 receives an ignition-controlled supply at pin 7 connector A from the body computer node M001 from pin 1 connector A.

Pin 4 connector A receives a reference earth from the body computer node M001 from pin 2 connector A.

The control unit M030 communicates, from pins 6, 10, 12, via the CAN, with the body computer node, at pins 5, 4, 6 connector A of M001.

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

These sensors can be cut out when control unit M030, at pin 5 connector A, receives a negative signal from switch I030.

Pin 11 connector A of control unit M030 manages deterrene led E040.

Bonnet lid switch I010 is connected to alarm control unit M030 at pin 9 connector A.

The front and rear door and boot switches are connected to the body computer node M001 and from there, via the CAN, to the alarm control unit M030, see also

See E3040 CENTRAL LOCKING

The front door locks N050 and N051 communicate with the body computer M001, at pins 4 and 5 of connector L, informing it of the state of the door (open/closed).

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

The boot lid closed signal for the lock N057 is supplied to pin 16 connector I of the body computer node M001; the body computer node receives the signal coming from the boot lid switch I011 at pin 17 of the same connector.

Alarm siren control unit P090 supplied at pin 3 from body computer node M001, pin 12 connector B, from a line protected by fuse F11, receives, at pin 2, an activation signal from control unit M030, from pin 2 connector A. The siren is activated even when it is deprived of a power supply from the body computer node due to a buffer battery inside.

Alarm system activation is indicated by the turn signals coming on. The body computernode M001 operates the switching on of the lights from pins 13, 14 connector H
