DESCRIPTION - ALARM - Alfa Romeo 159 2.2 JTS Da 01/06
The alarm system offers the vehicle anti-intrusion protection of the following types: volumetric, perimeter, anti-tilt and surveillance of cutting the supply leads.System operation is co-ordinated by the Body Computer, wihch sends/receives commands from external modules via the special serial line.The system is turned on/off by means of a remote control interfaced with a receiver in the Body Computer, the remote control unit and the receiver are radio controlled.The volumetric and anti-tilt protection can be excluded by operating a button in the front courtesy light.After one theft attempt, a flashing code emitted by the deterrent warning light indicates the detecting sensor: this warning light also indicates the sending unit battery charge status.The control unit is equipped with a self-diagnostic function which detects and memorises faults and problems in the control unit and system components; in addition, it checks the condition of the connecting cables and saves the number of activations and times the alarm has been operated.The control unit operating logic can be modified in order to satisfy the legal requirements which govern the use of alarm systems in the various markets.For more detailsThe alarm siren is located at the front, under the wheel arch liner on the left of the engine compartment.The door lock system switches are used to monitor the doors and boot. A special separate switch detects bonnet closure.The volumetric sensors check that there are no intrustions in the vehicle. They are located in the front courtesy light: they consist of a transmitter and a receiver: the wave transmitted by one transmitter must reach the receiver of the other sensor and viceversa: otherwise an alarm signal is sent to the control unit.The anti-tilt sensor, is located in the front courtesy light; it detects the slightest variation in the angle of the vehicle in relation to either the longitudinal axis or the vertical axis.By pressing the special button next to the sensors, both sensors can be switched on/off simultaneously; with the sensors excluded an LED next to the button comes on.The deterrent LED is located to the side of the driver''s door safety knob: it signals the "central locking" functionWith the alarm on the LED flashes at 0.8 Hz to indicate that the vehicle is locked.
FUNCTIONAL DESCRIPTION - ALARM - Alfa Romeo 159 2.2 JTS Da 01/06
The alarm system is managed by the alarm control unit integrated in the Body Computer M1: it is supplied by the battery from the line for the maxifuse of B99 - pin 18 of connector F and by the line protected by fuse F39 - pin 17 of connector F; the ignition-controlled supply (INT) reaches pin 9.The Body Computer M1 receives "door open" input signals at pin 8 (driver''s front door), pin 25 (passenger front door), pin 16 (left rear door) and 26 (right rear door) of connector D; these same signals switch on the timed lights.The bonnet is controlled by switch I10 which is connected to pin 24 of connector B of M1.The boot opening switch located in the lock N57 sends an earth signal to the Body Computer M1 - pin 36 of connector E; the same signal is used to switch on the boot courtesy light.The siren P90 receives a power supply from the Body Computer M1, from pin 34 of connector B - line protected by fuse F30 of junction unit B2 and is connected through the dedicated serial line to pin 25 of connector B.The unit that includes the volumetric and anti-tilt sensors, located in the front courtesy light G10 - connector C and F - receives a power supply from the Body Computer M1, from pin 27 of connector E - line protected by fuse F30 of junction unit B2 - and is connected via the dedicated serial line to pin 7 of connector D.The unit also receives a power supply from the ignition-controlled line (INT) protected by fuse F49 of the junction unit under the dashboard B2; the courtesy light contains two buttons for excluding the volumetric and anti-tilt control function and the LED comes on if they are excluded.The deterrent LED E40 located in the driver''s front door is connected to pins 6 and 8 of connector C of M66 and from there, via the CAN, to the Body Computer M1.
