Functional description

The alarm system is controlled by alarm control unit M30 integral with the siren. The control unit is supplied directly from the battery to pin 3 of connector A by a line protected by fuse F17 and pin 7 of connector B (power supply to turn signals) by a line protected by fuse F8 ; both fuses are located in the junction unit B1 . The supply controlled by the ignition (INT/A) reaches pin 12 of connector B of control unit M30 through a line protected by fuse F5 of control unit B1 . Pin 9 of connector A is earthed ( C31 ). Control unit M30 controls door closure via switches N50, N55, N51, N56, which send an earth signal to pins 8, 15, 9 and 16 of connector B respectively when the door is open (the same switches turn on the door open indication leds (  See E2510  COURTESY LIGHTS ). Switch N50 is also used as an automatic transmission management safety system ( See E7050 AUTOMATIC TRANSMISSION ). Switches N50, N55, N51 and N56 are also used by the door lock management system ( See E3040 CENTRAL LOCKING ). The bonnet lid is controlled by switch I10, which is connected to pin 18 of connector B, while the boot lid is controlled by switch I11, which is connected to pin 17 of connector B (the same switch turns on the boot light ( See E2520 GLOVE COMPARTMENT LIGHT - LUGGAGE COMPARTMENT LIGHT - SUN VISOR LIGHT ). Volumetric sensor unit K62 receives supply and earth signals from pins 8 and 11 of connector A of M30, and sends on the alarm control signal to pin 12 of connector A of M30. Pin 1 of connector A of M30 sends alarm led control signal E40 . Pins 1 and 2 of connector B of M30 produce control signals for turn signals (  See E2020  DIRECTION INDICATORS / HAZARD WARNING LIGHTS ). Remote control receiver M35 is supplied directly from the battery at pin 3 via fuse F17 of control unit B1 . An ignition-operated power supply (INT/A) reaches pin 7 of M35 via a line protected by fuse F5 of control unit B1 . pin 4 is earthed C30 . M35 (pins 5 and 6) issue door lock and door release signals (  See E3040  CENTRAL LOCKING ). M35 pin 8 emits a signal to turn on interior courtesy light ( See E2510 COURTESY LIGHTS ); Pin 10 emits a signal to open/close the boot and fuel filler flap. M35 pin 1 sends a control signal to relay J43 (turn signals/hazard lights) to turn on the flashing side lights upon alarm system activation via its internal contacts. Control unit M30 and receiver M35 are both equipped with a self-diagnostic unit that may be used by connecting the unit to connector R10 via pin 11. This receives signals from pin 6 of connector A of M30 and pin 2 of remote control receiver M35 . This serial line also acts as a connection between M30 and M35 .
