FUNCTIONAL DESCRIPTIONThe alarm system is managed by the alarm control unit incorporated in the Body Computer M1, which is supplied - connector A - directly by the battery by the line protected by maxifuse F01 of the engine compartment junction unit B001. The Body Computer M001 receives an ignition-controlled power supply (INT) at pin 11 of connector E. Pin 9 of connector E of M001 provides the Body Computer with a reference earth. The Body Computer M1 receives "door open" input signals at pins 54 and 53 of connector B; they are the same signals that turn on the timed lights The on/off signals arrive from the aerial-receiver of remote control P093, which are connected to pins 31 and 46 of connector F of M001. The bonnet is controlled by switch I10 which is connected to pin 48 of connector B of M1. The boot opening switch located in the lock N57 sends an earth signal to the Body Computer M1 - pin 39 of connector F. The siren P90 receives a power supply from the Body Computer M1, from pin 12 of connector C - via the line protected by fuse F36 - and is connected through the dedicated serial line to pin 56 of connector B. The unit that incorporates the volumetric and anti-tilt sensors K62 is supplied by the Body Computer M1 from pin 12 of connector C via the line protected by fuse F36 and is connected through the dedicated serial line to pin 48 of connector F. The unit also receives a power supply from the ignition-controlled line (INT) protected by fuse F49 M1; the unit contains a button for excluding the two volumetric and anti-tilt control functions; the LED next to the button comes on if they are excluded. |
