P93Receiver aerial for alarm and central locking-
DescriptionThe door locks are operated simultaneously by:the key;the door handles;the button on the dashboard;the remote control.Lock operation is managed by the Body Computer, which controls:the actual state of the locks by means of the signals which arrive from the switches located on the locks themselves (signals also used for timing the lights): in this way, the 'lock' command is only issued when all the doors are properly closed and the locks released; conversely, the 'release' command is only issued when the locks are locked;the switch position. If this position does not agree with the action carried out (e.g. if after the lock command a door is open), a repulsion command is issued, i.e. the opposite manoeuvre is carried out to realign all the locks.several consecutive and complete lock/release manoeuvres: if the control unit detects at least 10-11 manoeuvres within 25 seconds - the system cuts in to limit the manoeuvres: the system remains inhibited in the unlock position for 30 secondsif the battery voltage falls below 8-10 V during a lock/release operation, the system suspends the operation. If battery voltage is lower than 8 V at the outset, no command is issued.The signals coming from the door (and boot) open switches together - when the ignition is on - switch on the specific warning light on the instrument panel. The remote control receiver aerial is connected directly to the Body Computer which contains the electronics of the receiver proper: the remote control in the key has two separate buttons: one controls the door lock, the other the release (a third button controls the boot release 3023317SeeE3046BOOT OPENING ). If within 60 seconds from the lock release command issued via the remote control, the user has not shown his intention to take possession of the car (opening of doors and/or boot and ignition turned on), the locks are automatically LOCKED.The door lock/release button is located on the central panel: if the doors are closed, pressing the button releases them; vice versa if they are open, they are locked; an LED at the back of the button also comes on.The door lock circuit is protected by a special fuse located in the unit under the dashboard.
Functional description The door lock command, inside the Body Computer M1 - pin 1 of connector F - has the supply line protected by fuse F38 in the unit under the dashboard B2 ; it also has a dedicated earth connection: pin 20 of connector F. The Body Computer M1 receives as input:the 'lock' signals from the handles (or key in the lock) at pins 24 (driver's door - N50 ) and 17 (front passenger's door - N51 ) of connector E.the 'release' signals from the handles (or key in the lock) at pins 34 (driver's door - N50 ) and 35 (front passenger's door - N51 ) of connector E.the 'door open' signals at pins 8 (driver's door - N50 ) and 25 (front passenger's doodr - N51 ) of connector E;the signal from the lock/release button, located in the controls unit H12 , at pin 2 of connector D; (the button is lit when the doors are locked by the ignition-dependent line (INT) of fuse F49 of unit B2 );the signals coming from the aerial-receiver P93 , which is connected to pins 21 and 31 of connector A. In accordance with the control logic described above, the Body Computer M1 controls the lock motors of the driver's door N50 and front passenger's door N51 , from pins 10 and 11 of connector F. Via the CAN line, the Body Computer M1 is connected to the instrument panel E50 , to which it sends a signal which, when necessary, lights up the 'doors open' warning light.

Follow these precautions:769768768

5530B18


Follow these precautions.769On batteries with an opticam hydrometer,electrolyte level and battery charge status can be monitored qualitativelyby examining the indicator colour: a light, bright colour indicates low electrolytelevel: top up with distilled water;a dark colour without a green area in thecentre indicates that the electrolyte level is correct but chargeis low: recharge the battery; a dark colour with a green area in themiddle indicates that both electrolyte level and charge status arecorrect: no action is necessary. For further details, see DESCRIPTION ANDOPERATION - 5580.768Proceed as follows.Check the battery voltage without loadusing the test device recommended by the Service outlets (e.g. 'MICRO360'). Depending on the voltage values measured,which define the state of charge of the battery, proceed as follows:If the voltage without load is less than12.10 V, replace the battery (see op.). 5530B10).If the voltage without load is over 12.10V but less than 12.50 V, recharge the battery (see op. 5530B14).If the voltage without load is over 12.50V, the battery is efficient.If necessary, top up the electrolyte asfollows.Carefully remove the cap strip.Top up with distilled and deionized water,taking care not to allow electrolyte to splash out.768
