ALAJ:IM · - E.LE.CtRONIC ANTI-THEFT SYSTEM

GENERAL •

The vehicle is equipped with a remote control el&c· tronic .antl-th&ft sys1em. The remote con"trola!soactuates the centralized door kicklunlocl< system. lhs arrti·theH system consis1s o1 an e·rectronic unit a syren iocated in 1he right side of trun~. and a remote oontror used to actTvaieJdeactivate the system. 'The syten is

1poweted by a dedicated battery and is

provided with an ON/OFF key. Activation of the anti·theR system Is indicated by11~hing

of a ladonthe central console, actuation oftne centrali'zed door lod< and iUuminatic·n tor a iew seconds e>fthe tum signal lamps .• Activation oft he .ami-thefts yste m also looks. t"& engine rgnilion clrouit. O·eactivation of the .anti·thef1 system is Indicated by illum!natlon or the turn signal lamps, centralizedunlo;Ck.~

ing of door and switching off of led on the central console_ The system is protected by 1ree fuse G258 (15A) ANTITHEFT SYSTEM.

OPERATIONAL DESCRIPTION

Ttle 12Y power sup,ply line Is connected directiy 10 the

anti·the-11 sy.s!·em syren 011 , to p~ns 5 a!'}(! 1 2 ot 'he antitheft contror unlt N45 througt, tha fl/'e& fuse G2SS, and to led 031 on the central console. Activation ot 1he anti-theft system is obtained by directing the remote control towards the vehicle and pressing the

control push button; the remote control is provided with and Indicator light wliicn muminates any Ume the control pushbutton is pressed.!. The conuol unf! N45 provides the following· 1undions when the anti-theft system Is .actlvated:

~ Fjashing· of led D31 (pin B o1 control unit}.

• Actl.lation of centralized door lock (pins 16 ar.d 18).

- Flashing of thetoortumsigoallamps (pins 1,3, 1 Sand 17) .

• Engagement of e:ngine ignitijon circui11ock. (pin 2).

When theantHhe·tl system is activated, openingo1doors, engine hood or trunk lid is sensed by the c:cmrcl unit N45, ~ith conse<~uent a.ctivation of siren 0 11. lnlormati<~n

about opening ot doors, engine hOod and tnmk lid is trasmitted to the control un~ by dedicated switches. Whell a door is opened, the corresponding switch opens and supplies a "door open" input to pin 3 of control unit N45. When the engine hOod or ·tihe trun~ lid are opened, 1heccrrespon01ing switches H44an<J 1124close, and con· nect to ground pins 10 0 ( 7 ot tne control unit N45. W~h the ignition key inserte<i , the battery power is supplied to pin 14 o1 control unit N45, 1hus allowing inhibition

of the receiver to prevent accidental a.ctivat1ons.

I ftuee w1ndsh1eld w1pers operating modes are available.:

position t ( •!f ): intermittent position. with five possible adjustments

position 2 ( • ) : continuous operation, normal speed.

position 3 <:J: continuous operation, high speed

To operate the windshield washer pull the multiple switch iever, located to the right of the steering wheel, towards the steering wheeL Actuation of the windshield washer with position lamps ON automatically actuates the head lamp washer.

NOTE In case of lack oi washer fluid, do not actuate the electric pump to avoid damage.

The system is protected by three fuses in the fuse box G1, as follows:

fuse F1 ( 1 OA) POSITION LAMP

fuse F10 (20A) WINDSHIELD WASHER/WIPER

OPERATIONAL DESCRIPTION

Battery power, available when the ignition key 1s set to RUN, is applied through the fuse F10 (windshield wiper and washer) to the windshield wiper motor and control unit P27, and to the multiple switch lever 868. Moving the multiple switch lever to .... position, power is applied to the windshield wiper moto~nd control unit P27 through pin 1 E of the multiple switch unit. The motor P27 actuates the wiper in the intermittent mode and a five position potentiometer on the multiple switch lever 868 connected to pin 5 olthe control unit P27 allows intermittent frequency adjustment. Moving the multiple switch lever to • position, power is applied to the control unit P27 through pin 48 of the multiple switch unit. In this case the motor P27 actuates the· wipers in the continuous mode normal speed. Moving the multiple switch lever to: position. power is applied to the control unit P27 through pin 2C of the multiple switch unit. In this case the motor P27 actuates the wipers in the continuous mode high speed. When the windshield washer is actuated. t 2V is applied, through pin 3C of multiple switch 868, to the head lamp washertimer N12, to the windshield washer electric pump P19 and to pin 7 of the motor P27 to momentarily operate the windshield wipers. Actuation of timer N12 applies 12V to the head lamp washer electric pump P20 only if the position lamps are ON. The power line to pump P20 is protected by the head lamp washer fuse F17.
