DESCRIPTION - SIDE LIGHTS / NO. PLATE LIGHTS - Fiat GRANDE PUNTO 1.3 Multijet
The side lights come on when the ring nut on the steering column switch unit left lever is turned to the first position.The switching on of the side lights is managed by the Body Computer.The side light control function takes place with the key ON, or with the key OFF for parking lights and follow-me-home function.The number plate light and numerous other interior lights for lighting the passenger compartment, instruments and controls are activated together with the side lights (these are described and explained in the wiring diagrams for the relevant components), in particular:Activation/deactivation information is sent via the CAN network: in this way, the side lights warning light in the instrument panel is also activated. The instrument panel also activates the nightime lighting.This function makes it possible to switch on the side lights and the no. plate lights with the ignition OFF, to signal the presence of the vehicle whilst it is parked. The activation only takes place at the key OFF by manoeuvring the steering column switch unit ring nut.The function is deactivated by moving the steering column switch unit lights ring nut to the OFF position or at the vehicle Key ON. This last operation resets the function and the Body Computer controls the lights depending on the command selected using the steering column switch unit ring nut.The "Follow me home" function allows the dipped headlamps and the side lights to remain on even after the engine has been switched off (key in OFF position) for a period of 30 seconds or multiples thereof. The side lights warning light in the instrument panel signals that the lights have remained on. It is turned on using the lever in the same way as for activating the flasher within 2 minutes of the ignition being switched OFF: each time the lever is operated the length of time the lights remain on is increased by 30 seconds, up to a maximum of 210 seconds. Inserting the TEG or keeping the flasher lever pulled for more than 2 seconds eliminates the function.The correct operation of the lights is checked by the side lights and no. plate lights check function: the following is checked for each of the circuits:- circuit open or bulb missing- short-circuit to earth (bulb s.c. or wiring s.c. to earth)- short circuit to battery voltage (wiring short circuited to Vbatt)When one of the situations described above is ascertained, the Body Computer makes the failure status available to the CAN: a special "lights failure" warning light comes on in the instrument panel and, at the same time, the information is shown in the display.
FUNCTIONAL DESCRIPTION - SIDE LIGHTS / NO. PLATE LIGHTS - Fiat GRANDE PUNTO 1.3 Multijet
A single signal (earth) is sent from stalk unit H5 to Body Computer M1 to manage both side lights and low beams: from pin 3 of H5 to pin 38 of connector D of M1; the signal sent is coded through various resistance partitions so that multiple information is sent to the Body Computer via a single connection.The reference earth reaches pin 10 of H5 from pin 34 of connector D of M1.IBody Computer M1 - connector G - is supplied directly by the battery from a line protected by maxifuse F2 of engine compartment control unit B1; it is suppiled via the ignition (INT) at pin 32 of connector D; pin 10 of connector H of M1 supplies a reference earth to the Body Computer.The Body Computer M1 controls the supply for the front side lights F10 (left) and F11 (right) from pin 13 of connector C, for the rear side lights F30 (left) and F31 (right) and the number plate lights F50 and F51 from pins 17, 7, 14 of connector C.Via the CAN line, the Body Computer M1 is connected to instrument panel E50 to manage the side lights on warning light and, if faults are detected in the circuit or in the bulbs, the lights failure warning light; in the vent of a fault with the dusk sensor there is a specific signal.
