DESCRIPTION - DIRECTION INDICATORS / HAZARD WARNING LIGHTS - Fiat GRANDE PUNTO 1.3 Multijet
The left and right direction indicators are switched on by raising or lowering the special stalk lever on the left of the steering column switch unit; the function is activated with the key-on.The hazard warning lights (left and right direction indicators operated simultaneously) are activated via a button in the centre of the dashboard and all the direction indicators are activated at the same time. An LED at the back of the control button also comes on synchronized with the flashing of the exterior lights. This function is always activated for safety reasons.The engagement of the direction indicators / hazard warning lights is managed by the Body Computer which also controls the flashing frequency which is sent to the other nodes via the CAN serial network. In this way the two direction indicator warning lights in the instrument panel are also switched on; in addition, the system provides a low frequency acoustic signal in conjunction with the activation of the lights.The direction indicators check function checks that the lights are working properly: the following are checked for each of the two circuit (right side branch and vehicle left side):- 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: in the instrument panel: a special failure warning light comes on and, at the same time, the information is shown in the display only at the key on.In addition, at the same time as a failure warning light comes on, the flashing frequency of the visual indication in the display and the acoustic signal increases; the flashing frequency of the exterior lights and the LED in the emergency button, on the other hand, remains unchanged.
FUNCTIONAL DESCRIPTION - DIRECTION INDICATORS / HAZARD WARNING LIGHTS - Fiat GRANDE PUNTO 1.3 Multijet
A single signal (earth) is sent from stalk unit H5 to Body Computer M1 to manage the right and left turn signals: from pin 1 of H5 to pin 51 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.The hazard light activation signal (earth) reaches pin 23 of connector D of M1 from control button in unit H90.The reference earth reaches pin 5 of H5 from pin 49 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.Body Computer M1 controls side turn signals F20 (left) and F21 (right) from pins 19 and 20 of connector C - front turn signals F10 (left) and F11 (right) from pins 9 and 1 of connector C -and rear turn signals F30 (left) F31 (right) - from pins 20 and 11 of connector C.The signal (positive) is sent from pin 10 of connector B of M1 to light up the LED in the control button H90.The Body Computer M1 is connected, via the CAN line, to the instrument panel E50 to manage the "direction indicator" warning lights, the buzzer and, if there is a problem in the circuit, the "lights failure" warning light.
