FUNCTIONAL DESCRIPTION - TRIP COMPUTER - Fiat 500 1.3 Multijet
The ignition-operated power supply (INT) for instrument panel E050 reaches pin 3 via a line protected by fuse F37 of Body Computer M001 (pin 7 of connector E); the direct battery power supply reaches pin 2 of E050 via a line protected by fuse F53 of the Body Computer (pin 14 of connector E).Pin 1 of instrument panel E050 is connected to driver-side dashboard earth C015.Body Computer M001 receives a direct battery power supply (pin 1 of connector A) protected by fuse F01 of engine compartment junction unit B001 (pin 18 of connector B); it also receives an ignition-operated power supply (INT) at pin 11 of connector E.Body Computer M001 is also connected to driver-side dashboard earth C015 via pins 9 and 10 of connector E.Instrument panel E050 is connected from pins 5 and 6 with Body Computer M001 (pins 18 and 20 of connector D) and via the latter to the entire CAN.Body Computer M001 (pins 44 and 45 of connector B) receives the speedometer signal from braking system control unit M051 (pins 26 and 14) via the C-CAN, and forwards it to instrument panel E050.The signal relating to the fuel level is managed according to the data provided by the level detector located in electric fuel pump unit N040. The Body Computer provides the sensor with a reference earth (pin 17 of connector F) and receives a proportional signal at pin 4 of the same connector, and forwards it to instrument panel E050 via the B-CAN.Engine management control unit M010 sends the signal coming from engine rpm sensor K046 to the instrument panel via the CAN.
