Functional description The supply controlled by the ignition (INT) for the instrument E50 reaches pin 19 of connector A from the line protected by fuse F1 of the junction unit B1 . The instrument E50 is also supplied directly by the battery - pin 17 of connector A - via the line for the maxifuse J/B1 of B5 protected by fuse F10 of the junction unit B1 . Pin 18 of connector A is earthed (electronic earth).Pin 1 of connector B is earthed (power earth). Pins 2 and 16 of connector A receive signals coming from the fuel gauge, located in the electric pump unit N40 : these signals, processed by the internal electronic device, operate the fuel gauge and the reserve warning light. Insufficient engine oil pressure is signalled to pin 18 of connector C from the earth signal coming from the sensor K30 . The signal from the sensor K20 . reaches pin 13 of connector C and lights up the brake pad wear warning light. Device K32 measures the level of the engine oil during starting: it receives a reference signal from pin 14 of connector A of E50 and sends a signal to pin 10. Signals from handbrake switch I40 and brake fluid level sensor K25 . reach pin 11 of connector A and pin 15 of connector C of E50 and light up the insufficient brake fluid level/handbrake warning light. The same warning light is on - together with the ABS failure warning light - if the ABS control unit detects problems involving the EBD function 2889563SeeE7023ESP . Pin 5 of connector B of E50 receives the 'doors open' signal coming from the integrated services control unit M40, pin 7 of connector A. [also see EL2510]. The inertia switch I50 intervention signal reaches pin 3 of connector A of E50 : under these circumstances the instrument panel produces the appropriate signal. The water in the filter sensor K31 is supplied by the line for fuse B412889410SeeE5050DIESEL ENGINES ELECTRONIC MANAGEMENT and sends a signal to 7 of connector B of E50 . The speedometer sensor K84 located on the gearbox is supplied from the line of fuse B412889410SeeE5050DIESEL ENGINES ELECTRONIC MANAGEMENT and sends a signal to pin 5 of connector A of E50 : this signal, processed by the internal electronic device, operates the vehicle speed indicator and the milometer and the output is available: from pins 30, 31 and 32 of connector A for the engine management control unit, the navigation system, the taxi-meter, etc. The engine rpm signal arrives from the engine management control unit M10 at pin 6 of connector A of E50 : this signal, processed by the internal electronic device, operates the rev counter. A 'fuel consumption' signal, used by the trip computer, reaches pin 7 of connector A of E50 from the engine management control unit M10 .
