    ENGINE CONTROL UNIT ERRORS (Computer)
    The dashboard receives from the central computer only actual faults
    Vcc = + 5Volts. Gnd = Ground or Frame C.C. = Component connector (this is my guess)

    ECU Error Code 10 Error throttle valve C.C. Vcc
    ECU Error Code 11 throttle valve C.C. Gnd
    ECU Error Code 14 Engine temperature C.C. Vcc
    ECU Error Code 15 Engine temperature C.C Gnd
    ECU Error Code 16 Air temperature C.C. Vcc
    ECU Error Code 17 Air temperature C.C Gnd
    ECU Error Code 20 Low battery
    ECU Error Code 21 Lambda sensor (O2 Sensor in exhaust)
    ECU Error Code 22 Ignition coil 1 C.C. Vcc
    ECU Error Code 23 Ignition coil 1 C.C. Gnd
    ECU Error Code 24 Ignition coil 2 C.C. Vcc
    ECU Error Code 25 Ignition coil 2 C.C. Gnd
    ECU Error Code 26 Injector 1 C.C. Vcc
    ECU Error Code 27 Injector 1 C.C. Gnd
    ECU Error Code 30 Injector 2 C.C. Vcc
    ECU Error Code 31 Injector 2 C.C. Gnd (This is not listed but I suppose that this is the function)
    ECU Error Code 36 Pump relay
    ECU Error Code 37 Local Loop-back
    ECU Error Code 44 Relay starter C.C. Vcc
    ECU Error Code 45 Relay starter C.C. Gnd
    ECU Error Code 46 Cannister C.C Vcc
    ECU Error Code 47 Cannister C.C. Gnd
    ECU Error Code 50 Battery high
    ECU Error Code 51 ECU general
    ECU Error Code 54 Instrument panel
    ECU Error Code 55 Autoadaptation Tito I (I have no idea what this is.)
    ECU Error Code 56 Vehicle speed
    ECU Error Code 60 Stepper C.A.
    ECU Error Code 61 Stepper C.C. Vcc
    ECU Error Code 62 Stepper C.C. Gnd
    ECU Error Code 00 Unknown

    DASHBOARD ERRORS

    DSB 01 Immobiliser fault: key code read but not recognised or key code not read
    DSB 02 Key not present or transponder broken
    DSB 03 Immobiliser fault: Antenna broken (open or short-circuit)
    DSB 04 Immobiliser fault: internal controller fault
    DSB 05 Fuel sensor fault
    DSB 06 Air temperature sensor fault
    DSB 07 Oil sensor fault DSB
    DSB 08 Oil pressure fault

    The dashboard maintains memory of old errors.

    Engine oil sensor faults
    The dashboard will reveal oil pressure faults as well as sensor faults. The oil
    sensor fault is detected with engine stopped and key in on position, if the
    sensor is not conducting (open circuit). This fault is indicated by lightening
    the warning “service” that will remain lit also with engine running
    Abnormal oil pressure is indicated with engine running at an rpm higher than
    2000 rpm and the sensor conducting (shorted). In this case the fault is
    indicated by lighting the icon “oilcan”.
    In both cases codes are stored in the diagnostic memory of the dashboard

    By the way, any idea if:
    Are the error codes sent once & then cancelled by ECU to dashboard special "clear" command / looped every x seconds from the ECU to dashboard?/ once on ignition ON etc or whenever?
