Diagnosis Environment
ECM electronic control unit identification code
The diagnosis instrument consults a storage area of the
electronic control unit, where the identification data are listed.
Then it displays, if available, the identification code, the control
unit and software versions, the date of manufacture and the
ECU configuration data.
In the event that communication with the control unit is
interrupted, you can print the ”Identification code” screen
(where enabled) by selecting the PRINT button.
Consulting the ”Identification code” card is essential in the
event that information is requested from the Service
Department.
Control unit identification code reading
Fault code reading
Faults (memorized by the control unit) are automatically
identified by the diagnosis instrument after actuating
communication with the electronic control unit.
This screen lists the faults or malfunctioning relative to the
components directly connected and managed by the
electronic control unit.
Reading the FAULT CODES (available in the control unit)
Stored fault code reading
Some of the stored and listed faults might be intermittent.
More precisely, some of them might, when being diagnosed,
not be present, yet previously memorized by the control unit
itself (intermittent faults).
This screen also allows you to clear the faults found in the
memory after the repair work has been carried out.
Reading the FAULT CODES (present and intermittent)
Event code reading
This screen lists anomalous faults or malfunctioning of
components not closely related to the engine management
electronic control unit, but which could in any case affect
correct operation of the engine.
Reading the EVENT CODES (out-of-range sensors)
The screen is saved automatically in the ELTRAC
folder. It is advisable to rename the identification file
because it will be overwritten if there is a
connection to the diagnostic socket of another
power unit.
Note — Save key use: pressing the save key the file
of the screen is saved in the ELTRAC folder and a
name will be automatically given to it. The name of
the file includes the hours, minutes and seconds of
when it was saved. The name is univocal and
cannot be overwritten.
