H I CHECK OPERATION OF ENGINE CONTROL SYSTEMS (using the autodiagnostic socket)
A complete electronic fault diagnosis of the injection/ignition system can be carried out by connecting
the Fiat/Lancia Tester or the SDC or Examiner stations to the diagnostic socket.
The system is also equipped with an autodiagnostic function which recognizes, memorizes and signals
any failures.
If a fault is detected and confirmed it is permanently memorized and the relevant sensor is excluded from
the system until it is repaired.
When a fault is detected and confirmed the warning light in the dashboard usually comes on: when the
fault is repaired the light goes out.
Working with the Fiat/Lancia Tester or the SDC or the Examiner it is possible to carry out a complete
system fault diagnosis which consists of three stages:
1. display of a series of functional parameters;
2. display of the errors or their cancellinge;
3. activation of certain actuators (active diagnosis).
Unlike the Fiat/Lancia Tester, the SDC and Examiner equipment use a "touch screen" type display
which is easy to use and can display several parameters simultaneously; a single CD ROM, which can be
periodically updated, makes it possible to carry out fault diagnosis for electronic systems on all Group
vehicle models. Also, if connected to a printer, the results of the fault diagnosis can be certified. In addi­
tion to the diagnostic functions these pieces of equipment have powerful integrated measuring instru­
ments.
