FAULT DIAGNOSIS W I T H FIAT LAIMCIA TESTER
For petrol cars fitted with an integrated fuel injection - ignition system and diesel cars with electronic fu­
el injection pump, the Fiat CODE system does not have its own diagnostic socket. To check whether the
system is operating, diagnosis should be conducted on the electronic fuel injection - ignition control
unit (petrol cars) or fuel injection control unit (diesel cars).
The following can be measured with the Fiat Lancia Tester:
Parameters
- STARTING PERMITTED/NOT PERMITTED
This means that the engine control unit has recognized the code permitting engine starting.
- PROGRAMMED/NOT PROGRAMMED STATUS OF ELECTRONIC KEY
The indication NOT PROGRAMMED means that both fuel injection and Fiat CODE control units are
unused (no memorized code).
