The control unit is provided with a self-diagnosis
system connected to an indicator light in the in-
strument panel.
Failures are detected and restored by the diag-
nostic tester.
In any case, when the fault is no longer present,
the data storage is automatically cleared after 16
cycles of use (cold start, running at regular engine
temperature, stop).
The diagnostic tester is also required to adjust the
idle mixture.
