Check the tension of the battery (U>12,3V). If it is necessary, charge the battery.

Check the correct connection of the E.C.U. decoder to the wiring.
Check the supply of the E.C.U. decoder : - mass at pin A8;

- supply (+IC) at pin A9.

Be sure that the diagnostic socket is correctly supplied.
Check the continuity and the isolation of the electric wiring on the pins’ line corresponding to:
