RESET PROCEDURE
If the Marelli control unit or the throttle body is replaced, do not start the engine within the 3 seconds
after the key is set to ON; during this time the control unit carries out the throttle self-learning process:
then make sure that the throttle self-learning status reads: carried out. If the indication is "Not carried
out", delete any possible errors present in the vehicle. Carry out Throttle self-learning process on the
adjustable parameters screen page (screwdriver and hammer), and check again that the throttle self-
learning status reads: carried out.
