			There are no connection faults (Clutch solenoid current)	Replace the solenoid valve Op. 2127C56and check its operation by carrying out a gear change. Continue to Step 8
8	AFTER THE CHECKS ON FAULTS DETECTED	All OK	Problems met	Operation
	Check that the fault is no longer present	End of diagnosis	The fault persists	Continue to Step 9
9	CHECK THE CLUTCH SENSOR WIRING LAYOUT	All OK	Problems met	Operation
	Check the state of the connections, continuity of the wiring (it is important to pay particular attention to the layout of the clutch position sensor wiring in the engine compartment: the wire must not be too taut, and it must have sufficient slack)	Continue to Step 10	A fault is detected	Repair/replace the part that is not working Continue to Step 10
