THE VEHICLE DOES NOT RUN

1.2 8v

The engine does not start

The display shows the gear engaged but will not go into neutral to allow starting

Preliminary check: If during engine starting you notice that the starter motor works normally, the problem is caused by other systems (engine management, ABS, fuel pump). Reference is made to the specific diagnoses.

If the starter motor does not turn (after checking its operation and the relevant electrical circuit), continue with the next diagnostic chart

0	CONTROL UNIT ERRORS CHECK	All OK	Problems met	Operation
		Results of the tests
	Check that there are no control unit errors. In particular: Clutch sensor error Clutch solenoid current error Pump relay error Load relay error Selespeed pump error Engagement sensor error Microprocessor 2 error	Continue to Step 4	Presence of one or more of the errors included in the list	Continue to Step 1
1	CHECKS ON FAULTS DETECTED	All OK	Problems met	Operation
	Check the faults according to the See Test 2127I What to do for error in Selespeed control unit	Continue to Step 3	Faulty connections (Clutch sensor, Pump relay, Load relay, Selespeed pump and/or Engagement sensor)	Repair/replace the wiring Continue to Step 3
			The active diganosis is not successful and there are no faults detected at the wiring (Clutch solenoid valve)	Continue to Step 2
			Faulty pump relay and/or fuse (Selespeed pump)	Replace the component Continue to Step 3
			Faults on pump winding (Selespeed pump)	Replace the component Op. 2127C30 Continue to Step 3
			Replace the Robotized Gearbox control unit (Microprocessor error 2)	Continue to Step 3
2	AFTER THE SOLENOID VALVE ACTIVE DIAGNOSIS	All OK	Problems met	Operation
	If this step has been reached for the active diagnosis of the clutch solenoid valve, replace it Op. 2127C56and check the operation by carrying out a C.M.	Continue to Step 3
3	SENSOR REPLACEMENT	All OK	Problems met	Operation
	If there is a gear engagement sensor error and no faults are detected at the connections/wiring, replace it Op. 2127E42and check that the position reading is correct by carrying out a series of C.M.	Continue to Step 4
4	AFTER THE CHECKS ON THE FAULTS DETECTED	All OK	Problems met	Operation
	Check that the fault is no longer present	End of diagnosis	The fault persists	Continue to Step 5
5	OIL LEVEL CHECK	All OK	Problems met	Operation
	Check the oil level as described in See Test 2127B OIL LEVEL CHECK	Continue to Step 7	Level below the Max reference	Top up the oil level Continue to Step 6
		Continue to Step 7	Level above the Max reference	Reduce to the Max level Continue to Step 7
6	CHECK FOR OIL LEAKS	All OK	Problems met	Operation
	Check that there are no oil leaks as described in See Test 2127C CHECK FOR OIL LEAKS	Continue to Step 7	OIl leaks detected	Replace/repair the parts concerned, and top up the oil level Continue to Step 6
7	OIL PRESSURE CHECK	All OK	Problems met	Operation
	Check the oil pressure as described in See Test 2127D OIL PRESSURE CHECK	Continue to Step 9	Pressure < 40 bar	Continue to Step 8
8	ELECTRIC PUMP OPERATION CHECK	All OK	Problems met	Operation
	Check the correct operation of the pump as described in See Test 2127E ELECTRIC PUMP OPERATION CHECK	Continue to Step 9	Voltage below 11 V	Check the battery Continue to Step 8
		Continue to Step 9	It is not possible to make gear changes from the lever	Activate the 'clutch bleed' service from the Examiner Plus or Smart to activate the pump Continue to Step 9
9	CHECK THE LAYOUT OF THE CLUTCH SENSOR WIRING	All OK	Problems met	Operation
	Check the state of the connections, continuity of the wiring (it is important to pay particular 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 9	There is a fault	Repair/replace the part that is not working Continue to Step 10
10	CHECK THAT THE FAULT IS NO LONGER PRESENT	All OK	Problems met	Operation
	Check that the fault is no longer present	End of diagnosis	The fault persists	Contact Technical Service for further information on the problem
