Results of the tests
0CONTROL UNIT ERRORS CHECKAll OKProblems metOperation

Check that there are no control unit errors. In particular:

  • Clutch sensor error
  • Clutch solenoid current error
Vehicle speed error
in the presence of Clutch sensor and/or clutch solenoid valve current errors, for safety reasons (at speeds below 5 km/h) the Selespeed control unit could request the injection control unit to switch off the engine; it is therefore advisable to carry out an engine management fault diagnosis.
Continue to Step 4Presence of one or more of the errors included in the list Continue to Step 1
1CHECKS ON FAULTS DETECTEDAll OKProblems metOperation

The active diganosis is not successful and there are no faults detected at the wiring (Clutch solenoid valve) Continue to Step 2
2AFTER THE SOLENOID VALVE ACTIVE DIAGNOSISAll OKProblems metOperation
If this step has been reached for the active diagnosis of the clutch solenoid valve, replace it Op.   2127C56  and check the operation by carrying out a C.M.Continue to Step 3.
3AFTER THE CHECKS ON THE FAULTS DETECTEDAll OKProblems metOperation

Check the correct operation of the pump as described in See Test   2127E  ELECTRIC PUMP OPERATION CHECK Continue to Step 8Voltage below 11 V Check the batteryContinue to Step 7
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 pumpContinue to Step 8
8CHECK THE LAYOUT OF THE CLUTCH SENSOR WIRINGAll OKProblems metOperation
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 9There is a fault Repair/replace the part that is not workingContinue to Step 9
9CHECK THAT THE CLUTCH IS NOT DRAGGINGAll OKProblems metOperation
Check that the clutch is not dragging following See Test   2127K  CLUTCH DRIVE CHECK Continue to Step 10The clutch drags Proceed with checking the clutch/flywheel kit and, if necessary, replace any components that do not conform.
