| | Results of the tests |
| 0 | OIL LEVEL CHECK | All OK | Problems met | Operation |
|---|
| Check
the oil level See Test 2127B OIL LEVEL CHECK | Continue to Step 2 | Level below Max reference | Top up the oil levelContinue
to Step 1 |
| Level above Max reference | Reduce to Max levelContinue to Step 2 |
| 1 | CHECK FOR OIL LEAKS | All OK | Problems met | Operation |
|---|
| Check
that there are no oil leaks See Test 2127C CHECK FOR FLUID LEAKS | Continue to Step 2 | Oil leaks detected | Replace/repair the relevant
parts, top up the oil levelContinue to Step 1 |
| 2 | OIL PRESSURE CHECK | All OK | Problems met | Operation |
|---|
| Check
the oil pressure See Test 2127D OIL PRESSURE CHECK  | Neutral for low pressure only exists
if the vehicle is stationary or moving at low speed (about 10-15
km/h) |
| Continue to Step 4 | Pressure < 40 bar | Continue to Step 3 |
| 3 | CHECK PUMP OPERATION | All OK | Problems met | Operation |
|---|
| Check
that the pump is working properly See Test 2127E ELECTRIC PUMP OPERATION CHECK | Continue to Step 4 | Voltage below 11 V | Check the batteryContinue
to Step 3 |
| It is not possible to carry out gear changes from the lever | Activate the 'clutch bleed' service from the Examiner
Plus or Smart to activate the pumpContinue to Step 3 |
| 4 | CHECK ON BRAKE PEDAL SWITCH | All OK | Problems met | Operation |
|---|
| Check
that the brake pedal switch is working See Test 2127F CHECK ON BRAKE PEDAL SWITCH | Continue to Step 6 | The brake pedal switch
is not working properly | Check the state of the connections, the wiring and
the switch. Repair/replace the part that is not working.Continue
to Step 5 |
| 5 | AFTER THE BRAKE PEDAL SWITCH CHECK | All OK | Problems met | Operation |
|---|
| Check
that the fault is no longer present | End of diagnosis | The fault persists | Continue to Step 6 |
| 6 | CONTROL UNIT ERRORS CHECK | All OK | Problems met | Operation |
|---|
| Check that there are no control unit
errors. In particular: - Clutch sensor error
- Clutch solenoid current error
| If this type of error is present, for
safety reasons (at speeds of 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 9 | Presence of one or more
of the errors included in the list | Continue to Step 7 |
| 7 | CHECKS ON FAULTS DETECTED | All OK | Problems met | Operation |
|---|
| Check
the faults See Test 2127I What to do depending on the error' present in the Selespeed control unit No accelerator pedal information. | End of diagnosis | Connections fault (Clutch
sensor and/or Clutch solenoid current) | Repair/replace the wiringContinue
to Step 8 |
| There are no connection faults (Clutch sensor) | Replace the clutch actuator (CSC) and check its operation
by carrying out a gear change.Continue to Step 8 |
| There are no connection faults (Clutch solenoid current) | Replace the solenoid valve Op. 2127C56 and 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 workingContinue to Step 10 |
| 10 | CHECK THAT THE CLUTCH IS NOT DRAGGING | All OK | Problems met | Operation |
|---|
| Check
that the clutch is not dragging See Test 2127K CLUTCH DRIVE CHECK | Continue to Step 12 | The clutch drags | Proceed with checking the
clutch/flywheel kit and, if necessary, replace any components that
do not conform.Continue to Step 11 |
| 11 | AFTER THE INTERVENTION ON
THE CLUTCH KIT | All OK | Problems met | Operation |
|---|
| Check
that the fault is no longer present | End of diagnosis | The fault persists | Continue to Step 12 |
| 12 | CHECK THAT THERE ARE NO ERRORS ON
OTHER SYSTEMS | All
OK | Problems
met | Operation |
|---|
| Check
that there are no errors or any problems in other vehicle systems | Continue to Step 13 | There are faults detected | Continue in accordance with
the instructions for the diagnostic equipment |
| 13 | THE FAULT PERSISTS | All OK | Problems met | Operation |
|---|
| Check
that the fault is no longer present | End of diagnosis | Fault persists | Search for the
fault starting from another symptom' |
