| | Test results |
| 1 | ERRORS IN AUTOMATED GEARBOX CONTROL UNIT CHECK | All OK | Problems encountered | Operation |
|---|
| Check that there are no errors in the automated gearbox control unit. More specifically:- Clutch sensor error- Clutch solenoid current error- Pump relay error- Load relay error- Automated Gearbox electric pump error | Move on to Step 4 | One or more errors on the list are present | Move on to Step 2 |
| 2 | CHECKS ON FAULTS ENCOUNTERED | All OK | Problems encountered | Operation |
|---|
| Check the faults, carrying out See Test 2127OI WHAT TO DO DEPENDING ON THE ERROR PRESENT IN THE ROBOTIZED GEARBOX CONTROL UNIT | End of diagnosis | Faults at the connections (Clutch sensor, Pump relay, Load relay and/or Automated Gearbox Electric Pump) | Restore/replace the wiring See E7051 ROBOTIZED GEARBOX |
| The active diagnosis is inconclusive and no wiring errors are detected (Clutch solenoid) | Move on to Step 3 |
| Fuse and/or electric pump relay fault (Automated Gearbox electric pump) | Replace the component See E7051 ROBOTIZED GEARBOX and move on to Step 4 |
| Electric pump winding faults (Automated Gearbox Electric Pump) | Replace the component Op. 2127C30 HYDRAULIC SPEED SELECTION SYSTEM PUMP - R.R. |
| 3 | AFTER THE ACTIVE DIAGNOSIS ON THE SOLENOIDS | All OK | Problems encountered | Operation |
|---|
| If this step has been reached during the active diagnosis of the clutch solenoid, replace it Op. 2127C56 CLUTCH CONTROL SOLENOID - R.R. and check it is working correctly by carrying out a gear change. | Move on to Step 4 | | |
| 4 | FLUID LEVEL CHECK | All OK | Problems encountered | Operation |
|---|
| Check the fluid level, carrying out See Test 2127OB FLUID LEVEL CHECK | Move on to Step 6 | Level lower than Max mark | Top up and move on to Step 5 |
| Level above Max mark | Bring to Max level and move on to step 6 |
| 5 | FLUID LEAKS CHECK | All OK | Problems encountered | Operation |
|---|
| Check there are no leaks, carrying out See Test 2127OC FLUID LEAKS CHECK | Move on to Step 6 | Fluid leaks detected | Repair/replace the parts involved, top up the fluid and move on to step 6 |
| 6 | FLUID PRESSURE CHECK | All OK | Problems encountered | Operation |
|---|
| Check the fluid pressure, carrying out See Test 2127OD FLUID PRESSURE CHECK | Move on to Step 9 | Pressure < 40 bar | Move on to Step 7 |
| 7 | PRESSURE SENSOR CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the sensor is working properly, carrying out See Test | Move on to Step 8 | Pressure sensor not working | Replace the sensor Op. 2127E50 HYDRAULIC SELECTION GEARBOX CIRCUIT PRESSURE SENSOR - R.R. |
| 8 | ELECTRIC PUMP OPERATION CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the electric pump is working properly by carrying out See Test 2127OE ELECTRIC PUMP OPERATION CHECK | Move on to Step 9 | Voltage less than 11 V | Restore correct battery voltage. |
| It is not possible to shift gears using the lever | Activate the "bleed clutch" function from Examiner Plus or Smart to activate the electric pump |
| 9 | CLUTCH SENSOR WIRING LAYOUT CHECK | All OK | Problems encountered | Operation |
|---|
| Check the condition of the connections, the continuity of the wiring (it is important to pay particular attention to the clutch position sensor wiring layout in the engine compartment: the cable should not be too tight, it must have sufficient clearance) | Move on to Step 10 | A fault is detected. | Restore/replace the part that is not working. |
| 10 | CHECK THAT THE FAULT IS NO LONGER PRESENT | All OK | Problems encountered | Operation |
|---|
| Check that the fault is no longer present | End of diagnosis | The fault persists. | Contact technical service for further information on the problem |
