| | Test results |
| 1 | ERRORS IN CONTROL UNIT CHECK | All OK | Problems encountered | Operation |
|---|
| Check that there are no errors in the control unit. More specifically:- Absence of accelerator pedal information error- Clutch or engagement solenoids error- Engagement sensor error- Selection solenoid error.- Pump relay error. | End of diagnosis | 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 | Move on to Step 3 | Fault at the connections. | Restore/replace the wiring See E7051 ROBOTIZED GEARBOX |
| The active diagnosis of a solenoid is inconclusive and no wiring errors are detected (clutch and/or engagement solenoid). | Move on to Step 3 |
| 3 | CLUTCH SOLENOID REPLACEMENT | 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 | ENGAGEMENT SOLENOID REPLACEMENT | All OK | Problems encountered | Operation |
|---|
| If this step has been reached during the active diagnosis of the engagement solenoid, replace it Op. 2127C52 ODD AND EVEN GEAR ENGAGEMENT SOLENOIDS - R.R. and check for correct operation | Move on to Step 5 | | |
| 5 | REPLACEMENT OF SENSORS / SOLENOIDS | All OK | Problems encountered | Operation |
|---|
| If no connection / wiring faults are detected and the gear engagement sensor is in error, replace it Op. 2127E42 HYDRAULIC SELECTION GEARBOX SHIFT POSITION SENSOR - R.R. and check that the reading for the position is correct by carrying out a series of gear changes.If no connection / wiring faults are detected and the electro-magnetic brake is in error, replace it Op. 2127C54 GEAR SELECTION SOLENOIDS - R.R. and check it is working correctly. | Move on to Step 6 | | |
| 6 | GEAR LEVER CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the gear lever is working properly, carrying out See Test 2127OL GEAR LEVER CHECK | Move on to Step 7 | The lever states displayed are not correct. | Check the gear lever wiring and switches, repair / replace the part that is not working. |
| The state does not change and/or the word AUTO is not displayed. | Check the wiring and switch, repair / replace the part that is not working. |
| 7 | CORRECT OPERATION CHECK | 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. |
