| STEP | CHECK TO BE PERFORMED | REMEDIAL ACTION IF THE CHECK IS NOT OK |
|---|
| 1 | - Connect the Examiner Plus or Smart diagnostic equipment- In the parameters ambient display:*- Engine rpm*- Clutch disc speed- Carry out a road test at a constant speed without gear changes (V » 30 km/h).- Whilst driving, observe the two parameter selected- Check that there are not any significant fluctuations/differences of the clutch rpm signal compared with the engine rpm. | Move on to Step 2 |
| 2 | Rpm sensor wiring checkCheck the continuity/insulation of the wiring between the sensor and the gearbox control unit. | Restore the continuity/insulation of the wiring between the gearbox control unit and the sensor. See E7051 ROBOTIZED GEARBOX |
| 3 | Rpm sensor resistance checkCheck that the rpm sensor resistance is 1150 Ohm ± 10% at 20°C. | Replace the rpm sensor Op. 2127E52 HYDRAULIC SELECTION GEARBOX INPUT SHAFT SPEED SENSOR - R.R. If Ok, replace the robotized gearbox control unit Op. 2127E10 HYDRAULIC SPEED SELECTION SYSTEM CONTROL UNIT - R.R. |
