| STEP | CHECK TO BE PERFORMED | REMEDIAL ACTION IF THE CHECK IS NOT OK |
|---|
| 1 | Battery voltage checkCheck that the battery voltage is greater than 11 V | Restore correct battery charge |
| 2 | Checking the hydraulic circuit pressure- Connect Examiner and take a reading of the hydraulic circuit pressure. With the electric pump off, the pressure should be between 36.5 and 46 bar when the oil temperature is above 20°C- Check gearbox oil level | Restore oil level and check there are no leaks in the system.Renew the seal if there are leaks |
| 3 | Checking the Electric pumpCheck the electric pump protective fuse is intactConnect Examiner and in active diagnosis mode check operation of the electric pump.Shift through the gears until the electric pump is activated and use a clamp ammeter to check that pump consumption is approximately 18 A, with battery voltage at least 11.5 V | Replace the 30 A fuse F37 after having verified the cause of malfunctionReplace the electric pump Op. 2127C30 HYDRAULIC SPEED SELECTION SYSTEM PUMP - R.R. Restore the continuity of the wiring between gearbox control unit and the electric pump See E7051 ROBOTIZED GEARBOX Restore the correct electric pump earth connection See E7051 ROBOTIZED GEARBOX |
