| 0 | PRELIMINARY CHECKS | All OK | Problems encountered | Operation |
|---|
| Disconnect the throttle casing actuator cable loom connector in the engine management junction unit side.Connect a T bridge between the motor wiring and the throttle casing actuator.Using the diagnostic equipment in voltmeter mode, check that at Pin 2 of the actuator See N075 BUILT-IN THROTTLE BODY ACTUATORthere is a voltage of more than 11 V | Move on to Step 1 | The supply voltage for the throttle casing actuator is less than 11 V | Continue as instructed in the See Test 5530BB BATTERY VOLTAGE CHECK |
| 1 | THROTTLE CASING CHECK | All OK | Problems encountered | Operation |
|---|
| Remove the throttle casing actuator Op. 1060G50 THROTTLE BODY - R.R and check that there are no foreign bodies preventing movement between 0 and 26° | Move on to Step 2 | Foreign bodies detected as present | Remove the foreign bodies and check that the actuator is working properly. If the latter is too spoilt, replace it Op. 1060G50 THROTTLE BODY - R.R |
| 2 | CLEANING THROTTLE CASING | All OK | Problems encountered | Operation |
|---|
| Check that the inside of the throttle casing actuator duct is not dirty/fouled in such a way as to prevent correct movement | Move on to Step 3 | Excessive fouling/dirtiness | Clean the dirty areas with a small paintbrush soaked in diesel fuel. | Avoid submerging the throttle casing because the internal electrical components could be damaged |
|
| 3 | THROTTLE CASING REPLACEMENT | All OK | Problems encountered | Operation |
|---|
| Replace the throttle casing actuator Op. 1060G50 THROTTLE BODY - R.R | End of diagnosis | - | - |
