This function is used to determine that injected amount AdBlue matches reference values. The test may only be run if the dosing module has been removed and aimed into a measuring container.
The results for the different positions are reached by opening the dosing valve for varying times and with varying high flows.
The amount of injected AdBlue shall be + / - 10% of the reference value.
Test conditions:
Ignition on, engine off.
Procedure:
Select desired position and press "OK" to start the test.
Reference values:
Injection position | Flow (g/h) | Injection time (s) | Quantity (g) |
Position 0 | 6000 | 12 | 20 |
Position 1 | 5000 | 14,4 | 20 |
Position 2 | 4000 | 18 | 20 |
Position 3 | 3000 | 24 | 20 |
Position 4 | 2000 | 36 | 20 |
Position 5 | 1000 | 72 | 20 |
Position 6 | 500 | 144 | 20 |
Position 7 | 6000 | 60 | 100 |
Position 8 | 3000 | 120 | 100 |
Position 9 | 500 | 720 | 100 |
The function is done.
If the function fails, check the test conditions and repair any faults.
