Test is running as follows:
Step 1
– Start with click to
During whole test a stop is possible with activate
In order to run the test correct, following preferences have to be fulfilled:
Note:
No active error in ECU!
Engine speed is higher than 1500 rpm!
The used engine torque is more than 50% of the available torque!
If one of these three conditions is not met for more than 5 seconds,
the test is automatically aborted.
Step 2 – Trigger: temperatur prior oxi-catalyst >= 180°C
After step 1 is over, temerature is >180°C and all start conditions are met,a timer starts counting for 20 seconds (you can follow the timer, viewing the progress bar below the status window).
If the pressure of the SCR-pump will not reach more than 8,5 bar within the timer is running, the test will stop.

Step 3 – Trigger: temperatur prior oxi-catalyst >= 250°C
After step 2 is finished successfully and temperature is more than 250°C ,a timer starts counting for 5 minutes (you can follow the timer, viewing the progress bar below the status window)
Test will stop, if AdBlue injection mass ist still lower than 10mg or NOX-value (prior catalyst) is higher than 10ppm within 5 minutes testing time.
Step 4 –Trigger: AdBlue amount >10mg, NOX-value (prior CAT) > 10ppm
For 10sec. an averaging of NOX values prior and after oxidation catalyst takes place.
The decrease of NOX concentration is measured meanwhile by collecting the min- and max-values of NOX concentration.
If, while averaging process takes place, the concentration gradient > 50ppm/10sec, averaging will stop and start again (in order to guarantee a
stationary measuring point).
After 5 repetitions without reaching a stationary operating point,the test is stopped completely.
Test is successful if converting rate is higher than 30%.
The test result is shown in an overview screen :
The result can be saved in a Log-file:
