Condition test of the variable turbocharger
This function is used to check if the nozzle ring can move freely.
The condition test should be run after the variable turbocharger electric motor has been replaced, or in cases of suspected malfunction of the turbocharger.
During the test, it is checked how much power it takes to run the nozzle ring in both directions between its end positions. It can be heard when the turbocharger moves between its end positions. It will seep out air when the test is run. This is normal and it is because of the resetting of the control unit and that the EGR valve and the bypass valve opens and closes.
The result are reported in the form of data lists where 1-10 shows how the current has changed when the nozzle ring has moved from fully open to fully closed position and the data lists 11-20 when the nozzle ring has returned to fully open position.
The values should be within the value 0-100. If the value exceeds the specified value, it indicates that the nozzle ring is stuck.
If you receive an error message about time out, you must turn off the function, turn the ignition off and on, then restart the function.
If the value 248 is shown for all positions, it means that the test has not been performed and that the turbo charger must be calibrated.
After completed test, the ignition must be turned off for the control unit to return to run position.
