This test is used to check the NOx-sensors before and after the SCR catalytic converter.
Note:
NOx-sensors before and after the SCR catalytic converter warm up and become hot during the test.
If relevant error codes (9A0C03, 9A0C04, 9A0C0D, 900C03, 900C04, 900C0D) are detected during the test, then these must be resolved.
Test conditions:
Ignition on, engine off.
Vehicle stationary.
The CAN communication with NOx-sensors before and after SCR-catalytic converter is OK.
Procedure:
Începeţi funcţia.
A dialogue box shows the test conditions, check these and press "OK".
The test is run in three steps: Warm-up phase, function test, and cooling phase. During the test steps, data lists show that approved status is reached.
Check if relevant error codes have been generated. If an error code is generated, exit the function by pressing "OK". If no error code is shown, the function continues automatically.
The function is complete.
If the function fails, check the test conditions and repair
any faults.
