Test of compression brake

This function is a test and is used to check the vehicle compression brake. The test is performed during two different sequences in which the fall time of the engine speed is measured. The first sequence is performed without activating the compression brake while the second sequence is performed by activating the compression brake. The engine speed is increased to a defined value, after which the fuel supply is cut off and the fall time to idle speed is measured.
