Temporary shut off of engine after-running

This function is used to turn off the engine after-running. The engine after-running is turned off only once when this function is started.
Engine after-running means that the engine, after the ignition (terminal 15) is turned off, continues to run for about 2 seconds to burn the residual gas contained in the lines (to protect the catalyst).
By interrupting the engine after-running once with the "Diagnostic tool", you can check all the inlet valves.
Note:
This function should be performed with engine at idle!
After the ignition is turned off, this function is deactivated.
