11. The "Secondary-air system" short test is running.

12. The "Secondary-air system" short test was carried out successfully. 

Once the short test has been carried out successfully, the short test will be blocked automatically because the diagnosis has been performed.

If the "Secondary-air system (total)" flag is the only flag that is not checked, this means that the short test has finished and the diagnosis was
performed. However, the cycle flag for "Oxygen sensor plausibility"  was not set or the "Basic mixture adaption" was not performed correctly.
