YES
The measurement value is OK.Note
- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose
contact and corrosion..
End of test
NO
The measurement value is not OK.Possible cause and remedy
- Lines to component N51 (AIRmatic with ADS control module)
- N10/1f45 (Fuse 45)
End of test
