Just read and clear the faults. Then go for a drive and then run another test after to see what remains.

The B codes are ok but I have limited access to some of them.

Hi, first time in the forum, was going through the topics this one looks the closest to my issues after using Diagbox 9.68 B1220 62 code comes out which is automatic cruise control fault, has anybody had this issue and has been able to sort it?

Can't help you with this code - but if still in warranty, get to Citroen. It may be a calibration issue, as if you have the cruise control with automatic distance keeping, then the C5 Aircross has an ARTIV electronic control unit built into the front bumper somewhere near and below the number plate. These can be notoriously sensitive and if they are the slightest bit out of alignment, it can cause the function to stop working with a fault.

It would need investigating by Citroen as it may require checking and recalibrating.

Thank you for you reply, unfortunately the car had light collision which I assume contributing to the issue because of that I think I am not covered by warranty anymore but the impact was very light anyway and the radar itself was not damaged.
There is another fault U1162 87 Vehicle Distance Assistance (cAN) would you say there are related?
And do you think it is possible to fix without going to dealer ( I have access to Diagbox).
