Strange errors related to abs+ airbags and more when i start the cabin fan.

Post by AdrianS »

Hi,
My car is a Citroen C4 2005 1.6HDi 90hp.
So last week i encountered some very weird situation. Randomly while driving, I got the following errors:
ABS System Faulty
Braking System faulty
A-BAG/S-Belts faulty
No speedo was shown anymore , just ___ lines
No power steering was available
And the fan stopped working.
After I turned off the engine, it did not start. I had to wait a bit for it to start.

After the issue came back again the second time, I noticed that this happens only, but only, when I turn on the cabin fan . Starting the AC caused the errors to pop up faster, but today I noticed that as soon as I start the fan the errors pop up.

I tried to check the fuses but nothings seems blown and I went to a friend to check the errors code and in the attached image are the errors that I got on the BSI.
Does someone have any clue what may cause this? Some grounds or ?
