Anti skid service required diagnostics - Vida read?

[JPLuch]

Hi there! New to the forum and to the Volvo life!

I got a 2007 3.2 petrol xc90 with an intermitennt warning for ”anti skid service required”. I did the yearly service and the mechanic did a scan to get to the bottom of it.

Attached the scan he made for me, not sure if it was done with a Vida thought... How can I tell?

For what I understand I need to change sensor B, I understand that is the one on the left right?

Am I reading this scan right? Can someone help me diagnose the issue?

Thanks in advance

I've very occasionally had the same DTC show for the brake pressure switch. It has never manifested any outward problems (my anti-skid is operational) and seems to be intermittent, as is yours.

Reading through your list, I think it's more likely the main problem is with your steering angle sensor and/or the SWM (Steering Wheel control Module). That's a fault which comes up fairly regularly on this forum. It's also intermittent in your case ("DTC not found active" shows that it wasn't logged during the last self-diagnostic cycle). Maybe just a bad/loose connection but it could also be the first indication of a pending failure.

I'd start with doing what was necessary to clear the multiple SWM / angle sensor faults and see where that takes you.

One thing to make sure, is to have a good alignment and the steering wheel perfectly centered when driving in a straight line. If the steering stays slightly off center, it may fool the YAW sensor into thinking the car is turning while it's actually going straight - it will throw a SAS error. Of course, there could be other things, but this one can affect the XC90

Looks like the standard fluff on the optical sensor fault. If you do have Vida you can read off the steering angle while you move the wheel and find out pretty quickly.

I would avoid working around a laundry list of fault codes.
Get them cleared, read the car again and see which come back as they will be the relevant ones.
Vida will then explain the reason for the code and the possible causes and fixes.
OP, if you want your own Vida set up, let me know.

From £100 delivered depending on your current laptop or £250 for a plug and play laptop and diagnostic tool.
Cheaper than paying others for code reads then sell it on when you get rid of the car.

Look like I will be doing a quick clean, make sure call contacts are good and if the problem persists might change the angle sensor.
Thanks again!

That is definitely a VIDA printout.
The format of the page layout is VIDA all the way.

Change the steering angle sensor (AKA clock spring).

Good luck.
