ABS/Traction control sensor failure

ab1

got in the car to go to work today and the Anti Skid System Service required came on with my wipers going skitzo and no functional indicators. turned the car off and on and got the wipers and indicators back.

driving home messaged went off and then came on and then went into limp mode with brake failure warning coming on . i applied the same technique and got that warning off and managed to get home.

from quick reading it looks like it may be the steering angle sensor thats the culprit but could it be something else (these seem pretty pricey)

Scanning with a Volvo dice using vida software is the fastest way to get a good answer on what's wrong

I've heard of this problem before. Probably just a bad battery or CEM issue.

If the battery is good, try cleaning the CEM connectors.

had a look at the ground terminal and it was caked in corrosion. will try cleaning that off to see if it helps. whats the CEM connectors?

The central electronics module is under the glovebox in RHD cars. See this https://www.youtube.com/watch?v=QkG_tGTdoYk

Cleaned the neg terminal was covered in corrosion and problem gone. Still will give the cem a clean. Thanks for the tips
