Rear height sensors for ABL - which side?

warninglight · Dec 14th, 2018, 12:27

Hi all,

My 2012 XC70 SE LUX has started having problems with the self levelling on the headlamps, causing the occasional message on the dash and dropping the beams.

VIDA gives code CEM-B104421 Rear Axle Sensor, General Signal Failures, Signal Too Low

I believe it has a sensor on each side - but nowhere on VIDA does it specify which side this is - does anyone know?

VIDA also mentions if this code comes with B104321 then it's likely to be a feed issue, as that number relates to the other sensor. But it still doesn't tell me which is which!

Any help would be appreciated before I crawl under it!

Thanks
Stephen

My car has one sensor on the front axle, one at the rear. Both are on the right side. You'll see the lever when you look behind the wheel.
