Both wheel speed sensors defective?

hapklaar · 07-07-2020, 01:04 PM

My dashboard started looking like a Christmas tree, with ABS, DSC and Airbag lights coming on.

Did some digging with INPA and found the following faults:

5DC3 5DC3 - Drehzahlfuehler hinten rechts Anfahrerkennung v_Vergleich.
5DA3 5DA3 - Drehzahlfuehler vorne rechts Anfahrerkennung v_Vergleich.

93FB SBR-Funktion - Geschwindigkeitssignal fehlt

They all seem to be related to wheel speed sensors. What seems strange to me is that both sensors on the right side have failed at the same time.

Is this normal, or might it point to a central connection error or something similar?

Maybe both right sensors share a single plug to some module?

Did you ever figure this out ? I just had the same problem with both front sensors throwing codes and I replaced the right front just a few months ago.

You can test this in INPA by looking at the live data of the wheel speed sensor. All you do it plug it in and turn the car on. If the sensor shows the car moving while you are sitting still its messed up. You can also take the car for a drive while INPA is plugged in and make sure you are getting consistent data from the sensors.

I was just dealing with similar issue with 5dc3. I removed the abs sensors in the back and cleaned reluctor rings and abs sensors as much as I can with scotch brite wd40 and brake cleaner. Put them back and drove around a bit and seem to have solved the problem. The traction control is not coming on and haven't seen a code come up yet.
