Default C0047 and C0054 Error code

Hey everyone!

So I have a C0047 and C0054 error code in memory.

I've been reading up and apparently it would have something to do with the ABS Wheel Speed Sensor.

1) Has anyone ever had these codes pop up and how did you fix it?

2) Is there an ABS Wheel Speed Sensor for each wheel meaning that it becomes a guessing game of which is faulty or is there only one?

Thanks

What do the codes say specifically?? Any warning lights displayed on the cluster? How does the car run? Miles? Mods? Any work done recently on the car?? We need more info. We are not mind readers and we cant help diag anything like this online without more information.

Yes each wheel has its own wheel speed spensor.

Car is stock except for Cobb Accessport but issue occured before Accessport install so I know it's not that.

There are no warning lights on the dash only the C. Diff Lock will start blinking.

Car runs as it should, I can still change between all there drive modes (Intelligent, Sport and Sport#) and I can deactivate the stability control no problem. The only thing I can no longer do when the error occurs is choose my DCCD setting.

The problem is completely sporadic, but at first I though it was when it was too cold but this morning it was cold and it didn't pop up.

Is it possible for snow or slush to mess with the sensors or causing a short in them? It's the only idea I can come up with but it would be stupid if that was the case seeing as the car is made for winter IMO.

What did the codes say specifically? Were they specific to a certain wheel speed sensor? You can also inspect all of them to see if there is any visible damage to them and the wiring.

Unfortunately I don't have any other info to go on at the moment. I will try to adjust the brake light switch and see what happens.

Do certain fluids or oils affect the DCCD?

Next step is to inspect the sensors to see if any were affected due to snow. My only problem is I'm not set up to be able to remove and replace wheels easily making the task a lil more difficult.
