I have a 2014 Traverse with 60,000 miles and registered for this forum today. I recently had a problem with my ABS, traction control, and stability control. I perused this forum and saw that a number of folks had a problem that was similar to mine. I wanted to share the details of how I solved it in case anyone else sees these problems presented in the same manner. I think there is a delay in new members being able to post things.
I look forward to learning here and passing on things that I learn outside of the forum.
I have a 2014 Traverse that the ABS, Traction Control, and Stability Control all lit up on the dashboard as not working. The most annoying issue related to this was that while the three items mentioned above were erroring out and appeared to be disabled, the all speed traction control appeared to continue to function which meant that when you hit about 30mph the engine would cut out and not allow the car to go much faster. By scanning with a OBD scanner that read ABS codes, I found that I had the following:
C0045-5A
C0245-00
C0110-00
The one error pertained to the wheel speed of the left rear wheel. According to the service manual the likely culprits for this error were the wheel speed sensor or the magnetic ring on the hub that the sensor reads. I decided to replace the wheel speed sensor first since it was easier and less expensive. For some reason this cleared the two errors that had nothing to do with the left rear wheel but the error that tied to that wheel remained. I replaced the hub and the remaining error code cleared.
Removing the hub assembly turned out to be a challenge. I tried pounding with a sledge, using a 10lb slide hammer and copious amounts of foul language with no success. I wound up buying Hub Buster pictured below and was able to remove it with three swings of a 3lb sledge hammer. I took the picture with the new hub in place as I did not think to take the picture before I removed the old hub. The tool is a little pricey ($120) but turned out to be a bargain as I don't know of any other option to remove the hub assembly.
Another item I found challenging was removing the wheel speed sensor. It is about a 1.75" long and inserts through the wheel knuckle. Amazingly, the plastic seized to the aluminum. I wound up snapping the top of it off and pushing the remaining part of the sensor out of the wheel knuckle with a drift pin.
Here are links to the scanner I bought to read the ABS codes and to the Hub Buster.
