I've been trying to resolve this problem for quite a while now and would really appreciate any help you guys can offer. The problem started a few months ago. I had ran over a small icy patch in the road which activated the traction control (like normal), but the problem didnt actually show up until a few weeks later so I dont actually know if it is relevant. Anyway, The traction control warning has been coming on consistently for the past month or so. It usually starts after about 6 or 7 miles of driving but this can vary. I believe the code behind this is TC0073 which deals with communication to the EBTCM. Also if I clear this code while the traction control warning light is on then it will reappear instantly. Regardless if I clear the code or not it will usually be fine the next morning and the cycle starts over again. Other codes present are PC1644 (which is relevant but I don't think it is the culprit), IR1740, and IP1552 as of today. Again, I think the only code that really matters is the TC0073 since I can clear all codes except this one when the TCS warning light is on, but I could be wrong. Also today the car was going fine after a few miles of driving, so I stepped on the accelerator and then noticed that the TCS light had been activated. This is the only thing I can think of that could trigger it, but it could just be a coincidence. Sorry for the long post, but I would really like to figure out this problem so that I can get my first gear back all the time. Thank you for reading this post and thanks for any advice.
