EBCM stores codes. My lights weren't on when I got my code with a TechII.

Wife ended up having to drop the car off at the repair shop. I think he and her had miscommunication on what to do. He thought she wanted him to diagnose it, and I just wanted the codes read. Anyhow, she woke me up this afternoon to go get the car with her. He didn't do anything with it all day, to busy. After I told him just the codes, we went out and scanned it quick. No ABS light on, so it stored the codes(which I post below). He didn't charge me a thing for the 15 minutes of his time we took, that was very nice, better than GM's cost. So it looks like I had a bad EBCM as well as an issue with the front right wheel. I'll have to strip the the plastic shielding of the wires and inspect for broken wires(hope it's that), otherwise I'll go and buy a new wheel bearing and put it on. I don't mind doing rear wheel bearings, but fronts can be a pain, and it's been a while since I did one. I'll update when I hopefully get a chance to work on it this weekend. I still have to finish building my fence gate so the puppy we got can't escape. Thanks for the help guys!

The codes are:

C0245 Wheel Speed Sensor Frequency Error
– The EBTCM cannot identify which speed sensor is faulty

C0040
Right Front Wheel Speed Circuit Malfunction
–
Probable Cause[s]
