I could pull out and inspect the front wheel sensors easy enough and was hoping I could see the signals with a DIS/INPA system, I don't mind investing the 35.00 and time to have a fully capable diagnostic machine available, and have in fact order that cable. I'd just like to fix it sooner as the snow here is becoming unbearable. (Also could used the DIS/INPA for my E39) The truck is garaged nightly, but not in a heated garage (I wish!).
