Pulled my 9500lb RV 1000 miles on hvy tow last week. At the 900 mile mark I got a code. I had been pulling hills and pushing it pretty hard, but it was running perfectly. Concerned, I found a guy to read the code and reset it ($85
). It was a p1211 icp error. He said if it doesn't come on again, not to worry. Made it the last 100 miles with no trouble, and no codes. Been reading on here and p1211 sounds like a nag code. However, since I will be pulling my trailer back 1000 miles this week, I wanted to make sure I didn't need to worry about it. So, should this concern me?
Thanks!
