Read this thread, everything you wanted to know about a case learn is described in detail by Rogue.

Prgramming was not removed.....fans still run after engine shutdown and car seems more repsonsive then with the stock PCM. I like the way the car runs with the Intense PCM....I don't want to take it out. Theres' just a few little things I'm curious about.
So can any of you very the fan turn on point for me? I'm watching my scan gauge and assume the fan is coming on when the coolant temp starts to drop....maybe that'* not the correct way? Is there a better way to determine actual fan turn on temperature?
There are 2 speeds for the fans, by default we command low at 185 and high at 195 for a 180T-stat setup. Have you tried running the auto climate system and looking at the fans? Auto climate should kick the fans on to low. Have you had someone in the car watching the temp on your scan gauge while you looked at the fans to see when they kick on and off?

So basically, I should have a case learn done?

I can try that.....just fyi, I pulled in the garage and sat there for a second. The coolant temp went up to 224 and then the fans kicked on and the temp started to drop.

Forgot to mention I put the FWI back on....same IAT'* and up to 6 degrees of KR...I'm gonna let it learn for a while before I draw any conclusions though...

If it wasn't clear in the other thread the answer is yes.

Just as I thought. I wish I would have know about this when I was at the dealer last month. Now I have to find the time to do it, and a dealer who is willing to do it.

Ok....I checked the fans and when I put on the climate control they do come on. I think on low. Then when I turn the climate control off, the fans turn off.....even though the temp is well over 200 degrees. Then they stay off until around 224 and come on.

Any ideas on how to troubleshoot this? What controls the fans? Could I have a bad relay? If I lost high speed fans, how do I figure that out? If that is the problem, why does low speed fans not come on? Maybe I lost low speed fan? The speed the fans run when climate control is on, appears to be the same speed as when they run during the "2 minute fan after turning engine off" I-PCM feature. SO I'm not sure if that'* low or high. What'* the best way to find out what speed they're running?

Email me your Name and Order number and I'll look into the code more closely.
