If a reflash was indeed done when the CASE learn was performed then that erased all of the custom programming, correct.

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?

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...

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?
