05 Freestyle intermittent AWD Malfunction
 

I recently purchased an 05 Freestyle SEL AWD that was showing the AWD Malfunction light. The seller replaced the rear sensor and control module and the light was off. It is now coming on intermittently. There is no rhyme or reason of when it comes on but I believe the AWD is still functioning when the light comes on. I have read a lot of posts about this issue but I did not find any information on an intermittent light.

Any ideas?
