I have a 2006Jeep Grand Cherokee, the light came on Service 4WD? How do I reset this message?

The computer has detected a problem and set a code. You will have to have it checked with a scan tool.

ADDITIONAL INFO: This is a known problem with newer model Jeeps. It MIGHT mean this is an issue or it may not. I have had this problem with my 2006 WK (Commander) 5.7L and my 4WD still functioned properly.

Unfortunately your only viable option is to take it to a 5 STAR Dealer and have it diagnosed, since this is a specialized system and most independent shops do not have the StarSCAN tool to service it. Chrysler DOES know about this problem and issued a Technical Service Bulletin on the subject.

Please keep in mind that while Chrysler DOES know there is a problem, they are not required to fix it at no charge if it is not within a warranty period. This particular problem is NOT a recall.
