The PCM is in and no new codes.
Vehicle still doesn't raise in sand mode. It did the first 2 times on the beach and the owners manual says it should. The tech even printed the page from the owner's manual so I know he looked at it. The response from the Jeep engineer was that it is not supposed to raise in sand mode.
I asked them to do the uConnect update. They told me there were none showing up, and the tech said that the systems usually update automatically. I'm downloading it now, but they must have no bandwidth on that site. It is taking forever.
