My driver information center unit in my car isn't working properly. It was working before and told me my average fuel economy, range, oil life and fuel used. Now only the fuel used and oil life are working. I disconnected it, blew strongly into the coord and re-connected it making sure it was nice and snug and as I was pulling out of my driveway after that it went from 0.0 MPG to 0.1 MPG but then I drove further and it went back to 0.0 MPG. I changed it to range mode and it said 3 miles and was stuck on this, it did not change as I drove for a while. I held the reset button and have tried a few other things but nothing is really working. The ABS wire did come loose on my car and I reconnected it but there might have been some gunk in there, could this be the problem?
