06 Jeep Grand Cherokee lights tripping ou

I got it here and the only code I pulled was a parking lite low. and the unit has been working fine for the past few days. I talked to the dealer and of course he cleared all the previouse codes, but said there was a ton of these loss of communication codes over 15 key cycles . I guess that could have been from programing , but who knows. I'm goin to clip the park lite wire and recheck all the bypass connections. anyone else have any advice?Tire Proz Stillwater Mn
