Everytime i remote start i get a sevice 4wd messege on driver info center. It is an unltrastart remote starter. I used a PLDATA bypass, and a GMDLMULTI databus relay. The truck starts fine but gets the sevice message. I hooked up 2 ignition wires, 2-12 volt constant, 1 ACC, and 1 Starter wore just as directed. Any help would be appriacated. Thanks Josh

Check to see if you have a 2nd accessory wire that needs to be powered up. I had the same issue with a 2004 Aztec where the check engine light would come on when remote started. After I connected the wire, he didn't have anymore trouble.
