So scanned my 06 gxp today because I keep getting a service vehicle soon warning in the message center.I pulled a U0073 control module communication bus off code.I did a search and am not having much luck.From what I'm seeing its communication issue between tranny and engine.I also pulled C0240 pcm traction control not allowed.If any one has any knowledge in where to go from here,or experience with these codes please let me know.Hoping it's nothing to serious.
