That is communication has been lost see pic for explanation. A pro has to hook his scanner up to see where the problem lies.

Thanks, I spoke to the shop Forman at my local dealer and he said that there's a ground wire that is most likely not making a good connection and to clean all of the ones that I can see under the hood. I totally forgot to ask him which one's are most common on my pickup. Has anyone else found out which one/ones cause this because it's a common problem with the older Nissan Titan's

Nope I would do body to battery, engine to battery at least.

I have always been a fan of adding additional grounds to my vehicles especially on this pick up because I have a winch and power inverter hardwired and I have two grounds from the battery to the body, one ground from the battery to the frame and one ground from the battery to the engine. And have had those on there for a few years now thank you for your replies I need all the help I can get.

That shouldn't make a difference you have broken or shorted wire someplace.

Ok I'm going to have to go to a buddies shop and see if his scan tool is capable of testing my CAN system, I'll post my findings.
