    Never saw any code but stored messengers said to service air bags and another was parksense not available service required. I’ve seen the air bag one before but it goes away. The parksense I haven’t seen before but think it would also disappear if the truck fires up. The engine light comes on and off. Can Batteries cause this much weird stuff even-though the engine cranks fast and strong?

    Yes, low batteries will cause the truck to have a mind of its own.

    Load test them

    That's good to hear!

    Low Voltage strikes again.

    Might want to check the alternator.

    Don't want to run the new batteries down if there is a problem with it.

    So much for new batteries solving the problem.

    Ran great for a week or so and this morning it did it again. No power to fuel pump, sunroof, rear windows, back slider, and probably some other things I haven’t discovered yet.

    This has to have happened to somebody before.... I still think it’s a module or maybe a loose wire to something that controls all those other things.

    Disconnecting battery’s and touching cables to drain computer seems to fix for a while (I try when I get home tonight) but am still at a loss for the exact issue.... very frustrating!

    Anybody have any idea what is going on???

    This is a long shot BUT:

    Check your main wiring harness where it comes through the fire wall on the engine side. My harness was rubbing on a bolt that goes to the ABS controller. It actually rubbed through a few of the wires and caused the truck to act much like you are describing but I had a "NO BUS" message on the dash.

    Just make sure that harness (about 100 wires) isn't rubbing anything. Took me almost 8 months to find that.


    My guess is something is shorting some place.
