Hey guys please help been stuck for a week with this issue

[JimT]

do you have a batter shut off switch in this truck? sometimes when they go bad it can cause a similar issue. Otherwise, check all your fuses, check all your battery cabling like hookliftpete and rawze mentioned.

I personally had 2 different issues with battery cables on my pete that caused this same type of problem. One was a broken lug on one of the two (+) cables that run from my cut off switch at the batteries to the starter, it was arcing on the aluminum battery box when I would hit a bump. That one was pretty easy to spot and fix. The other was a cable that corroded away inside the lug crimp, underneath the insulation. All seemed just fine until I tugged on the cable and it pulled right out of the crimp with a cloud of disintegrated copper dust (that was an off-the-shelf Paccar branded cable).

Also, I've had this error pop up on occasion when the battery voltage has dropped too low when the batteries were excessively drained or when I tried starting the truck while I had a bad battery sucking the life out of the rest.
