low voltage

look at the wiring around your batteries. make sure none are corroded.

i drove a 95 kw that killed the truck for lov voltage to ecm code.

09 pete had the same problem. but didn't kill the truck.

 

Last time I had that, the alternator was going up, and finally did had to be towed for new one.

 

the batteries all check out good?

THE BATTERIES ARE NOT BRAND NEW THEY ARE 3 YEARS OLD I GOT THEM HOOKED UP TO A BATTERY CHARGER RIGHT NOW.

 

I would suspect the electrical disconnect switch of being bad. I have a 2000 Century and that switch and connections on it have caused most of my electrical problems.

 

Try replacing the ingintion swith, & get a schematic & trace the wires down to each componant and (OHM) test it, also test the fuse's, (both sides).
