The place to start was the beginning and end. I pulled the positive cables off both batteries and under each clamp was some white powder corrosion. Cleaned it all off with a battery post brush and cleaned the clamps with the same brush. Sprayed both batteries with Battery acid neutrilizer then washed it all down witha little clean water. Wiped it all down and reattached the clamps after 20 -30 minutes. Sprayed each post and clamp with some Rem-Oil. The CEL is no longer shining and after three trips is still off.

Thats why it is good to know you smart people. Dealership would have gotten at least an hour of shop time and probably would have started changing parts instead of checking the simple thinks first. It was the simplest and cheapest thing that caused the problem.

What can I do to the batteries to keep that from happening again? Use to put a little motor oil on the post growing up but it was nasty. Thats why I put a little Rem-Oil. What about those little green and red wool looking things that you can put on each post? Do they help?

Thanks Again Guys!!!!!!!!!! ;tu

That Scale (powder) is common to most any battery connection.. in time. These PSD ECM/PCM's are REAL sensitive to strong, clean 12v current and Amps. Manya Gremlin has been fixed by a Good post/clamp cleaning, and Load Test. Glad it worked for ya ;tu

Everything you did is about all you can do, but..... Routine battery maintenance seems to work fer me. At each oil change I give my batts a good inspection, and at [least] twice a year (Fall & Spring).. the post, cables and clamps get a REAL good cleaning...

Sounds like I'll be going to get the little wool doughnuts for the batteries. I dont need to let the gremlins have any point to attack the truck.
