Recently i have had battery issues with low voltage. Truck wouldn't start, followed by lots of clicking. Charged batteries, truck starts as normal. Smarty jr. came up with a cel/dtc of 0513...invalid skin key.. What does that mean and is it related to bad batteries???

Thank you....your reference was right on. It describes exactly what i have been expriencing.

 

Anytime! I recently went through a number of goofy issues, and they seem to have all been caused by a bad passenger side battery.
Good Luck!
