there should be more information other than 13 for the error code.
we need to know the node number it gives etc.
most of the codes i saw that have 13 all had to do with calibration but we need to know what needs calibration, the node number will determine this.
there is a big chance it is probably the accelerator but thats just a guess.
If you can get back to the truck and write down everything it shows when the error comes up that would be a huge help. ;o)
