engine codes...
P1626 << this one i looked up in my Haynes manual and said... Serial data communication failure with vehicle theft deterent controller (no password)
my security light has come on a couple of times when i have been driving but goes away when i turn the truck off....
U1064<<< and this code i have never seen before. thought it was really unusual since it starts with a U
any help from any one would be great. thanks
