is there a website for checking codes?

[Summit]

i thought there a website to check codes? maybe it was a 2nd gen. only? does someone have a book? i have a code number but would like to find out what it really means,,, for sure.



2721?



thanks as usuall

Codes

Check the 3rd Gen. engine and drivetrain FAQ's

i'm blind?

don't see nothing there?? do I need to adjust my "eyes"?

 

[stick]

Sorry Summit, it's in the 3rd Gen. no Engine / Drivetrain FAQ's

thanks, don't see that code there thou. hmmm.



sure would like to know what this code means. anyone?

wonderin bout the 2721 code tho

 

[Summit]

i will call again today to make SURE it is 2721 and not 2127 as there is a code for that. he was pretty sure it's 2721 thou.







i know our trucks are built in mexico but i think it's an



"ancient chinese secret" code. :-laf



thanks muddy
