Hey guys I,ve come across this check sum error code sometimes when checking my truck for codes and Im wondering if some of you can tell me what this the truck runs fine so I dont think its anything major just wanting to know what yall think.

 

p602 I believe....I thought it was from when you have a programmer installed sometimes it brings this code up..Smarty used to have that code show up but Marco fixed it for the Smarty guys.....

 

you should get you a smarty to clear them out

 

Thats it then I had smarty on my truck and I would see I every now and then when I was checking for codes thanks for the input guys.
