Filled up my rig up $93.25 and the turned the key on and reset my trip log and all my lights on the cluster came on and a "C-Code" light came on! There were not any numbers that I was able to see. Has any body had this proble or can u tell me what I need to do. I have about 43k on my rig!

 

I think you accidentally activated an Instrument Cluster diagnostic test, which will show any instrument cluster errors if any exist. I don't remember the exact sequence to do the cluster diagnostic test, but it does sound like that is what you did. Kind of like the key off/on sequence to read DTCs.

 

Yep, that's the instrument cluster self test and it's performed by holding down the trip odometer and then turning the ignition switch to ON.

 

Thanks for the info I really thought I was going to have my first major problem.
