I have a 2005 dodge 2500 turbo deisel. I have installed a Banks Six Gun computer system. The Six Gun has been installed for about a year and seems to be operating well. I now have a MIL light. I am worried that if I take it to the dealer for service they will not honor the warranty. Is this a problem? Also do you know what a "C" code is? Any help will be appreciated. Thanks in advance, JTM.

 

Take it to Autozone, Checker whatever local parts store and have them read the code and find out what it is.
