Tried searching, but for some reason (probably my own) I couldn't come up with anything on how to clear the codes on a 4th gen truck. Do I just disconnect the 2 ground cables for 5 minutes trick?
I am getting a P2609 Generic code (Intake Air Heater System Performance). After a little research on the code, I am going to check & clean all connections & would like to see if it still throws the same code.

 

Not really sure if disconnecting the battery cables will help, I know that if you take to Autozone or Advanced Auto and they run the scan tool, they will not clear the codes for you however, when I asked about it a while ago, they said "Here, see this button, press it and it will clear the codes" all while they looked away.

 

What I Did for my Dakota was, run the code reader to clear the the check engine light. Then disconnected the battery for maybe a 1 min then hooked it back up. Should work for your truck.

 

That DTC is probably erroneous. There was a STAR case where it stated they were developing a software update for overly sensitive diagnostics. It was not dated, so you may want to check with the dealer and see if there is a flash available on the scan tool.


TSB 18-005-13 was the latest mentioned for the flash.




I'm going to move your thread to the Diesel truck section, as that is a Cummins DTC and I assume you have a 2500 ?


Belated Welcome to Dodge Forum, BTW

 

Thanks for the information....and yes, it is a CTD 3500.

 

disconnecting battery cables isn't going to clear any codes. This isn't the 80's or early 90's lol. ECM's these days store everything to non-volatile memory. kinda like your computer saves things on its hard drive...it isn't going to lose that memory when you take power away...
