DTC question

[Butcher]

I just installed the V10 tune in my car (2013 SHO) and discovered I had a DTC. The code was B1215. When I checked the code's meaning, it says "B1215 Running Board Lamp Circuit Short to Battery". Does anyone know what this means or what might cause it? This seems like a code for a pick up truck or a van. Cars don't usually have running boards.

Interesting. Have you converted any of your lights to LEDs?

All kinds of weird codes get set when loading a tune. I'd reset codes using the tuner and see if it comes back.

I have had P1000 before but I always just clear it and move on. I seem to recall someone else having that 1215 code and thinking it might be due to the LEDs that they had added. If it doesn't cause a MIL, I wouldn't be concerned about it.

The code was there before I installed the V10 tune and I had to clear it to install the new tune. I haven't touched any of the lights, and haven't seen any problems with any of the lights. I'll check in a week or two and see if any codes show up.

P1000 means that the ECM lost power. That is always going to be a residual code from accessing the OBDii port. As for the other types of codes, there are B and U codes that your car even stock will produce. That is totally normal! There are billions of packets of information that are sent to and from your ECM during the course of even a short drive. There will always be several instances where there are packets of data lost. The ECM will log and record this miscommunication and store (usually) a U coded DTC. That doesn't mean that there is an issue at all. It is just a log of an error that occurred. B coded DTC's can range from a random bump that caused a fuse to come loose for a split second to your airbags having a malfunction.

Here is a list of the types of codes that exist:
Powertrain ("P") codes
Body ("B") codes
Chassis ("C") codes
Network Communications ("U") codes
