I've had JB4 in for a couple weeks and a "Service Engine Soon" light came on today with the following codes (I tried searching with limited success):

2AAF (fuel pump related) -- normal tuner code?

2A13 DTML (fuel leakage related) -- I was driving around on empty for a little bit today. Could that have caused it?

2A2D (fuel pump related) -- normal tuner code?

I am on Map 1, DCI and 93 Oct.

Thanks!

DTML is a common code. Check gas cap, delete, and dealer if it comes back. 2A2D means your low system pressure is too low.

Thanks - so how do I correct the low system pressure?

Put some fuel in it and see if it comes back. If it does dealer it.

So after checking gas cap, deleting and going to Map 0, the following code returned:

2A13 DMTL diagnosis module tank leakage, leakage diagnosis pump, input signal

Before I dealer it, can someone please confirm that there is little chance it is JB4 install/connection related? I'm out of warranty, so I'm not inclined to take out the JB4 before taking it in and want to make sure I didn't plug something in wrong.

Since it ran fine for two weeks prior to the problem, it does not sound like an install/tune problem.

I had that same DMTL code..
Dealer it.
It`s some type of pump that regulates the conditions (seal/vacum) of the fuel tank.
They replace it.

Thanks. Dealer tomorrow. I'm out of warranty so hopefully it isn't too painful.
