X15 Rear Bank Injector Short Circuit

[Hermjeji]

On the X15 we have, following FC's came up: Fault Codes 323, 325, 332.

Engine is still under warranty, was close to a Kenworth dealer and they're looking into it. My hunch is something to do with the harness if all 3 came up at once. The wiring diagram shows the injectors going to the ECM directly, would there be a difference with reference to the rear bank vs front bank? Looking at QSOL, i don't see where the rear bank of injectors would be combined vs the front bank.

Anything I should look out for, I'm well aware of the fears of having this done at a St**lerSH*t.

Symptoms were derate code came up and engine started running really rough. Drove it about 5 minutes from when it came up from when I dropped it at the dealer.
