Hey all,
A whole lot of searching the googles and forums and no one seems to have reported this DTC before, so figured Id reach out to see if anyone can help.

Over the past week, sometimes when turning the wheel to full lock (backing out of driveway, mostly), I get a momentary alert message on the dash that immediately disappears, too fast to actually read it. No dash light occurs.
So, I plugged in ForSCAN and am looking at this DTC in the PSCM: U3009:1B-2E. I cant see the actual message at the moment, but it includes some statement about some circuit resistance being too high.
Additionally, when I try to run the PSCM On Demand Self-Test, it immediately fails. Ive cleared the code but it just comes back the next time I drive the truck.

Anyone have any ideas, or even and suggestions on what to check? Im at a total loss here. Thanks!

Based on the base fault code (U3009) it looks like you have a problem with a control module ground or possibly a bad module.

Thanks for the info! Is that from a publicly accessible source?
I guess the best approach at this point is to start at the steering rack and just inspect the whole wiring harness run?
Have a feeling if I took it into the dealership they’d just tell me they need to replace the whole rack. ?

Did Forscan give you a better description?
