Multiple Driver Assistance & ABS Faults

[Linus83]

Yesterday while driving home on the highway I received multiple faults related to driver assistance (lane assist, blind-spot, pre-collision etc.) and the ABS system and power steerin. Car was still drivable but at lower speeds I could tell power steering was out. It was late at night so I parked the car to check in the AM. They were still there in the morning but faults cleared as I drove on city streets but then they all returned when I was on the highway. I’m gonna take it in to the dealer this week but have had no issues until this in the 18 months of ownership.

You may want to send me your VIN so I can check what's up.

I had exactly the same thing happen to me on my three day old (new) 2022 GT. Had it towed to a dealership and they did a bunch of module updates and it's been fine since. But you've had yours a long time so hmmm.... Will be interesting to see what Lee finds.

BTW, I went back and looked at the notes from the dealer service when this was rectified:

Performed CMDTC self test with FDRS retrieved DTC'S B115E, B15E1, AND B15E2 from CMR module. Ran OASIS found SSM 50497 for concern. Cleared DTC'S, performed CMR on demand test, passed. Also retrieved DTC'S C0031, C0037 C003A, C0051 U0100, U0140, U0151, U023A U0293 from ABS module, U0401, U0415:27:2E: 2C from IPMA; U0415:85: 0A, U0415:00: 0A, U0415:00:08 from IPC. Cleared all CMDTC’S listed above. Performed on demand tests on ABS IMPA, IPC, all passed. Road tested and rechecked okay. Operating normally at this time.

Well what I see in the codes can be best described as "chaos", so that's probably going to be damaged wire or loose connection somewhere wreaking havoc with the modules and networks.

Read this and check if the positive jump terminal (red cap) feels loose when you wiggle it. https://www.macheforum.com/site/threads/car-bricked-while-driving-any-thoughts-on-this.16803/

You could also have a rodent that's gotten in and chewed a bunch of wires somewhere.

Good morning! If you'd like some assistance, please send over a DM with your VIN and Ford dealer info, and I can look into your concerns on my end.
