Purchased a lifted 2020 f-150 less than 20k miles and wasn't having any problems with it. Recently started showing multiple warning lights on the dash along with multiple warnings (service adv.trac, front camera malfunction, park brake malfunction, pre collision assist unavailable). Steering will become difficult but then all the lights and warnings go away and leave just the check engine light. I have taken it to the Ford dealership and they have had it for 3 weeks and have no idea what it is.

 

So, I have spent hours reading through old threads and figured there are three main issues to try and address.
1. loose pitman arm bolt
2. dirty/corroded electrical plug near the spare tire area
3. E brake latch or the connector is loose and needs to be unplugged and replugged.
Ford is replacing the ABS module or something but is waiting on the part. Once they do that I am going to pick it up and try these other fixes myself. Tired of dealing with them.

 

Multiple warnings are often times indicative of a bad battery.
The Dealership should be aware of that.....

I would check the main ground.
I bet your losing ground.
Probably something was loosened or not grounded properly when the lift was installed.
Loss of steering is a bad thing.
If you don't know, the truck has electric power steering.

 

Yeah, I've also heard about the battery but it was tested and is good. Ford said they went through and checked all of the electrical wiring and ground and did not find anything. Once I get the truck back though I am going to check it all again and see for myself.

 

When multiple systems are shown, One fault source that is used by other systems are included in the dash display because they cannot fully function.
A full diagnostic print out is needed to see them all and see which one is the source and >>indicates a code #.
All the other parts of the system can be diagnosed separately and should test OK.
The fix it the one with the code set.
Good luck.

 

 

It won't be a pitman arm bolt since these have rack & pinion. (EPAS at that)

 

I have a 2017 F-150 XLT 4x4 V8 with 28k miles. We went to Oregon in October and hit some heavy rain while it was being flat towed behind a motorhome. When we unhitched and were driving to a wedding was the first time I got error messages about Advance Trac, Check 4x4, Hill Assist, ABS, etc. The messages would go away with the OK button. Go forward a few weeks and more error messages started coming up.

I went to O’Reilley’s and the scanner showed some Codes: P062C-00; U0121-00: U0212-00; U1012-00. The turn signals, cruise control, radio controls, intermittent wipers (top speed still worked) and most everything on the steering wheel controls stopped working. A mechanic scanned it and indicated a bad SCCM (clockspring) which was replaced. Most error messages still there. He tried to scan again and no communications with any module except the SCCM. For a few minutes all seemed OK. Then the Steering Assist Fault message and the steering seems to partially work, gauges and dash lights went black. After 20 minutes I restarted it and the gauges and lights worked again. I replaced the battery.

I researched and found out how to enter Engineering Test Mode. The current Continuous DTCs are: C40182; C12100; C41582; C42082; C15100; C21200; C42982; C10200. I can’t find anything about what these codes indicate. I suspect that the C codes may be related to the ABS system, and it might be at one or two locations in the system since all of the codes end in 00 or 82.

Any help would be appreciated. I would like to avoid the local Ford dealer here as they are not trustworthy and known to be less than honest.

I had it all type up to send, then a Tel call came in on my cell phone to go on the air.
When I got back to it, it no their!.
So here is a short version of it.
The codes have to be converted to the U code format. Thats why you did not find anything about them.
For example, the first code c 40182 is re-stated as U 0402:82.
All the codes are saying lost or invalid data.
What these codes are for is internal talking between Module on the Bus networks. That would mean many locations.
If you go to the Ford DTC U Code list, all will be there in that form and tell the same description and cause between the various modules.
I did all the conversions and looked then up to be sure.
If you test each MODULE with Forscan and they pass, the codes should clear unless there is a fault at some common location.
Good luck.

 

Thanks for the info.
The mechanic tried to scan the modules and can't communicate with any except the clockspring (SCCM?) which was just replaced. I think that he was using Forscan.
After I removed the connector at the ABS controller and cleaned it with electronic contact cleaner, the dash error messages haven't returned. The only issue that I can determine now is the power steering isn't working correctly. It has partial assist when rolling and RPMs are increased from idle. I'm almost to the point where I'm considering going to the local dealer. The next closest one is 50 miles away so options are limited.
