2013 F150 Ecoboost 2wd Supercab

Been having some issues with the transmission so I pulled the pan, flushed the system (fluid was dark and had some metallic contamination). I pulled the valve body (they refer to it as the main control) assembly out. I disassembled it, inspected everything, meticulously cleaned it, replaced all of the clips and the end pistons, reassembled with new mid-plate and reinstalled into the truck following the EXACT dealer procedure in my purchased dealer FSM/repair manual, torque specs and torque sequence, etc. This all started when the orange light flashed and the truck started shaking violently like it was shuttering the TCC at a high frequency. When I cycled the key, the orange wrench light was no longer there and it would drive again but started having the TCC slipping issues and erratic shifting, flare ups, locking the TCC too much on decel and almost stalling, etc.

The symptoms are still there. The symptoms have changed slightly but still are mostly the same. It doesn't really know when to shift, is very inconsistent and seems to be hunting and slipping the TCC inappropriately. I do not have a Ford IDS to clear adaptive trans tables (it is non-violatile RAM and pulling battery cable does not accomplish this) but I have a higher level scanning device that can pull a lot of codes beyond the PCM codes. I pulled the following codes today:

U0151
U0140
U0452
U0131
U0100
U0114
U0155

All of which have to do with lost communication with various modules. Has anyone else experienced these symptoms and or codes? I am not receiving and TCM codes with my scanner so I am at a loss right now. There is a Ford representative on here right? Could a full re-flash of the powertrain modules and drive cycle relearn resolve this? Anyone?

Looking at the 2013 Ford shop manual the only codes you posted that are valid are:

U0140 - Lost Communication With Body Control Module
and U0155 - Lost Communication With Instrument Panel Cluster Control Module

The pinpoint test is the same for both of those codes and very technically detailed.

Note: If the self-test or communication concern occurred after a failed or an aborted reprogram, the module may be blank. Attempt to reprogram the module again before continuing with this pinpoint test.

Visually inspect the following for obvious signs of electrical damage:

harness wiring
electrical connections

Verify the correct procedure was used to activate the self-test for the scan tool.

The Ford reps that were here are no help, probably why they left.

EDIT: The scan tool in question is IDS and without it testing is nearly impossible, there is another you can try and it's practically free, it's called Forscan, here's a link to get you started on that road, just takes a windows Laptop or tablet and a $30 usb obd2 dongle. https://www.f150forum.com/f38/forsca...ations-349018/

Thank you much for taking the time to respond! So I am going through my 2013 F150 dealer repair manual I purchased from "MITCHELL 1 DIY". It is extremely detailed. This is the following info I found:

U0100 - Go to PINPOINT TEST K
U0114 - Go to PINPOINT TEST L
U0131 - Go to PINPOINT TEST M
U0140 - Go to PINPOINT TEST O
U0151 - Go to PINPOINT TEST P
U0155 - Go to PINPOINT TEST O
U0452 - Go to PINPOINT TEST P

and another location says:

U0140 and U0155 - Got to PINPOINT TEST QA

The OBDII dongle that I have and am using is this one:


Will this one support Forscan? Thanks for the feedback!

Also, I am not sure I understand exactly the process to accomplish what you mention here:

1. Attempt to reprogram the module again before continuing with this pinpoint test.

--> I have used both SCT with purchased tunes as well as my own tunes (I run a side business tuning LS based platforms, and just started on newer Ford vehicles) using HPTuners. I have a feeling this may be the issue and something with the cross compatibility. My issues started shortly after using both. What do you suggest doing to get it completely cleaned out and back to the original backbone? Programming the factory calibration back to the ECM with SCT and HPTuners did not resolve this. Something must have been corrupted. Any help here is appreciated.

2. Verify the correct procedure was used to activate the self-test for the scan tool.

--> I assume this is different than just pulling the codes? It has Mode 6 in it and I believe it can run some self tests. I will have to investigate what the "correct procedure" is.

Thank you for this help. I am a seasoned mechanic and performance tuner and have never paid a dealer to resolve something for me. I would like to solve this myself, however this newer Ford programming/compatibility stuff has been quite the PITA, and I do not have the authority to access it with my scanning tools.

The pinpoint tests I have available are from the Ford shop manual, same manual dealer techs use and require IDS. I wouldn't put much trust into the Mitchell manual.

This is the interface device I use with Forscan and my laptop you can use Forscan to reprogram all the modules in your truck with asbuilt data you can download from Ford should the module(s) be fubar.

Link for asbuilt https://www.motorcraftservice.com/asbuilt just enter your vin#

Sorry I can't be any more detailed as you do not have the required diagnostic hardware/software for the pinpoint tests that I and Ford dealer techs would use.

Great thanks for the link. I was looking at this one on amazon:


Would that one get me any further than the one you linked? FYI I dont really care about wireless or not. But I see that the one I posted has GM advanced support which could be beneficial for other vehicles I work on.

So if I download the asbuilt data, I could reprogram all of the modules back to off the floor and the trans adapt tables would then be cleared and allow me to relearn? I was thinking Forscan was almost equivalent to IDS, but now I am confused. Is forscan with supported OBD2 dongle basically a limited version of the IDS?

The one you linked is just a basic code reader and it cannot access all modules, you could use it as a pass thru but I don't like to have programming out in the air, having the usb cable is also faster as well, your truck has two networks HS-CAN and MS-CAN, the switch on the one I posted allows you to access both, you need IDS or Forscan to do any programming, Forscan as a matter of fact can do some things IDS can't, I also have IDS. I was able to make my fog lights day time running lights as an example, activate remote start, program keys etc..etc 2011^.

IDS you can only select front turn lamps or headlamps as DTRL. Yes you can flash every module in your truck to the state they were in when the truck first rolled off the factory line using asbuilt and Forcan.

EDIT: Forgot the link to the Forscan thread for your year model, here ya go and happy programming, modifying, https://www.f150forum.com/f38/forsca...ations-349018/

You are THE MAN! Thanks so much for taking the time to provide this information.

I ran across another thread claiming that the one I linked does as much as the one you linked. I also like the idea of hardwiring for the programming. I will go ahead and order the one you linked. Thanks for the help! Now to just get Forscan on my computer and get it to communicate with the device when it shows up!

Do you just switch the side of the device to MS-CAN when programming? Curious why the manual switching exists rather than some sort of auto feature?

RoastinF150

Last question:

Can Forscan access adaptive trans tables and clear them? Thank you!

RLXXI

Forscan will ask if you have a switch, you select yes and it will prompt you to flip it, just that simple. Strongly suggest you take a few days or however long you need to go over that thread 1st post to last, there are some to skim over but you won't know it until you read it LOL. it's a long read but oh so worth it.

Not sure on the why for manual switch, just the nature of the beast that is Forscan I guess.
