That function may not be available or does not exist.
Resetting any control module does not and never will eliminate any current and recorded errors.
You need to go back to the scene of the crime.
Open your owners manual and if you don't have one:
https://www.fordservicecontent.com/Ford ... 3_2016.pdf

If the .pdf is saved, use the combination keys Ctrl+F to type in the search such as Fuse.
You have two fuse panels. The main one in the engine bay has two sections - Do Not Break It!
The other is in the passenger compartment.

The entire network is not happy because it didn't get it's regular and daily infusion of poutine.
The poutine has been disconnected. :D
Fix the poutine problem, then you can get to move forward.

U019E:00-6C
The TRCM could not communicate on the network at a point in time but is working.
Vehicle may be stuck in current range. No Forward or No Reverse.
The Electronic Parking Brake should be applied if park is selected.
CLEAR the DTC. REPEAT the network test. If DTC U019E returns,
REFER to: External Controls (307-05A) .

Read the schematics and use a digital mutimeter for testing.
One last time - Post the image when the vehicle is connected with the Modules Tab in view.
More on this after I get my own poutine.

so When i reset The DTC is u019e does away, it comes back after i start the car.

picture after reset
then picture after the car was on for 2 minutes

I Have a 2nd Fuse box ( the one that is in the engine bay (2 part one) i replaced it with a spare and no effect. so i know all fuses are good at the fuse box. (engine bay fuse box) i checked every fuse with a multimeter also and confirmed its good.
I checked the fuses on the inside of the car and everyone was good. Fuse 16 on the BCM is for data link. confirmed its good too.

my shifter works fine. i can drive the car with no issues, it goes from reverse to forward and park fine. it shifts gears good too.

You have network faults and seem to have difficulty is responding to simple requests:
All of these are network faults and now you've replaced a fuse panel with a spare.
APIM - U0155:00-0B
BdyCM - Error
GSM - U1011:00-AE
IPC - U019E:00-48
IPC - U0212:00-48

What is in that car that is NOT original, what did you swap from another!
Requested earlier.........
Post your screen image at the Modules tab.
I want to know where you found that spreadsheet. A direct link is required.

i only tested with a second spare fuse panel, i put original back in. everything is original in the car, nothing was been changed.


i'm not sure which spreadsheet you are talking about. i'm new to this forscan.

once again, thank you for your help so far

One point you made a while back:
"4. Any changes I made, have been reversed right away."
What changes? and that statement asks if you used some type of "internet spreadsheet garbage and deeper than rotten poutine" information.
Something happened to that network, what did you attempt to change before this insanity?
Was it the extra lamp installation?
Did you scan the car before you changed anything, was the scan clean and fault free?
You need to go back to the scene of the crime.

The network view looks normal for this model but those faults persist.
How long have you had this thing?

Ok I’ll make up some dates to help.
June 1- no issues with the car. Scanned
June 2 - I want to install fog lights, I order a kit.
June 4 - I install kit. And hook up using a fog light kit.
Fog light kit requires power from battery and ground. Then runs a switch inside for on and off. Instead of using on/off switch. I used 12v from the headlight connector. The on/off switch required 12v to the switch then it ran to the relay.
Everything turned on and worked. Lights were on and working then with those lights on I installed all slash shields.
When completed. I tried to turn the car on. Battery was to weak, so I jumped my booster pack.
Once started. My left turn signal was on solid. It was on for a few minutes. I turned the car on and off.
The turn signal disappeared but my turn signals or hibeams would not work. My wipers only worked on hi speed.
My steering controls would not work. And I got the system shift fault.
At this time, I removed the fog light harness and put everything back to normal.
Still same faults.
Left the battery disconnected.
June 5- connected the battery - no change
Checked all fuses- all good
June 6 installed spare fuse box- no change, installed original fuse box back - no change.
Once again checked all fuses- all good.
June 7 used forscan to reset modules. I was able to reset all modules besides PCM. No change
June 8 went into ipc configuration and made a change, change was successful and converted back to original. Confirmed I was able to talk to every module that is coming a communication fault.
June 9 tried to do the asbuilt on different modules, I wrote to as built settings.
Used the website- confirmed everything is correct.


So when I said I made a change, I just made a change to test.
All the tests as good, I can talk to every module.

I strongly believe this had something to do with the fog light installation or low battery after.
I have a good battery now and no fog lights installed. Fog light harness has been removed.

I get the system shift fault. But I am able to drive the car, the car shifts perfectly fine.

I read somewhere the sccm could cause this. But usually flashing the high beam or taking out fuse 13 on the BCM will wake up the module. No luck with me.

The first mistake was using the headlamp switch to control the extra lamps.
The current was reversed back to the BCM.
The second mistake was the voltage spike introduced to the dead battery with the jump pack.
You need to explain that IPC change, what was it?
If that thing was in the shop and in that condition, it would receive a global update for all controllers on the network and overwrite everything in its entirety.
That type up update will require two known PATS keys.
An update / rewrite will take a dealership or Motorcraft subscription with a J2534-2 device.
I would name this adventure as "flipped bits".
After that, scan the car for the remaining faults if there are any.
If any faults return, it's an indication of hidden damage.

I did not use the headlight switch, I used the 12v that was feeding the light bulb. Right at the light bulb. I tied into that.
The 12v that was powering the low beam also turned on the relay for the fog. That’s it. Nothing else was used.
My headlight switch works as should.

I went on the asbuilt site and compared the site to what I have showing in the modules. Everything was good. Exact same.

The iPC change I made was disable driver belt chimes.
Then enabled again.

This car was never in a shop, it’s in my garage, sitting for the last 3 weeks + well I try to solve this issue.

If it’s hidden damage, which Module is damaged?
I strongly feel I may have some issues with my sccm.
I just not sure how to confirm this.
