2019 F550 Trailer Running Lamps INOP

[@joshmarquez8485]

Mines doing the same problem, but I’m getting 14v at my module 😓

[@JasonTheMunicipalMechanic]

I have a 16 550 with a message trailer connected then left and right turn signal fault then trailer randomly disconnected, with no trailer ever connected. I figured I have some corrosion somewhere. I haven’t looked at it yet but at least I know where the trailer module is located. Thank you.

[@PowerStrokeTechTalkwARod]

Probably not ur issue but yes I would definitely check your circuits back there....specially under da dump!

[@JasonTheMunicipalMechanic]

PowerStroke Tech Talk w/ARod does the trailer module not send out a bias voltage? I figured it was like a brake controller that sends out a bias voltage and when the trailer was plugged in it grounded the bias voltage telling the module the trailer was plugged in. I though there might be corrosion dropping the voltage but no extra load on the turn signal circuits making it fault on those circuits. It’s just a guess, we don’t run any trailers on it so it’s not really a problem I just hate error messages and cel’s

[@prospexican]

and did u got any fault codes?

[@chrismiller9611]

I just encounter this exact problem and symptoms on my 2019 F250. 2.6-3.2 vdc instead of the 12.5vdc. I will get a new module but where to obtain the latest firmware?

[@scottchalfant7336]

Thank you for sharing

Hello, I have a question I have a 2019 F350 and I have no auxiliary lights to my horse trailer. It has a switch for the tack room and sleeping area. No power. Battery charges and everything. Trailer was tested at dealer, I don't have auxillary light power from the truck. I cannot figure out what fuse it is or what is wrong. I am thinking its the same problem from your video but i have no idea. Any help would be greatly appreciated.

hi, im working on a 2018 F-350 6.7 4x4 crew cab, for one of my customers, it has the trailer control module, but according to diagrams the bcm prime the internal bcm relay to prime the unserviceable trailer control relay, which is inside the ft juntion box, i suspect the last relay went out since acording to diagram the trailer control relay gets power from trailer control relay in juntion box, and if i unplug the TRM and apply power to brown ckt then i have power to trailer parking light system. any help or recommendations?

[@jsnowstorm1311]

I have a 2011f550 with no trailer the message comes up trailer wiring fault. I am thinking they used the trailer wiring to run the lights on the dump body. So it could be this module..?

[@PowerStrokeTechTalkwARod]

Ehhhh i dont think so...

[@saulcalvillo1827]

How much this trailer module in the dealership bro ?

[@PowerStrokeTechTalkwARod]

Beats me bro, I don't work in the parts department

[@greenbean6739]

Can this be a plug and play replacement module? Or do you have to go through the programming?

[@PowerStrokeTechTalkwARod]

Programming

[@kenhews331]

I messaged you several months ago about my truck and you told me several things to do to it and that was what was wrong with several things you told me but they are still something wrong with it i have put new filters in gas tank, put new fuel pump, ICP, new rebuilt injectors,new valve cover gasket and harnesses new CPS and all the parts were genuine Ford parts motorcraft and it won't run on nothing but starting fluid when you stop spraying it it will run a few seconds and then start to have a knocking sounds from the injectors could it be the ipr or hpop going bad i have about giving up on it any help would be appreciated thank you. Buster

[@kenhews331]

Oh yes and i sent the PCM and IDM off to have them tested the IDM was good the PCM had a few problems and they fixed them

[@PowerStrokeTechTalkwARod]

You obviously are not getting fuel hence it runs on starting fluid. Is the bowl filling up? Maybe your not achieving injection pressures...

[@kenhews331]

@@PowerStrokeTechTalkwARod i don't believe it getting injector pressure would it be the hpop or IPR it's getting 60 psi fuel pressure

@@PowerStrokeTechTalkwARod thank you very much for your response i will try them both and hope that fixes it if it don't I'll probably give up on it and sell it for what i can get out of it but i really like the truck thanks again and i watch all your videos and think they are very good

[@brianpetersen3262]

Thanks for the info, I am having the same issue on an 18 450, also the 12v charging circuit is inop. Does this module also regulate that function?

If you like to compensate me visit my email [e-mail]

[@jamest327]

You must have tested voltage of the running light circuit pin out at the rear of the vehicle before proceeding to the module under the dash? Or did the eManual immediately send you under the dash?

[@Itsa_Mea]

1:19 he says he verified at the 7 pin connector it was only getting about 2 volts.

[@PowerStrokeTechTalkwARod]

No, i verified their concern, @ the rear round standard 7-pin....then proceeded with my own PPT upstream of the supplying circuit....which determined to be a failed TRM.

[@gobdeep]

When replacing the module, was it necessary to use IDS or could you have simply swapped the module with no computer programming?

[@PowerStrokeTechTalkwARod]

Nope, an IDS must have. All these new modules hafta being configured to the truck with As-built data in some cases

[@albierumfelt3372]

What if you bought a used one from a wrecking yard?

[@PowerStrokeTechTalkwARod]

Ehhhhh

[@natey891]

Do you have a link where to buy the voltage tester you used?

[@PowerStrokeTechTalkwARod]

Sorry i dont. Look up the Power Probe brand.

[@bradniesyto93]

Did you replace the trailer running light fuse too? Idk what happened but the running lights stopped working on my dump trailer and it popped fuses in my 2019 and 2006. Took trailer to dealer and they replaced front harness but couldn’t explain why it happened... I can’t wait to test my trm tomo now

[@PowerStrokeTechTalkwARod]

Lemmie know brother

[@gobdeep]

Something similar is happening to my trailer. Every light on my truck is LED but my trailer is all incandescent. I am replacing my trailer light housings with all LEDs. I’ve seen weird things happen with mixed LED and incandescent setups.

I work at a Chevy dealer. Must say ford has this figured out better than Chevy does. Chevy mounts the module above the spare tire carrier. Stupid. Gets covered in salt, I’ve seen 2016s with holes in these modules from corrosion and service trailer brake message on the dash.

You can as built data any module if you cant exhale the old data from your module ur trying to replace. Horror stories.....1. The foolios shlda known it was deleted to begin with 2. Thats what mister customer gets in the first place...programming others modules in the body, do not affect ECU programming.

After the module replacement and programming, you test with lights off and it still puts 2.4 volts out? Why, is that why it cost $300 for new batteries? This constant drain? Love your insight. Great channel.
