HIS Intelligent Power Backup Related TSB?

[Steely]

Yesterday I went to test the HIS/IBP system by shutting off my main breaker and hoping that things actually work and found it did not... but this time it failed in a different way.

It appeared like power transfer was in progress, the truck relays clicked and it made some whirring noises, the FCSP started to throb the led green, but when I went in the house, no power. A few seconds later the truck clicked off, the FCSP went back to solid green, and nothing else. I tried a second time and got the same result.

Today I noticed there is a fairly new TSB that may be the cause of the issue. Is anyone else experiencing this, did something change over the summer to cause this? I haven't tested the system in a few months. Just wondering if its just me, and if I'll have to go to the dealer to apply this fix to get it working again.

@Jim Lewis might have some feedback for you.

@Jim Lewis might have some feedback for you.

I think @rugedraw might be a better person to check the status of @Steely's truck, and @Mike G is one of the most knowledgeable folks around on the status of the GWM update that's supposed to fix truck/FCSP problems and may have recently received the update himself.

I think I'm still "Waiting for Godot." Although my truck rarely throws DTC U019B, it just did so the other day! I haven't bothered checking backup power transfer recently. It worked a few months ago automatically during a brief storm outage. I figured I'd just "chill out" until I get the GWM update.

Before receiving the anticipated GWM update, I've been able to restore power transfer functionality in various ways, usually via a cold reboot of my FCSP. See https://www.f150lightningforum.com/...er-when-truck-in-deep-sleep.20843/post-411622

I'll have to try and check the codes to see if I have the u019b stored anywhere.

I talked to the local dealer and they didn't seem too enthusiastic about just applying any available updates without codes to go along with the associated TSBs. So if U019B isn't in there they probably won't bother to update anything.

My second attempt yesterday was after a full system reboot. Shut down the inverter, killed the dark start battery to shut down the FCSP, turned on the truck, force rebooted sync, turned off the truck, and it did the same exact thing. I tried again when I got home today, and again same thing. Looks like it transferred but no power.

I did just recently get an update (first since like March or April I think) that changed the menu, camera, and setting icons on the center screen so maybe that broke something?

The truck port LEDs may turn green, but no power is being transferred until they start flashing green, IIRC. If you have any lights near where the truck is connected to the FCSP, you can always throw the light switch on. That way, besides the truck port LEDs, the area will instantly light up when power transfer occurs (for me, the garage lights come on, and I can hear the water softener firing up).

So you would have gotten the short gateway update (manifest adjustment something or other) followed by the APIM update (new Sync update to 1076), and then last Saturday you might have seen a DCDC module update show up (in FDRS) that I thought was supposed to fix that power transfer issue...but since I don't use that function at all, it would take somebody like yourself having done all of those updates to find out if the problem is now solved.

I can tell you I don't have any more DTCs for powertrain components after doing those updates. So as far as I can tell, I'm all good and just waiting for the official rollout of BC 1.3. hopefully before the end of this year.

@rugedraw might still be limited in his access to our truck information, as of his mention last week in the research thread.

 

[Steely]

I've not documented every update but looking at taxman's signature line of updates seems to match up pretty well with mine right down to the 9/6 sync update. This most recent one wasn't like the others it was installed on its own in the background vs the expected downtime after key off of many past updates... Unless it didn't work as it should have.

 

[TaxmanHog]

I'm not certain this is an issue, but now that you have received a bunch of updates, possibly the charging scheme or presence of a departure time event is corrupted, if so that could be playing havoc with the HIS control process during your black-out test.

Remove all departure times
Remove all charging schemes.
Plug in the truck, retry your blackout test.

Just to follow up on this, the problem continues. No support from Ford's BEV team other than it is a known issue, please wait....

Is anyone anywhere else experiencing this same error symptom? Today's BEV CSR tells me that I have all the updates on my truck but still it does not work, i'm beginning to wonder if there is a hardware issue but no one is giving me any detail or wants to do any investigation. Can I get any help from @Ford Motor Company on this?!?!

Well, mine is screwed again. I've been working with a contact at Ford to try and get ourselves working.

It says "Getting ready to transfer Power" -then it shows the 0 of 9.8 kW on screen, and the truck makes lots of noises, but never actually locks the pins.

The only thing I can think of is a few months back we got a stink bug commit death by squish on the inlet, so maybe it's throwing the tests off before the pin locks?

*Dc fast charging works, as expected*

Also done a complete reset, and nothing. Not even disconnecting the 12 V battery for a while fixed it

Is that what is happening with mine or slightly different? I've not gone into the truck to look at the screen, but it acts like it is transferring power: the green LEDs throb as if transfer is working, the truck hums and buzzes like its charging at 80A, and then within a few minutes it clicks off with an orange ring flash on the charge port. Next key on, the instrument cluster has a warning "charge station fault see manual"

I've not DC fast charged, ever, so i can't tell you if that is working or not.

If they get it working please provide a detailed video on your channel so we can try it too!

 

[Aminorjourney]

Yeah, it's slightly different. I never get to green lights on the truck

The issue you describe sounds like it is an issue between the inverter and WHB.
I am making an assumption that the charger LED light is pulsing between dim green and bright green and the charge port light ring is doing the same. If that is not the case then it may be a different issue.

I would guess the inverter cannot see the WHB neutral for some reason. When you are flipping breakers to test the system, how are you doing it.
Assuming the main panel is connected to the WHB200 and then that is connected to the backup panel, you should be turning off the main panel breaker to the WHB as well as the one to the charge station. My first guess at your issue is that you are turning off a different breaker which is disconnecting the WHB from the E4-BDI inverter.

When initiating a transfer test does the light ring on the truck charger port stay white or does it quickly go off after like 10-20 seconds? In the latter case, you need to push the lock button in the middle of the ring, and disconnect and reconnect the cable (as per Jim Lewis discovery). That seemed to be an issue on the other system I was testing almost every time, but is not something I see on mine. I was able to jump start their system each time once doing that.
The ring should be staying white for a little over a minute before turning green.
