I just confirmed that you can run HIS and PPO at the same time. I was only running small loads, but I dont see any techincal reason why they can't all run at the same time. The only issue is that PPO requires the truck to be on. The HIS transfer actually turns off the truck, and thus shuts off...

The communication issue can be intermittent. It certainly can ping its location to the ford server and then cease to work further. I have seen that many times. I wonder if you were to start the truck now if the other communications would work. Having things work at random times has been the...

Yes they all work outside of Bluetooth range as well but that will be consistent with the rest of the connectivity features. I guess they need to clarify how far from the truck they are trying these. There is also a case where connectivity works but the truck will have terrible cell service...

What you are describing are Bluetooth issues and have nothing to do with the modem issues we have discussed. I would turn off Bluetooth on your phone and back on. I can say for sure the mechanism is different because I can have none of the connectivity working but the app still works for...

I have had it crash more often when using Alexa than any other time. Sometimes it crashes mid song. Other times it is the exact moment it changes from one song to the next. I am actually going to try disabling Alexa during one of my tests and see the results. The kids will hate that, but it...

So after pulling fuse 32 and going on one trip of about 2 miles, the modem was locked up again when re-starting the truck. Interestingly enough during that time I received the karaoke 10.1.0 OTA. I believe this is why I say that fuse 32 is not a reliable solution though. I believe there is...

It used to flash for a second then go blank. Now it redirects me to an error page (for days and on multiple devices).

No it really is one large fuse. There is nothing that actually says 8. It really should say 8/9.

It is a 2023 MY, although it has an october 2022 build date. Upon looking at the actual fuses it seems that fuse 8 and 9 are the same physically.

When I go to the site, it just shows this message now.

So I had my modem locked up all day, and just went and pulled fuse 32, which reset both my radio and my modem (it seems). I will say my comment on pulling fuse 32 doesn't work goes back to before I had fixed my battery voltage sensor, which I do think contributed to some of the issues. I will...

I don't seem to have a fuse 8. The Fuse box goes 4,5,7,9,11, etc.

@PrimeRisk @TaxmanHog . Do either of you use Apple Carplay normally? How about the Alexa built into the truck. I have suspicion that either of these or both are causing some of the modem issues. Just curios to see with other people that have had issues and those that have had no issues. For...

To be honest, the truck has been working better since the more recent updates (just prior to 6.14). So much so that I let the truck go past 36000 miles without bringing it in for that specific issue. I actually thought they finally fixed it. Recently I have been having more issues again. The...

correct. I pull back the trim piece behind the rear passenger seat and pull the plug directly. It is significantly faster than pulling fuse 32 (which doesn’t really work by the way) or pulling off the 12v in the frunk. It also requires no tool (now that I leave the holding clip off). I am...

My modem fails all the time and gets locked up. Some trips or works fine and others it’s locked up with no internet connectivity. I usually have to reset it by pulling the plug and re-connecting it. Like you the sync reset does nothing. dealer wants me to leave it for 3-4 days just before...

Exactly this. The Delta inverter is a 400v system and has no issue sending energy back the the truck. The truck does not display what is going on properly but it is working. In the video he notes that it charged 4% while on the HIS off grid. It would be slower than the level 2 AC charging.

Here is the thread with the YouTube. Video a few posts down. https://www.f150lightningforum.com/forum/threads/his-with-ac-coupled-solar.16888/

Actually it does work that the truck will charge through the DC connection if there is excess solar in off grid mode. Someone here has already confirmed it (in one of my previous posts) and I am going to verify in the next couple of weeks.

So I just self installed the HIS myself and have it working. I believe your truck needs to be at the 6.14 update though (which is when mine started to work). My system is not registered with Ford but I am now getting consistent transfer to the backup panel. The delta equipment works great. As...
