The trouble with a refrigerator is that the compressor cycles on and off and when the compressor is off there is practically no load at all. Depending on the time between cycles the truck may not see enough of a load and shut down. A constant load and/or a properly timed load (as mentioned in...

Yes, as I was saying, if the voltage actually dropped below 1 volt, that would indicate an incredible load....dead short, and there would be other, extreme indicators. However, it's still odd that it's only when I'm charging the HV battery. I do think I still have an analog meter around here...

So I've been paying close attention to my 12v battery which certainly seems a weak point in our trucks. To minimize problems, I, like many, keep the battery on a maintainer when it's not being driven. To monitor even more precisely, I've added a VOM voltmeter. In watching this voltmeter in...

Yes, I do understand. It seems, when sending out an update, the algorithm would FIRST isolate all unnecessary 12v loads to minimize power loss. Funny though, during that update, no fans were running....the only thing noticable was that pump (very noticable at that!). As to the PPOB...

Ok, thanks....confirms my thoughts. But why would it run continuously during a Sirius update? This makes no sense at all. When is it supposed to run? It's quite loud....I'm sure I'd hear it while driving. I do believe it ran the 12v battery down low enough to corrupt the update and cause other...

OK, I actually had questions about this on a thread about receiving OTA update 25.2.1.6.5.2 Sirius Improvements. While receiving that update, this pump on the right side of the rear differential ran for about 40 mins. I suspect that it runs on a 12v motor and may have run my 12v way down and...

Indeed much welcomed.....been asking for this since I bought the truck. Thanks so much! BUT, I'm not seeing it yet! The truck is within wifi and is on a maintainer to ensure 12v battery is full. I verified that I do have 25.8.5 and I have power cycled (and used PPOB) the truck several times...

Back to the original....PPOB shuts down prior to the set reserve limit: Yesterday I charged my Tesla with PPOB. It charged for 7 hours straight at 4kW....a fairly large load, with no shut down. Of course I did have the battery maintainer on the whole time. Next time I'll try it with no 12v...

You are correct. I, in fact, demonstrated that when I was trying to power my house yesterday. I had a voltmeter on the battery and monitored the voltage. It slowly dropped through the process and when it got down to 11.54v the truck shut down ("to protect the battery"). It would be nice to know...

Indeed the LVB seems to be a very weak point. But is that the whole problem? If so, it would seem an OTA to have the DC-DC inverter charge it more often would be the fix. When I charged our BMW from PPOB yesterday, it ran for over 2 hours at 3.8 kW with no problem. But, I had it on the 12v...

Wow...interesting stuff indeed. But, I have more to add. First, I'm a bit confused about this 30 min shutdown timer. Is that something that is only present if you've made the ForScan conversion to run PPOB if the truck is shutdown? Because I've never seen it....I haven't made that conversion...

OK, I am back in California and able to resume troubleshooting the PPOB issues. Again, are these issues only with the 2023 pro versions? Anyone else with a different model and having these problems please chime in so we can better identify specifically where the problem is.....why would this...

No, in fact, my truck, a 2023 pro, REQUIRES the truck to be "running" in order to use PPOB. And that is an interesting point. Obviously, with the truck "running" there is greater drain on the 12v battery....screens are on, I have to turn the headlights off, audio, Bluetooth, etc. But others, who...

You make a good point. The 12v battery could be at the center of all this. In fact, This whole problem began immediately after that Blue Cruise/Sirius 25.2xxxx update (as mentioned earlier) back in Feb or March (?)......during that update there was a motor/pump on the right side of the rear...

Thanks. Yes, my 12v battery maintainer is downstream of the bms and is always plugged in when I'm not driving my truck so I highly doubt the voltage is low and opening the app 1x or 2x per week could hardly deplete the 12v enough to require battery saver mode. I did run into this same thing a...

I'm still on the east coast, away from my truck....will work on this when I get back next week. I have been watching my truck remotely though and was disappointed when it went into " battery saver mode". I do have a battery maintainer on the 12v and am not sure why it would go into this...

You're getting warnings, but is it shutting down? Let it go and see if it does. Interesting that you too have a 23 Pro.......is this the only build experiencing this problem? What's different about it?

Well, didn't think I'd get another chance before leaving for the east coast, but decided to add miles to our PHEV before leaving. Set up PPO and set the reserve to 20 miles and started charging at 3.8 kW. And, indeed, it spontaneously shut down after about 45 mins (not close to the 2 hours...

Thanks for working on it. Good that it worked as it should, but we still know that there's still something wrong. Funny though that my latest sessions had it stop after about 2 hours. I will time it more precisely the next time I use it. I do know it's stopped short in less time, but that was a...

Again today....same issue PPO shut down after about 2 hours. It does seem that around two hours now is the shutdown point.....although it was a much shorter time a month or so ago. It doesn't seem to be consistent. This time I manually set the "reserve" level to 20 miles and the PPO shutdown at...
