  1. Hybrid: which battery powers which systems? Is there a list?

    12VB powers the 12V system (everything that may turn on) - if the truck is off or key is in Accessory position (for push button start - you don't get this mode truly it appears, without a bunch of things done just right). HVB powers nothing until truck hits On or Started. Which the 12VB throws...

    Perhaps by then they'll have a PHEV version! Many are wishing for it too.
  3. Auto AC is weak when it is hot outside

    Funny that the 25MY is the one that will actually auto-turn on the HVAC and have the AC button pressed, when that's not how it was left. And it seems 2 comments in this thread for the 25MY acknowledge there may be a lag time, for a very reasonable purpose - don't max circulate hot air, until...
  4. HYBRID 12V Battery Mystery SOLVED

    So you did both at the same time?
  5. Odd tire wear, possible alignment issue(s)?

    Yep. And I had no pull either despite back toe being at the range extremes. That tire after 2 rotations just had more wear. I tracked the /32nd's in my notes. Wasn't until that thicker much newer tire was put on back right, and/or more worn tire was put on front left - then it pulled. I even...
  6. HYBRID 12V Battery Mystery SOLVED

    This thread isn't really about dealing with parasitic draws (non-desired higher amp), usually those are intermittent. Those don't actually seem to be striking that many. But when they do, an already bad health battery is going to be impacted more than a good healthy one. Microdrains are...
  7. HYBRID 12V Battery Mystery SOLVED

    Your cycle down to 12.x (12.8? if reading is correct) was probably when it was thinking a fully charged battery was obtained. So little to no charging amps. That's when the test with fan @ 6 or headlights on would show the jump back to 14.x and more amps given. But sounds like your battery has...
  8. HYBRID 12V Battery Mystery SOLVED

    Just for clarity that's a battery sensor attached to the negative post, with wires going to the BdyCM which handles the BMS function. While it obviously senses amps going both directions charging and discharging - it only logs in the BMS charging while key on. I do have proof. External...
  9. HYBRID 12V Battery Mystery SOLVED

    I got no inverter module either. I'd also be curious with 22MY compared 24MY - the BdyCM. The strategy level. Not sure if that is scanner speak, otherwise known as software version, or if that is a different thing, and I can't read it. BdyCM - Body Control Module Bus: HSCAN Part number...
  10. HV Battery does not charge in Neutral

    The Generator motor needs to spin freely in neutral when ICE is running. Therefore no charge is given to it in order for the normal effect of it being a generator to recharge. Park has a pawl to hold it in place while the generator does it thing. No ICE running? Then the HVB is powering the...
  11. 12v Battery charge percentage setting?

    Hey - curious if you saw a difference - or looked at live data to see if battery held at that higher SOC% now?
  12. Hybrid thoughts

    Many multi-car families do that - EV for the daily driver, PHEV for the long trips when needed - daily driver for whoever goes shorter. If only 1 car needed & you do rare long trips - EV & rental when needed. Or enjoy charging along the way as part of the trip.
  13. Effin' Screw Up

    They send it with the ticket - like a toll charge mailed - as proof it was you.
  14. HYBRID 12V Battery Mystery SOLVED

    See my post before with several pictures. There is NO tracking of external charging. Only with the key to On position, or pushbutton the same. And that would be a bad thing actually, to count that in the math. The BMS will see the end result of doing it - higher Voltage, after a rest period to...
  15. Odd tire wear, possible alignment issue(s)?

    I noticed the same thing at rotation - backs worse, right back worse yet. When I had a sudden pull start, I took it in for alignment after some time - they found no issue - they tightened up the front toe though. It was after another rotation I'd done, and putting a very new replacement tire...
  16. QUESTION: Full Size Spare Tire Touching Rear of Factory Trailer Hitch

    What is the actual size of that full size spare? That term has meant several things thru the models it appears in many posts. And is required for an actual compare.
  17. Hybrid thoughts

    Need to idle? No. It prefers to idle, enough so if you start driving it'll use the EV system for 30-40 seconds while the catalytic converter gets up to 1000 F, unless you are just punching it for power before that. Unless it's too cold to draw from the battery to use the motor. But do you punch...
  18. HYBRID 12V Battery Mystery SOLVED

    That would be the 9 hr locked Relearn process to discover that. Disconnected for the charge up may have forced it that night when reconnected. Which would still be a good reason for doing it that way. Otherwise the normal schedule for the Relearn could be 1-2 days away.
  19. HYBRID 12V Battery Mystery SOLVED

    It's been proven multiple times by those with scanners. 80% is NOT max charge. It keeps charging above that. Float charge, below 1A. Or in the thread you are in, picture proof with no change. And it's been shown by those that changed the setting - did NOT get charge levels such they suddenly...
  20. HYBRID 12V Battery Mystery SOLVED

    And Michigan! Pretty sure you enjoy some cold months. Examples like yours is why I think mine has a bad battery sensor.
