2024 Hybrid 11,000 miles 2nd battery died Also want to reprogram ABS module for $200

[HeyBales]

I have a 23 hybrid on its 4th battery I have had every module updated and every time applied. There is still another unintended leak, and the underlying problem of never getting to even 80% charge. The 23 and 24 are identical electrically. There is another tsm solution coming in q2 fi tsm54519, and nobody gas announced a fix for the 80% charging causing the battery to always sulfate.

I think we have a bad sensor.
When on a new battery, it charged above 80% - at float charge, to 85%, 12.8V.
But ya, once it starts to lose it - forget 80%.
My BMS new goal kept dropping until now it appears to be 50%, but it's having a hard time reaching 45%, and resting was 11.5 this morning.
It's about to blow! I mean go.

You have access to Forscan Lite, or Regular?

Rarely ever use EPB.

Never had the intermittent drain.
(obviously I have other problems. the BMS too!)

Interesting they don't have software solution yet - which means they must not know yet exactly what kicks off the process incorrectly in the first place.

I'm going to have to have someone put the EPB on to see if I can even hear it clamp outside the cabin.
Pretty sure I've not heard it inside when I have used it.
In which case, unlikely to hear the motors doing the adjustment routine.

I'm picturing something really sad - give the backoff adjustment say 5 step levels.
Measure, but the result is between 2 levels exactly.
ABS can't have that, remeasure.
Again, nope, repeat.
Ugh, nope, repeat.
ABS - I'm going to keep this up while I got juice and get an exact level.
Fail!

@johnDeere - Got another fuse/module to measure draw on now!

ETA - actually I can use the Forscan Service to calibrate EPB, and see if I can hear it.
Can't recall anyone ever saying while walking by truck they heard noise or clicks from the rear wheels soon after park & lock.

Oh yeah I could hear it easy enough.
I guess never put on the EPB while silent in cabin.

Now - running the Forscan Service to enable EPB - fine.
Disable EPB - fine.
Dashboard gave message about an error in brake system though. Oh crap. Set brake lite.
Tried using EPB - fail.
Ran service to reset the ABS Module - fine.
Dashboard gave message about an error in brake system again. What did I do now.
Tried EPB again - fail.
Key Off - key On - all good.
Yikes. Kinda need to drive tomorrow, sooo.

It is not.
That literally applies pressure to all 4 brake lines.

EPB applies none. Hence the motors.

Thank you! Good to know.
