This happens when you program the HV Battery voltage xgauge for the TBCM PID, but it reads the TCM PID. The scaling for the two differ by 4X. The 84-94 readings represent 336-376 Volts. Changing the xgauge to read from the TCM should fix the problem, but as far as I know this only happens with the 3.15* versions that can't talk to the TBCM.

 

Thanks Carl. This was for sure with my plain 3.15. ( no * )

Also, in my 2005, the volatge is very slooowww to change.
It parks around 336v and only changes a couple of volts after many minutes of driving. In the 2006, the voltages were changing rapidly, ( like every few seconds ) but always in the 84-94 range.

This would indicate ( as you said ) swings between 336-376 within seconds, something I've never seen on my 2005.

Which one is working "correctly"?

On both cars I used:
TXD 074522490B
RXF 04620549060B
3010
MTH 007D40000000

Using the raw HEX on my old SG, I would see wide swings ( in HEX ) per second, depending on charge or discharge. The data seems "buffered" now with Xgauge.

Carl, Info Only: my SGII-XG is Ver 3.15 (no *), and on my 08 FEH AWD, SoC reads in the 33x range with TXD beginning w/0745, and with TXD starting with 07E1, I get SoC in the 80+ V range. So this anomaly also exists in the 3.15 firmware version w/o the asterick.

Over the past several months, one listing on Ron's website showed 07E1 for a brief period of time, and I was monitoring it almost daily for hopeful changes to the BTM entry. That's when I saw the one time chg to 07E1, and realizing mine was set to 0745, I changed it to 07E1 (thinking I was wrong), and when I saw the 80+range reading, knowing that was wrong, I set it back to 0745. Now I see on Ron's website (the last time I looked), both settings are shown.

Perhaps others have mistakenly set this Xgauge value incorrectly some time ago, and haven't noticed that Linear Logic's website now has both entries listed?
