Need help;
When I was driving my Wrangler today I noticed that ESS wasn't working as usual, so I went into menus to check ESS message and it says due to steep grade, so I went to check Pitch & Roll and it was showing 6° on level ground.
I was on my way to work so I dropped it off at the nearest dealer and the first thing they said was that they had no idea what is going on, this would be the first time they encountered this issue, then they asked if I had a suspension upgrade, which I did (Rubicon suspension swap + TF 0.5" front/rear spacers), I also had 34" Falken tires mounted the other day as well. Not sure if these would affect my pitch by a whopping 6 degrees. Could flashcal also be the culprit here as this happened the day after I re-calibrated my speedo, and flashcal was giving me an error that ABS module could not be initialized.
Does anyone know what the problem may be, since the dealer is pretty much clueless on this issue as well.

Update on the issue, it is caused by Flashcal screwing up the ABS initialization module during my speedo calibration/tire size, the dealer reset my ABS module and now it is displaying pitch and roll correctly...

So now I have to deal with incorrect speedo... or messed up ABS module..

@Superchips JL Can you guys provide some support regarding this issue? My flashcal is updated to latest version..

Resetting the module resolved the issue for me.
