Well I am thinking I need to take my Jeep in for a battery issue, I have made a few posts about my battery voltage reading high all the time but several said you can’t go by the reading on the EVIC and the battery system have a IBS ( Itelligent battery sensor) that senses when the battery needs charging and then allows the alternator to charge accordingly, well when I first got my Jeep the voltage use to jump up and down and I found out that this is normal but now it’s a steady 14.1-14.3 all the time but always has started and it’s been this way for months
Well after seeing lots of posts on ESS issues and then hearing about bad IBS sensors and bad ESS batteries I did a test, I went into my Tazer and turned the ESS function back on and after doing so I now get a message that says ESS not ready battery is charging and I’m guessing since it’s showing 14+ volts all the time that something is wrong like maybe the battery sensor is bad or the battery itself is bad but it’s never not started and the voltage showing 14+ has been like that for several months so what say the battery ESS experts out there
