...and the funny thing is Nick that forum members have reported that more recent 3.6L JLs have an alternative cold crank procedure design whereby if either battery has sufficient power the rig will crank.Turns out the tiny ESS battery is more of a weak link or achilles heel then eTorque. People are more likely getting stranded by a bad ESS battery and / or charging system then anything else. I herd about 40% of all warranty problems are ESS battery and charger related. Problems with it can cause all kinds of seemingly unrelated problems to happen. All kinds of warning lights seemingly not related to the battery or charging system? I herd there were some changes between the 2018 and 2019 ESS systems.
Accordingly I asked above for the FCA group of this thread to explain if the logic has changed, and if so, has this/will this change be uploaded into the older JLs.
I would think that this logic change could be handled without anyone having to open a hood or change parts.....rather, handled with a download or dealer reconfig.
