Thanks for writing this up, lots of good learning info here.
I do not know if my 2018 has the PCM patch, is there e way on the vehicle to find out, or do i need to take it to a dealer?
For the N1 N2 jumper, what part do I need? Is this a pre made item I can purchase?
Have you tried looking at airbnd or that other outfit v-something? Senator Highway is nice, Broken Arrow in Sedona is better. I doubt snow will be a problem here, usually January is snow heavy. Another idea is to call Summit 4x4 in Prescott and talk to Jesse or Colton for ideas.
Today I see the Genesis web page states " Odyssey Extreme series 25-PC1400 has been discontinued as of July 2020 ", instead they offer the Full River FT750-25 battery. I have never heard of this battery. Is anyone in this thread is using it or heard if it?
The posts here are very good, I will add for my situation with batteries, I bought the Digital 1200 12V Performance Battery Charger and Maintainer when it was on a really great price (using Honey on Amazon). I have found this works great and I no longer get ESS EVIC messages.
Thanks for posting this. I am soon to get two Genesis systems (for two JL's) and have been reading everything I can. Unfortunally, I am finding I still have much to learn about the JL battery and electornics, and reading about solving factory PSO items is a slog. Keep the info coming!
