How To Test IBS Module?

[SparkleTooth]

I'd be interested in Aux bypass as well. I think I need some convincing from those that have done it, without any new issues.
I seriously have had it with this whole ESS crap. I don't use it, but the fact that it doesnt work the way it is supposed to makes me always worry there is an underlying issue that will leave me stranded one day.

Curious, why complicate things, and not instead do, the simple aux battery by-pass procedure, that takes a mere 5 minutes to do and it's free?

Plus with this procedure, you can always leave the aux battery occassionally topped off, and use it as an emergency back up battery if the need ever arises!

When I think about the change from OEM to Genesis, I only see this extra upfront cost, but not extra complication.

The additional capacity the second full size battery provides is worth dumping the OEM system.

With that said, I have not made any decisions as yet (other than almost confirming I need a new high amp fuse array).

As of yesterday I have had my Aux battery bypassed for over 72,000 mi..

I did the aux bypass in very early 2019 and have not had any issues at all running with just the Main battery. No EVIC notices, nothing.

Yes, on a rare occasion I still use the ESS feature. Rarely though.

Just know that the aftermarket dual battery set-up is still a set-up that you have to maintain and deal with.

Guys think that going from the stock dual battery system to the aftermarket dual battery system and then no worries, no maintenance, no more battery woes.. they are grossly mistaken.

Ok so even though I just replaced both my batteries less than 3 weeks ago I think I am going to attempt a bypass/delete today since I already don't trust the aux battery.
Here is what I plan to do based on several videos I have viewed on the process: (Keep in mind this is a diesel so aux battery access is way easier):

1. Remove Main Battery
2. Remove Aux Battery
3. Take Aux Battery Pos and connect it to Main Pos
4. Take Aux Battery Neg and connect it to Main Neg
5. Install Main Battery reconnecting Pos and Neg (With the Aux Pos and Neg connected to it)
6. Disable ESS with Tazer

There should be no removing of Fuse 42 with this setup.
Do you see any issues with this process?
Thanks

Is your JL still under warranty?

You have a brand new Aux. Keep it in place as a b/u for the Main, should the Main deplete..
The bypassed Aux is easy easy to maintain so it is ready if you need as a b/u.

Especially if it is still under warranty, just do a simple Aux bypass. When you are out of warranty, then if you feel the need, delete the aux battery.

I myself do not feel the aux battery delete is the way to go for most... Depends on the guy/gal, how long they keeping the JL, do they have a warranty, how handy they are, do they want a b/u battery in play and more.

By the way, Tazer JL does not disable ESS but indeed it in essence does the button push for you... remembers state button was in when JL was turned off.

Yes Jeep is still under warranty. Ok I will just keep things as they are for now and monitor.

I just find it ridiculous that two brand new batteries (DieHard AGM) still gives the "Battery Charging" message for Start / Stop. I don't use Start/Stop and its the first thing I turn off when I get in the Jeep, but its the simple fact that it makes me think there is a bigger issue to chase down and Frankly I am tired of chasing electrical issues on this thing.

In conjunction with @SparkleTooth's post (and apologies if this has been covered countless times), but to turn off start/stop and to do an "in-place" bypass of the auxiliary battery while leaving it in the Jeep, are these the needed tasks?

1. Remove F42 fuse.
2. Remove auxiliary battery negative cable from main battery, insulate it, and store it out of the way.
3. Install Smart Start/Stop.
4. Periodically trickle charge auxiliary battery--I assume this can be done by connecting positive of charger to main battery positive cable and the negative of the charger to only the auxiliary negative cable.

Did I miss anything @Rhinebeck01?

Will there be any EVIC errors related to ESS?

Did you get the message I sent you? Read all your messages.

Missed it...let me check.

There will be no EVIC messages.

To trickle charge the Aux battery, hook up your battery tenders negative clamp to the disconnected ESS negative cable and the battery tender's pos clamp to the Main battery positive. That will see you charging just the Aux battery.

You do not need to buy a SmartStopStart unit or use a Tazer JL to do the button push for you... Just do the button push as it is best to minimize use of ESS if you are running with just the Main battery... BUT, you can still use ESS on occasion if you want..

Do not wrap up the ESS negative cable with electrical tape or such. Cover it with a piece of rubber hose, a piece of plastic wire protector, etc. so you have easy easy access to use that cable.. Keep a nut on the neg terminal should you need.. I use wing nuts.

The genesis dual battery system doesn’t void your warranty. My dealer services my vehicle and no problems. The comment was made, why didn’t they do that from the factory. Watch Shane’s video.

I totally disagree.

Anytime you bastardize anything .... again anything, especially anything electrical on a vehicle, you risk warranty issues.

Much depends on the dealer... or if a major issue arises how Stellantis, if they get involved, takes to your bastardizing/ to your mods..

I just replaced my Main and Aux and it was fine for a few days, then it went back to "Start / Stop not ready battery charging". After a long drive it goes to a ready state but not all the time. The charging system on this jeep is just maddening.

I may end up replacing the High Amp Fuse Array just for the hell of it to see if that changes anything.

I have a Grand Cherokee doing sane thing

Charging systems are clearly more than FCA can handle the complexity of........Makes me weary of anyone jumping on the 4xE bandwagon. They still haven't mastered the standard 12v car battery.

I hear you. This is the first time I have had this issue and it may be "all me" meaning that I caused the N3 to blow.

I will see how it goes, but my next step would be to go Genesis Gen 3 (not because of the fuse, but to eliminate the aux battery).

I will have to do some additional rewiring for the relays on my Baja Designs & ROAM step lights as well as the winch disconnect but that is not a showstopper:

Baja and ROAM relays:

Winch Disconnect:

@CarbonSteel If you don't mind can you elaborate on how you mounted the winch disconnect?
When I installed the Genesis system I moved my Roam relay to a spot I'm happy with but my winch disconnect location I'm not pleased with. I like where yours is located. Feel free to DM if this is too far off topic.
TIA
