JScan vs Tazer vs Flashcal+ my experience

[Bayrat]

If you do this, you've only removed the small battery from the circuit. Unless you push the button the ESS will still attempt to function, but will pull from the main battery instead of the small one.

You still need to disable ESS, either by pushing the button or by using SmartStopStart/Tazer.

You need also to pull the fuse and it will no longer operate. I'm not going to search for it, but the thread explains with pictures exactly which fuse to pull.

Actually, I did basically the same operation on my 2018 Grand Cherokee and it works flawlessly. No more SS, no more button and no more small battery.

False.

I bypassed AUX years ago (same fuse pull method you’re talking about). If I allow it, ESS functions just fine and will use only the main battery.

@Bayrat

This is incorrect... When you do an Aux battery bypass or delete, ESS still works when you are running with just the Main battery.

I have been running with just the Main battery for about 60,000 or so miles.... since early 2019.

My error, I missed that. I traded my 2019 JL about the time that I saw the disconnect thread, so never did the process. My 392 does not have SS, thankfully. However, he can still use the hood switch trick to disable it if so desired. Oddly enough, my 2018 Grand Cherokee SS has never operated since I modified it, and disconnected the small battery. For that I am grateful.

Totally agree with the 2 device approach.
Jscan etc for permanent stuff, tazer for the mega features.

Guys: my 23 JL Diesel had an electronic melt down a couple of weeks ago. The dash lit up pulling out of my driveway, ignition locked, and I had to have it towed to the dealer. Zauto told me to unplug my Tazer even though I couldn’t unmarry it (because the ignition was locked at off). Battery ended ip going dead at the dealer the same day (I believe the screens were locked on).

They had it 9 days and couldn’t figure anything out. After completely disconnecting the batteries, it started.

I brought it home and immediately plugged the Tazer in and unmarried it (at the advice of Z auto). Now, ironically, the ESS system does not work at all (which I applaud, as that’s the main reason I bought the Tazer). But, my added-on paddle shifters don’t work (which I now know is because I unmarried it).

My Jeep was upfitted by AEV at AEV, so their Procal is what manages my tire size and axle ratio.

The Flashcal+, with its app, surely seems easy to use. But I’m worried: I think my Tazer went haywire and caused my ignition to lock up. But I need to activate my paddle shifters. Can I do that one single feature with a Tazer, then unplug it (without Unmarrying it?). Then can I plug in the Flashcal+ and use it for ESS and the lockers and RPMs, etc?

Thanks in advance. My Tazer still isn’t in but this weekend I’ll plug it in and see if I can get the ESS to reset, and get my paddle shifters working again. Side note: can I just pay the dealer to flash-on my paddle shifters? If so, I’d eliminate the Tazer altogether.

 

[XtremeRetard]

I believe jscan can turn on the paddles.

By the way jscan cannot disable Rubicon lockers, tazer can as it actively manages the errors resulting from axle removal, jscan does not....

Back to why both devices cover more bases than just one or the other..

Okay I did more homework this weekend, and Rhinebeck01 was gracious enough to give me some feedback as well on the phone.

When I remarried my tazer, my radio dropped out every 3 seconds for a half a second, and my reverse camera on my radio screen had odd lines across the bottom and down the right side (like an old tube TV). When I unmarried, both went away. My ESS is still completely disabled (which I’m happy about), but Rhinebeck doesn’t think that’s related as that feature of ths Tazer should only be present when it’s actually plugged in (and it’s not).

So I still think that my Tazer went bad and/or has a software glitch. I will ask Zauto to either replace it, or tell me how to wipe it and reload the software. Stay tuned.

Bob,

Curious if you ever came to further conclusions as to what the issue was and whether the Tazer was involved?

(Originally from St. Louis myself. Are you? I'll have to ask you the where you went to school question? LOL)

@zautomotive would not reply to my texts asking them for a warranty replacement, even though I’m a dealer of their product. I give up on the Tazer. I was a big fan, until I wasn’t. $300 waste of money at this point. I haven’t had a single incident of any sort since unplugging and unmarried the Tazer. I bought the $40 scanner and the $25 license to activate my paddle shifters.

And ironically, my ESS remains disabled, which was the main reason I bought a Tazer to start. Somehow, it’s permanently turned off, even though it’s claimed that that feature can ONLY work when the Tazer is plugged in. Well, there has been no other module of any sort plugged into my Jeep and my ESS is permanently disabled. After the issues I have, I don’t think it’s coincidence. It is my opinion that my Tazer went bad and caused the ESS to stop working (which for that, I am thankful. So maybe the $300 paperweight was worth it!! ??‍)

Disabled as in “I start the Jeep and the button is illuminated,” or “I start the Jeep and the button is not illuminated, but ESS never kicks in.”

I am guessing the latter which would have nothing to do with Tazer. As @Rhinebeck01 pointed out, Tazer *must* be plugged in to make the ESS button retain its last state.

I’m also making the switch from Tazer to JScan, but not because I’ve ever had any issues with Tazer… been running it since June 2018. I’m switching because I already own a SmartstopStart that’s collected dust in a drawer and really don’t take advantage of 95% of Tazer’s features. (When I purchased it there was no other way to disable ESS. Later I bought SSS for a great price, but went back to Tazer because TraveLink alerts make me nuts. Now JScan can handle that so no need for a Tazer.)

I'm a St. Mary's graduate class of 1982. I escaped the Jesuits up until that point. But they got me in college.

Start the vehicle, no light, no ESS. So I don’t press the button ever, the light stays off, and the ESS seems to be permanently disabled. How else would that have randomly happened?

Yes, JSCAN to turn on paddle shifters. That’s all I used it for.

There were features of Tazer I loved. But not worth my Jeep in the shop for 9 days, and their customer service ghosting me. Adios Z Auto.

 

[OldGuyNewJeep]

There are a litany of reasons.

Scroll to the ESS “page” on the EVIC. What does it say?

One of many threads where this is discussed: https://www.jlwranglerforums.com/forum/threads/ess-how-does-it-work.61620/

1000% not a programmable setting. If it were, JSCAN could do it. To manipulate the state of that button requires hardware be plugged in at all times.
