On my 3rd Tazer JL Mini.... Please help

[JeepOfTheseus]

thank you! I’ll try these tonight. I did do this before but the jeep didn’t read the Tazer. Like I couldn’t get to the control menu via the radio. Does that make sense?

This happened to me, and I'm fairly certain it was due to the cables becoming ever so slightly loose. Even if you think it's secure/snug, the only thing that has worked for me is a purpose-specific bracket that holds it in place.

As far as updating and this error goes, yea...I ran into the same issue. This was supposedly a bug in one of their firmware versions (I think .7 or something?). I went back and forth with Tazer...and while they were helpful, I can't even tell you what the actual "fix" was. It basically just "started working": https://www.jeepgladiatorforum.com/forum/threads/tazer-mini-firmware-borked.101534/#post-1629286

I can say it was a combination of:
* Having the right cable
* Using a Windows PC (and I think there's some setting to make sure USB connections don't get restricted?)
* Using the right port (you never know...the ports on your case going to headers on the motherboard could cause issues)

It really just came down to being very patient, and sometimes letting it sit for 10-20 minutes (e.g. when writing the firmware) even if it doesn't seem like there's any activity.

tl;dr this error sucks, and I initially lost a little confidence, but Tazer was responsive and I can't imagine how equally frustrating it must be trying to own and manage firmware that gets written remotely on devices.

It looks like it isn't connecting to the correct Com Port. Did you check device manager to see where it is connecting to?

This is your answer, It is not seeing it because you are not on the correct port for it to see it. I have been doing PCs for a long time. USB is plug and pray that it reads it correctly.

USB ports and COM ports are different

when I plug in the Tazer to my PC it’s calling the Tazer COM5.

So the app need to point to COM5. USB ports to communicate in apps use a virtual serial port

My Tazer works, fear to even touch it. Don't even want to check for updates.

I know this may sound dumb, but is the Tazer plugged into the SGW connectors BEFORE you try this?

Also, after that, make sure the usb is plugged into the Tazer BEFORE opening the app.

I had some similar issues when I first got mine, then I realized you have to be IN THE TRUCK and the Tazer plugged into the SGW connections BEFORE it will connect over USB, THEN the program SHOULD work.

If that doesn't work, uninstall the program. Fully shutdown the PC (it IS a PC and not a Mac, right?) Turn the PC back on, go to the Zauto site and download a fresh copy of their software, and install the fresh copy to your PCs HDD/SDD (not an external source like usb drive). Give it another go and let us know.

Hey there - just tried this. The Tazer blinks and shows its connected to the car, but the Jeep cant access the menu (from the correct RUN position). So i cant even get the Tazer menu to show up on the Jeep.

You had the "key" show "OFF" before connecting to SGW connectors, correct?

After that, you need the "key" showing "ON" but don't start the engine, then you have to scroll to page 7 (Audio page) and hold the Left Arrow while tapping the cancel button to scroll through Tazer menu.
- Did you do it this way?

Yes did this - Tazer Menu wont show up either on the jeep.

Did everyones suggestions. Still no progress - what a disappointment.

Turned off all antivirus/firewall etc. I'll see if I can get a 4th replacement.

Who and where are you buying these refurb models from?


I'd tell them that after 3 failed refurb models, they need to provide a discount on a new one for all the hassle.

That's just proper customer service and retention.
