Using Autel MS906BT Diagnostic Tool/Scanner?

[Badunit]

I thought I'd hook up my Autel MS906BT to my new 2023 Jeep today to see what it could do. Apparently not much without a special cable to the secure gateway module and an internet connection to authorize access through autoauth.com. I don't mind using a special cable but a diagnostic tool that requires internet access to work is kind of useless for me, plus I hear it requires an active Autel subscription ($700/yr !) to authorize and I'm planning on letting mine lapse. I am wondering if having a Tazer Mini hooked up would allow the tool to work through the OBD port and without any additional authorization or if there another way to use the full features of the tool (including live data, calibration/reset procedures, simulation of button presses, activating motors/solenoids, etc.) without needing authorization?

I am responding to my own thread nearly a year later. The Autel device is, as far as I can tell, useless on a 2023+ Jeep without an Autel subscription. An ECRI bypass device does not work with it nor does an Autel bypass cable (which did work while I still had a subscription). I don't have a Tazer but I am confident it will not work either. The Autel calls back to the Autel mothership for authorization and that's the end of it. I have read that it will quit working on any vehicle after a period of time after the subscription ends. JScan and ALFAOBD work fine, though both feel more like hacker tools than refined diagnostic apps.

I was told by Autel that their scanners will continue to work without updated subscriptions, but may not work with newer vehicles (newer than the updated subscription).

I hope so, at least for my other vehicles. What irks me is its need to call in to Autel via the internet to use it on my Gladiator. Now that my subscription has expired, when I try to use it on my Gladiator it just keeps telling me my subscription is expired. It is useless. I am bypassing the SGW so there is no need for it to contact Autel, no need to download or verify anything with them, and no need for a subscription. I sent a tech help email to Autel tonight. I wonder what they'll say.

Even when I had a subscription, its need to connect to Autel irked me. I work in place with a very poor wifi connection and it often failed to connect or would lose the connection part way through whatever it was doing. It didn't dawn on me until tonight to use my phone as a hotspot. Duh. It does not call in when used with any of my other vehicles, just the Gladiator.

Check this out from Autel

https://store.autel.com/blogs/news/...ion often leads to,and no software is removed.

Nice to have it in writing that it will continue to work for my other vehicles. With the Autel bypass cable it should have no need to connect with an Autel server (and no need for a subscription) with my Gladiator, but it does. I'm trying to get an answer from Autel about that.

 

[Badunit]

Autel confirms it will not work on my Jeep without a subscription. No reason for it other than $$. AlfOBD doesn't need to call in, JScan doesn't need to call in (other than confirming I have a license with them, which is a one-time forever license), but Autel bricks their device for my Jeep without a subscription. This is a warning to others who may want to buy a high-end diagnostic tool from Autel only to find out it costs a lot of money year after year after year to actually use it. Total BS.

I recently purchased a MaxiCheck MX808S for $403 from Amazon to troubleshoot my 2020 Jeep JLU, which has had a persistent "Stop/Start Unavailable - Service Stop/Start" message since the day I bought it. The dealer reset it a few times, but by the second year, both batteries died, causing a Christmas tree effect on my dashboard, and the car wouldn’t start without a jump from a friend. Luckily, it was still under warranty, so the dealer replaced the main battery. I insisted they check the auxiliary battery, which also failed, and both were finally replaced in 2022.

Now it's 2024, and my Jeep sat for months in a warm underground garage. A few weeks ago, I charged both batteries to 100% with a Battery Tender. However, my car failed to start at a stoplight, seemingly switching to the main battery, and the same "Stop/Start Unavailable - Service" message appeared again.

Fast forward, I connected my new Autel MX808S to the OBD2 port. After identifying my vehicle VIN, I received a message:

1. "For this model, please use the Chrysler 12+8 dedicated diagnostic connector; otherwise, not all functions like code clearing and motion testing will be available. Consult your local dealer for this connector."
2. "Refer to the picture and video help for the connection."

Then, I encountered the FCA Security Gateway Access message, prompting me to register/login to AutoAuth.com. I paid a $50 annual subscription fee to gain access to features like error code clearing, added my MX808S serial number to the AutoAuth portal, and successfully erased all fault codes.

Now, I’m confused about why the 12+8 split cable is necessary, costing about $15 on Amazon, and why registration with AutoAuth is required. Am I missing something without this cable? Also, it seems this device can’t control the BMS module of my Jeep, displaying the error "Selected function not supported." I’m feeling lost and unsure if it's worth keeping this unit since I’ll need to pay a $125 Autel subscription fee and a $50 AutoAuth fee annually just to reset battery messages when they drop below the threshold. Any advice or insight would be appreciated!

I've only used the bypass cable and, more recently, the ECRI bypass. With the cable or ECRI you don't need the Auto Auth subscription.

With an Auto Auth subscription you do not bypass the SGW. I believe you use the built-in OBD port under the dash with the SGW hooked up like it is supposed to be, but I have never gone that way. With the Autel bypass cable you do not need an Auto Auth subscription. You disconnect the SGW (which is a total pain in the butt), plug in the cable, and use the OBD port on the cable. But Autel apparently requires their own subscription either way, which is total money grubbing when the SGW is bypassed. JScan and ALFAOBD work without an Auto Auth subscription and my Autel unit did too until my Autel subscription ran out. It could work if they wanted it to but they wouldn't get a continuing revenue stream that way. I am going to take every opportunity available to point this out so others don't get unpleasantly surprised like I did.

The ECRI bypass device is like the bypass cable except it lets you connect to the built-in OBD port. If I was to leave the SGW bypassed, this is more convenient than the bypass cable.

If you decide to use the bypass cable or ECRI bypass after your Auto Auth license expires, you'll want to buy an SGW extension cable so you only have to disconnect the SGW one time in your life. You can put the disconnection point somewhere you can actually get your fingers to.

I just want to confirm how the SGW cable setup works. If I connect the SGW bypass cable like that https://a.co/d/1B49z2F to the 8+12 pin ports that run cables to a "secure module box," and then connect that box to my OBD port, does this mean that connecting the 8+12 cable effectively disables my original OBD port, turning it into a dummy? Would the other end of this 8+12 cable serve as my new bypassed OBD2 port for my Autel device? Can i keep this https://a.co/d/1B49z2F cable permanently attached while driving and not using Autel like devices ?

Additionally, I’m curious about how this setup works with an ERCi scenario. Should I buy this specific box? https://ecri.app/products/ecri-security-module-bypass-2018-jeep-ram , does it just block my OBD port? How would I connect my Autel device in this case?

It also seems like my Autel device might become useless in 12 months, given my experience so far. I was hoping to gain access to battery management systems (BMS) , but my Autel device keeps telling me “selected function is not supported.” Many features in the Autel interface for my Jeep, like testing door switches, seem unavailable. Am I missing something, or is this a limitation of the device?

I also noticed some discussions about different SGW cable options here, and the Autel 8+12 cable looks different.

Here are some recommended SGW bypasses from www.alfaobd.com

- [Z Automotive Double Bypass](https://www.zautomotive.com/product/z_dbp/) - For 2018+ Dodge/Chrysler/Jeep vehicles.
- [Z Automotive SGW Bypass](https://www.zautomotive.com/product/z_sgw/) - For all Stellantis (FCA) vehicles, including Alfa Romeo and Fiat platforms with the second High-Speed CAN bus (Alfa Romeo Giulia/Stelvio, Fiat 500X/Toro/Jeep Renegade/Compass MP).
- [KAOD Tech Security Module Bypass](https://www.kaodtech.com/product-page/security-module-bypass) - For RAM/Dodge/Jeep vehicles.
- [ECRI Security Module Bypass](https://ecri.app/products/ecri-security-module-bypass-2018-jeep-ram) - For 2018+ Jeep/RAM vehicles.



Which cable might work best with my Autel setup? I’m particularly concerned about compatibility and ensuring full access to all diagnostics features?

Thanks !

I bought a bypass cable at the recommendation of alfaobd, but with my Tazer connected it's not necessary (2022). The Tazer does the gateway bypass and everything works on the Autel as best I can tell. I've only read various information, haven't tried to change anything but I haven't seen any errors.
