Chrysler 12+8 Bypass Cable, Star Connector or AutoAuth?

Question before entering:

I’m trying to clear codes on a 2018 Journey. I paid for the AutoAuthority subscription and registered my Autel MaxiSys Elite on AutoAuth website.
I do have the Autel 12+8 bypass cable so I can bypass the SGM.
Once I registered the Elite on AutoAuth that I would no longer need the 12+8?

 

Suggestion:

Beginning in 2018, FCA began manufacturing vehicles with a Security Gateway Module (SGM) that blocked direct communication to and through the OBD2 port to the vehicle, effectively limiting communications to basic diagnostics. It also effectively isolated the CAN bus from being directly penetrable by aftermarket diagnostics and programming tools.

Fortunately, people much smarter and have figured out the CAN (Controller Area Network) lines of the vehicle can be intercepted after a point where communication is typically blocked by the SGM. Alternatively, the SGM can be bypassed entirely. The benefit of the CAN method is that you often have multiple access points because of the structure of the CAN bus architecture.

Common bypass methods are Autel 12+8 bypass cable, Star connector, AD cable and AutoAuth subscription.

 

 

Autel 12+8 Cable:

This adapter will be required when accessing a Fiat Chrysler Dodge and Jeep vehicle that uses a Secure Gateway Module.

Code scans don’t require the 12+8 only if you need to erase or do but-directional

Review and success rate:

1. found the sgw module it was further up under the dash, had to remove the lower cover. The cable worked like a charm once I found the module.

2. i use mine regularly, most impressive was i needed it to scan a Maserati suv.

3. Just used my MS906TS on a 2018 Ram today. Worked flawlessly. I won’t have to use my Micropod II for quick stuff anymore. And won’t have to pay Tech Authority every time.

4.  12+ 8 is the best cable for a few random reasons. I use it quite often when I can’t get signal for Witech.

5. diagnostic scan on a 2018 Dodge Durango. Autel MS906TS with the Chrysler 12+8 adapter.

6. 2019 dodge challenger all keys lost…..Job Done by im608 and 12 +8 cable.

 

AutoAuth 

There is a newer service called Auto Auth.  With the newest update on your Autel android-based tool (i,e Autel MaxiSYS 908P / MS906, Autel MaxiIM IM608 etc) you now have access to the security gateway module on 2018 and newer Fiat Chrysler vehicles in North America, so that the tool can clear codes, bi-directional function, active tests, actuations and relearns. Autel has made this process very simple to access with three simple steps: authorize, confirm and access.
