Description:
Since the Fiat Chrysler Group (FCA)-related models in 2018 or later are equipped with the Security Gateway Module (SGM/SGW), this module isolates most diagnostic requests for all post-market diagnostic devices except the original one through a powerful encryption algorithm. Such as clearing fault codes, motion tests and ECU programming.
For FCA models in 2018 or later, non-original equipment can only be used to read fault codes, vehicle VIN identification, and view data streams through the OBD diagnostics station.
In response to this problem, the isolation of the SGM/SGW can now be bypassed by the FCA 12+8 dedicated conversion diagnostic connector.
The 12+8 Adapter is Autel's bypass for Chrysler's Security Gateway Module (SGM) which limits an aftermarket scan tool to only reading DTCs and viewing data.
Most 2018 and newer FCA vehicles include a Security Gateway Module.
If you don't use AutoAuth you can expect to see this message when scanning a Chrysler with the Security Gateway Module:
DEVICE UNABLE TO COMMUNICATE WITH THE CONTROL UNIT
Placement of the SGM varies, but it is often located in the side kick panel, passenger side near the glove box, or behind the radio.
Function:
1.OBD instrument mileage calibration, OBD anti-theft matching, etc.
2.Used with other diagnostic devices to read and clear fault code.
The Cable Adapter can be used with Autel scanners, such as MS906, MS906BT, MS906TS, MS908, MS908S, MS908S PRO, Maxisys Elite, IM608, IM508 etc.
Connection Method:
1.Locate and unplug the 12pin and 8PIN connectors of the SGW module.
2.Then connect the FCA 12+8 directly to the 12pin and 8pin (two connectors connected to the SGW) connector on the car.
3.At this point, normal communication with the car can be achieved.
