12+8 Adapter for FCA Chrysler Dodge Secure Gateway Module Bypass
The 12+8 Adapter is used to bypass FCA Vehicles 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, Dodge, Jeep, Fiat, or Alfa vehicle 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 sidekick panel, passenger side near the glove box, or behind the radio.
The 12+8 Adapter connects to the Autel MaxiSys VCI.
