Selected 2018 models contain new module called Security Gateway (SGW). This module isolates vehicle CAN-BUS, infotainment (radio) CAN-BUS and diagnostic link connector CAN-BUS (OBD-II). It also prevents aftermarket scantools such as Autocom and Autel to perform any active diagnostic routines such as clearing fault codes, perform actuators, ECU programming, etc.
The only tool capable of diagnostics via OBD-II is the dealer tool, which authenticates bi-directionaly the gateway using strong cryptography algorithms.
