Normal Operation and Fault Conditions
The SCMG communicates with the diagnostic scan tool through the MS-CAN. Diagnostic messages are sent/received between the DLC and the diagnostic scan tool through the HS-CAN2 circuits at the DLC, and are translated through the GWM to the MS-CAN.
The multi-contour seat relay is integral to the BJB.
