Vehicle System Controller (VSC)

The PCM, the TCM and the BECM are connected to a high speed controller area network (CAN) to exchange information messages. The VSC is a software function integrated inside the TCM, and is responsible for vehicle system operation, generating and sending commands to initiate appropriate actions such as LOS modes when concern is detected. The TCM also stores DTCs along with the freeze frame PID related to the LOS action that was initiated.
