The PSCM determines all operating modes for the PTBA system, it contains control for the powertrain speed requests, brake requests, trailer curvature control (through steering wheel position), trailer angle offset calibration and jacknife protection and limits. The PSCM also sends out requests to the IPC and centerstack infotainment display indicating the appropriate message to be displayed for the operating condition.
