Powertrain Control Module (Pcm)

Powertrain Control Module (PCM) receives cruise control related inputs from Vehicle Speed Sensor (VSS) and Clutch Pedal Position (CPP) switch. Using these inputs and inputs from Throttle Actuator Control (TAC) module through serial data network, PCM determines whether to enable or inhibit cruise function.
