Computerized Engine Controls: Notes

The 6.5L Diesel engine (with or without turbocharger) uses a Powertrain Control Module (PCM). The system consists of a PCM, input devices and output signals. PCM electronically controls fuel flow, fuel timing advance/retard, idle speed, EGR system operation, cruise control, Torque Converter Clutch (TCC) engagement, transmission shifts and glow plug system.
