The powertrain control module (PCM) is designed to maintain exhaust emission levels while maintaining excellent driveability and fuel efficiency. The PCM controls the following operations:
- The fuel control
- The ignition control (IC)
- The knock sensor (KS) system
- The automatic transmission shift functions
- The manual transmission
- The cruise control enable, if so equipped
- The generator
