Powertrain Control Module (PCM)
The powertrain control module (PCM) is located in the passenger compartment below the center console. The PCM controls the following:
- Fuel metering system.
- Ignition timing.
- On-board diagnostics for powertrain functions.
- Automatic Transmission Control System
The PCM constantly observes the information from various sensors. The PCM controls the systems that affect vehicle performance. The PCM performs the diagnostic function of the system. It can recognize operational problems, alert the driver through the Check Engine lamp, and store diagnostic trouble codes (DTCs). DTCs identify the problem areas to aid the technician in making repairs.
