Powertrain Control Module
The center of the Electronic EC system is a microprocessor called the powertrain control module (PCM). The PCM receives input from sensors and other electronic components (switches, relays). Based on information received and programmed into its memory, the PCM generates output signals to control various relays, solenoids and actuators. There are several different types of PCM's in use for this model year. Refer to the vehicle PCM application table below for PCM type and their applications.
