Powertrain Control Module

There are a large number of components responsible for controlling vehicle emissions. It is the job of the Powertrain Control Module (PCM) to coordinate their operation and keep them functioning in the most efficient manner possible. The PCM is also responsible for determining if the systems are operating properly. A new piece of software, designed specifically for this Job, is the "Task Manager."
