Task Manager: Notes

The Powertrain Control Module (PCM) is responsible for efficiently coordinating the operation of all the emissions related components. The PCM is also responsible for determining if the diagnostic systems are operating properly. The software designed to carry out these responsibilities is referred to as the "Task Manager". The Task Manager determines which tests happen when and which functions occur when. Many of the diagnostic steps required by OBD-II must be formed under specific operating conditions. The Task Manager software organizes and prioritizes the diagnostic procedures. The job of the Task Manager is to determine if conditions are appropriate for tests to be run, monitor the parameters for a trip for each test, and record the results of the test. The following are the responsibilities of the Task Manager software.
