The engine management system consists of the
Powertrain Control Module (PCM), and numerous
inputs and outputs. The PCM has an internal Engine
Control Module (ECM) and a Transmission Control
Module (TCM). Both modules share inputs, process
analog and digital signals, and communicate internally
with each other through the Controller Area Network (CAN).
