WARNING: This page is about a different car, the 2015 RAM ProMaster 3500, 2015 RAM ProMaster 2500, and 2015 RAM ProMaster 1500. However, it is still accessible from the selected car via links, so may be relevant.
The Powertrain Control Module (PCM) is located next to the Power Distribution Center (PDC). The PCM is a digital computer containing a microcontroller. The PCM receives input signals from various switches and sensors that are referred to as PCM Inputs. Based on these inputs, the PCM adjusts various engine and vehicle operations through devices that are referred to as PCM Outputs.
The PCM uses the CAN-C bus to perform engine diagnostics and flash operations.
