How A Car Computer Works?
Computer PCM/ECM/BCM Working Of Vehicles Computer System Powertrain control module / Engine control module / Body control module Helpful Information Communication standards were established in the OBD2 operating system development. These communication standards used a CAN (controller area network) system which can achieve communication speeds of more than 500 Kbps. Advantages of using information buses for communication is that if a fault occurs with any of the process modules, it can be reported separately to a diagnostic tool. Wiring is simplified by a technique known as multiplexing, a kind of wiring system which is assigned for each module. Sensor circuits operate on a 5 volt reference which drive system monitoring and control. This article explains how an automotive computer PCM (powertrain control module) works. A car computer or powertrain control module (PCM) is a designated computer that was developed to manage the engine and driveline components. This ...
