    2. OBJECTIVES After studying Chapter 11, the reader will be able to: Prepare for ASE Electrical/Electronic Systems (A6) certification test content area �A� (General Electrical/Electronic Systems Diagnosis). Explain the purpose and function of onboard computers. List the various parts of an automotive computer. List five input sensors. List four devices controlled by the computer (output devices).

    3. COMPUTER CONTROL Modern automotive control systems consist of a network of electronic sensors, actuators, and computer modules designed to regulate the powertrain and vehicle support systems. The powertrain control module (PCM) is the heart of this system. It coordinates engine and transmission operation, processes data, maintains communications, and makes the control decisions needed to keep the vehicle operating.
