TROUBLE SHOOTING FORD'S MICROCOMPUTER CONTROL UNIT, PART 2

Part 1 of this 2-part article outlined which engines have the microcomputer control unit (MCU) and contained a chart listing its parts. This chart is necessary to perform the diagnostic tests explained in the present article. The purpose of troubleshooting the MCU is to determine if a part of the system is causing poor engine performance. To do so, one of two instruments is needed: the Self-Test Automatic Readout (STAR) unit, or an analog voltmeter. This article reviews how to use both instruments in 2.3-liter engines, 4.9-liter engines and V8 engines.
