Test Equipment

The following equipment is recommended to perform the Quick Tests and Pinpoint Tests on EEC-IV systems. Some equipment is REQUIRED to perform tests. DO NOT  attempt to test this system without proper equipment. Damage to vehicle components will result if improper equipment is used.

• Self-Test Automatic Read-Out (STAR) Tester. This tool is recommended, but not required. It is specially built for the EEC-IV system and is used to display the two digit service codes that are programmed into the control module.
• Analog Volt-Ohmmeter with 0-20V DC range. This can be used as an alternate to the STAR tester.
• Jumper wire about 15" long.
• Vacuum Gauge with 0-30 in. Hg range, and resolution in the 1 In. Hg. range.
• Tachometer with 0-6000 RPM range, accuracy plus/minus 40 RPM and resolution within 20 RPM.
• Vacuum Pump with 0-25 in. Hg range.
• Digital Volt-Ohmmeter (DVOM) with 10 megaohm minimum input impedance.
• Timing light.
• Spark tester. A modified spark plug with side electrode removed and alligator clip attached may be used.
• Breakout Box. This is a jumper wire assembly which connects between the vehicle harness and the processor assembly. The Breakout Box is REQUIRED to perform certain tests on the processor. Ford Motor Co. DOES NOT recommend using a DVOM to probe the processor pin connector as permanent damage to the pins will result.
