Test Equipment
CAUTION:
The following equipment is recommended to diagnose and test 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. See Equipment Hook-Up to ensure proper connections between test equipment and vehicle are made.
- Self-Test Automatic Read-Out (STAR) Tester with Adapter Cable. This tool is recommended, but not required. It is specially built for the EEC-IV system and is used to display, as numerals, the 2-digit service codes that are programmed into the control module. Adapter cable has LED assembly and plugs directly into vehicle self-test connector.
- Analog Volt/Ohmmeter (VOM) with 0-20V DC range. This can be used as an alternate to the STAR tester.
- Digital Volt/Ohmmeter (DVOM) with minimum 10 Meg-ohm input impedance.
- Breakout Box. This is a jumper wire assembly which connects between the vehicle harness and the ECA. The breakout box is REQUIRED to perform certain tests on the system. Ford Motor Co. specifically states that using the probe from a DVOM will cause PERMANENT DAMAGE to the 60-pin ECA connector. "Test Pin" as called out in Circuit Tests refers to the pins on the breakout box. Once the breakout box has been installed during a test sequence, it may be left connected for the remainder of the test.
- Vacuum gauge with 0-30 in. Hg range and resolution (unit on scale) of 1 in. Hg.
- Tachometer with 0-6000 RPM range, accuracy F 40 RPM, and a resolution of 20 RPM.
- Vacuum pump with 0-30 in. Hg range.
- Timing light.
- Spark tester. A modified spark plug with side electrode removed and alligator clip attached may be used.
- Fuel injection pressure gauge for all fuel injected models.
- Non-powered test light.
- Jumper wire about 15" long.
- MAP/BP Tester. Unit plugs into MAP/BP sensor circuit and DVOM to check input and output voltages to verify correct sensor operation.
