Test A: Step 7

7) Check SPOUT Signal  With KOEO, install breakout box and connect ECA. Move breakout box timing switch to COMPUTED position. Set DVOM on 20-volt scale and measure voltage between test pin No. 36 at the breakout box and battery negative post while cranking engine. If voltage is between 3 and 6 volts, EEC system is NOT at fault. Diagnose TFI or DIS ignition system. If voltage is less than 3 volts or more than 6 volts, go to next step.
