Test Fa: Step 6

6) Check Neutral Gear/Clutch Harness  With key off, set DVOM on 200-ohm scale. Install breakout box, leaving ECA disconnected. Disconnect vehicle harness at NGS and CS. Measure resistance between test pin No. 30 and NGS harness connector. Measure resistance between test pin No. 30 and CS harness connector. Measure resistance between test pin No. 46 and NGS harness connector. Measure resistance between test pin No. 46 and CS harness connector. If each resistance is less than 5 ohms, for vehicles with A/C, go to step 10). For all others, replace ECA. If resistance is not less than 5 ohms, repair open circuit, remove breakout box, reconnect all components and repeat QUICK TEST.
