Test Aa: Step 4

4) Check Ignition Ground Continuity  Turn key off, wait 10 seconds. Disconnect and inspect ECA 60-pin connector. Install breakout box, leaving ECA disconnected. Disconnect EDIS module. Set DVOM on 200-ohm scale. Measure resistance between test pin No. 16 at breakout box and IGN GND circuit at EDIS module vehicle harness connector. If resistance is more than 5 ohms, repair open in circuit and repeat QUICK TEST. If reading is less than 5 ohms, go to next step.
