Test KE: Step 7

7) Check ISC Circuit Continuity  Turn key off and wait 10 seconds. Leave ISC solenoid disconnected. Disconnect ECA 60-pin connector. Inspect connector for damaged pins, corrosion, or loose wires. Repair if necessary. Install breakout box, leaving ECA disconnected. With DVOM on 200-ohm scale, measure resistance between test pin No. 21 and ISC circuit at ISC vehicle harness connector. If reading is greater than 5 ohms, repair open circuit, remove breakout box and reconnect all components. Repeat QUICK TEST. If reading is less than 5 ohms, go to next step.
