Test QD: Step 2

2) Check CASE GND Circuit Continuity  Turn key off. Disconnect ECA 60-pin connector. Inspect connector for damaged pins, corrosion, or loose wires. Repair if necessary. Install breakout box, leaving ECA disconnected. Set DVOM on 200-ohm scale. Measure resistance between Test Pin No. 20 and chassis ground. If reading is less than 5 ohms, go to next step. If not, repair wiring harness. Remove breakout box, reconnect components and repeat QUICK TEST.
