Test Fa: Step 14
14) Check NDS Circuit Continuity Between ECA & 4EAT Module With key off, disconnect 4EAT module 16-pin connector. Install breakout box leaving ECA disconnected. Set DVOM on 200-ohm scale. Measure resistance between test pin No. 30 and NDS pin at 4EAT module vehicle harness connector. If resistance is less than 5.0 ohms, EEC-IV system is not at fault, repair or replace transmission components as necessary. Remove breakout box and reconnect all components. If resistance is greater than 5 ohms, repair open circuit, remove breakout box and reconnect all components. Repeat QUICK TEST.
