Test B: Step 4

4) Check Continuity of SIG RTN Circuit  With breakout box installed and ECA connected, turn key off and wait 10 seconds. Set DVOM on 200-ohm scale. Measure resistance between test pin No. 46 at breakout box and SIG RTN circuit at the Self-Test connector. If resistance is greater than 5 ohms, repair open in SIG RTN circuit. Remove breakout box, reconnect components and repeat QUICK TEST. If reading is less than 5 ohms, remove breakout box, connect ECA and go to next step.
