Test Ff: Step 2

2) Check Continuity of PSPS Circuits  Turn key off and wait 10 seconds. Disconnect PSPS and ECA 60-pin connector. Inspect for and repair any damaged wiring. Install breakout box, leaving ECA disconnected. Set DVOM on 200-ohm scale and measure resistance between test pin No. 46 and SIG RTN circuit at the PSPS vehicle harness connector. If both readings are less than 5 ohms, replace ECA. Remove breakout box, reconnect all components and repeat QUICK TEST. If readings are greater than 5 ohms, repair open in circuit. Remove breakout box, reconnect all components and repeat QUICK TEST.
