Test DN: Step 13

13) Check EVR Circuit For Shorts to Power or Ground  With key off, breakout box installed, and ECA disconnected. Disconnect EVR solenoid. Set DVOM on 200-k/ohm scale. Measure resistance between test pin No. 33 and test pins No. 37 and 57, 40, 60, and 46 at breakout box. If any reading is less than 10 k/ohms, repair short circuit. Remove breakout box and reconnect all components. Repeat QUICK TEST. If code is repeated, replace ECA. If all readings are 10 k/ohms or more, replace ECA. Remove breakout box, and reconnect all components. Repeat QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 13) to step 20). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
