Test TC: Step 52

52) Checking TOT Signal For Short To Ground Turn key off and wait 10 seconds. Ensure bulkhead is disconnected at transmission. With breakout box installed and ECA disconnected, set DVOM on 200-k/ohm scale. Measure resistance between test pin No. 42 (test pin No. 7 on 7.3L diesel) and test pins No. 40, 46 and 60 at the breakout box. If all resistances are greater than 10 k/ohms, replace ECA and remove breakout box. Reconnect components and rerun QUICK TEST. If resistances are not greater than 10 k/ohms, repair short circuit, remove breakout box and reconnect components. Rerun QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 52) to step 90). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
