Test TC: Step 41

41) Check Continuity Of TOT SIGNAL And SIGNAL RETURN Circuit Turn key off and wait 10 seconds. Ensure bulkhead connector is disconnected at transmission. Disconnect ECA 60-pin connector and inspect for corroded or damaged pins. Service or repair as necessary. Install breakout box, leave ECA disconnected. Set DVOM on 200-ohm scale. Measure resistance between TOT SIGNAL at the bulkhead connector and test pin No. 42 (test pin No. 7 on 7.3L diesel) at the breakout box. Measure the resistance between SIGNAL RETURN at the bulkhead connector and test pin 46 at the breakout box. If both resistances are less than 5 ohms, replace ECA, remove breakout box, reconnect ECA and bulkhead connector. Rerun QUICK TEST. If resistances are not less than 5 ohms, repair open circuits, remove breakout box and reconnect ECA. Rerun QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 41) to step 50). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
