Test TC: Step 20

20) Checking E4OD Transmission Solenoid Resistance  Turn key off and wait 10 seconds. Disconnect ECA 60-pin connector and inspect for corroded or damaged pins. Service or repair as necessary. Install breakout box, leave ECA disconnected. Connect transmission bulkhead connector. Set DVOM on 200-ohm scale. Measure resistance between test pins No. 37 and 57 and ECA signal test pin at the breakout box (see step 12). If resistance is within specification, go to step 17). See SOLENOID RESISTANCE CHART. If resistance is not as specified, go to next step.
