Test TC: Step 21

21) Checking Continuity Of E4OD Solenoid Harness  Turn key off and wait 10 seconds. Install breakout box, leaving ECA disconnected. Disconnect transmission bulkhead connector. Set DVOM on 200-ohm scale. Measure resistance between the ECA signal test pin at the breakout box and transmission bulkhead connector (see step 12). Measure resistance between test pins No. 37 and 57 (test pin No. 35 on 7.3L diesel) at the breakout box and EPCPWR and VPWR pins at the E4OD transmission bulkhead connector (refer to circuit diagram at start of test). If all resistances are less than 5 ohms, go to next step. If resistance is greater than 5 ohms, remove breakout box, repair open circuit and reconnect ECA and solenoids. Rerun QUICK TEST.
