Test TC: Step 23

23) Checking E4OD Solenoid Harness For Short To Power  Turn key off and wait 10 seconds. Install breakout box, leaving ECA disconnected. Ensure transmission bulkhead connector is disconnected. Set DVOM on 200-k/ohm scale. Measure resistance between ECA signal test pin (see table in step 12) ) and test pins No. 37 and 57 at breakout box. If all resistances are greater than 10 k/ohms, go to next step. If resistances are less than 10 k/ohmns, repair short circuit(s), remove breakout box, reconnect ECA and solenoid(s). Rerun QUICK TEST.
