Measure resistance between test pins No. 30 and 46. If resistance is greater than 10 k/ohms, for vehicles with A/C go to step 10). For all other vehicles, replace ECA, remove breakout box and repeat QUICK TEST. If resistance is not greater than 10 k/ohms, repair short circuit, remove breakout box and reconnect ECA. Repeat QUICK TEST.
