WHAT SHOULD THE AMPERAGE DRAW BE ON THE ECU ON THIS CAROLLA?

I bought an older 1992 Corolla for my son as he is starting to drive. After a week of sitting the battery was dead. Checked the bat 10.5 volts replaced it. Parasitic draw test showed a 4.26 amp draw with every thing off. After some time I traced it down to the ECU. Pulled the fuse amperage draw drop to 0 amps. What then is a proper draw for the ECU? Could the draw be passing through the ecu by another sensor. Looking at the schematic it looks like it is not an easy job checking all the resistence in every circuit.
I could not find anything in my Alldata DIY account?
