After doing some checks, I've found that the Renix ECU and TCU each draw a constant 6ma of current, with the key off. This appears to be normal for the Renix, but if the vehicle is not driven for a couple of weeks, it'll drain the battery noticiably.
I'm trying to switch the ECU off when the XJ isn't driven for several days, because of the steady 12ma current draw. I figure the easiest way is to place a toggle switch between the ECU and engine ground. I've disconnected all the ground wires that are apparent, including the wires connected with the battery ground cable on the block, and still have the current draw.
My question is: Where does the ground circuit to the ECU (and TCU) terminate?
Thanks for any help on this.
