2007 Yaris Battery Drain

Recently developed battery drain on 2007 Yaris hatchback. Took it to a mechanic who said radio was the culprit. Had him unhook radio and would pick up next day. Next day mechanic calls and says computer is also causing a parasitic drain and they don't deal with that. Not a Toyota dealer. Called Toyota dealer. $1000.00 plus labor for new computer. Picked up the car and drove it home. Car ran fine shifted fine acted fine except for one thing which was happening before taking to mechanic. Couldn't lock doors. Tried locking from inside with buttons but would unlock as soon as I shut doors. Manually locked but would unlock as soon as door shut. No key fob. Maybe unrelated to drain. Tried checking drain myself with 12 volt light. Got a dim pulsing light. Pulled ecu-b fuse and light went off. Of course car won't start or run without. Haven't checked any further yet until I get a meter. Hope someone can help me with this problem. Thank you.
