Once one of my friends called me that his Jaguar had dead battery recent. He must charge it every 3 or 4 day to keep it work. I checked its battery current draw and found it was 138 mA when it should be less than 50 mA. I doubted some electronic control module didn\'t go to sleep mode at that time. I noticed that the seat belt at passenger side didn\'t work. I called him back and asked what had he done with his car. He told me the seat belt buckle was broken and he pulled out its fuse. Why, I asked. He said he hated the belt moved up and down when he start and shut off the engine. It is automatic controlled seat belt. I realized at that time the body control module could not go to sleep mode if the seat belt buckle couldn\'t be at the release position ( down position ). I put the fuse back and checked the current draw again, it was 28 mA.
