the battery drain current should be below 100MA .. most it will be 50MA or less.. possible the BCM is always on .. some have had this because the BCM kept the radio on / amplifier etc.. then the glove box light or under hood lamp . fuses in the vehicle and under hood pull one at a time with meter setup ..digital meters are harder to show this compared to an analog meter that has a needle indicator .. you say .01 amps ??? or ??? .. clamp type meters do work better to get the most accurate current reading . other causes alternator disconnect the big wire ,, then any aftermarket electrical installed ...these can turn on unexpectedly... drain battery ....
