electric power consumption during overnight parking?

[Enjoyneering]

Hi everyone,

I need a community help. Almost a year ago I had battery drain problem and now it happen again, but this time I don't have any error codes. So I'm not 100% sure is it electric issue or just a dead battery.

Just after I've pressed lock button the drain current is about 2Amps and during next minute or two it slowly goes down to 0.2Amp. I seams to me that 0.2Amp is a little bit high, because my Kia drains about 0.001Amp after alarm goes on.

Can somebody measure 2009 Aveo5 drain current and post it here? Thank you in advance.

Tracker unit or faulty radio remembering pre set stations?

Thank you DuncanG.

Only standard useless OnStar tracker (it has it's own 16v Lithium-ion battery under front passenger seat) . I've disconnected lithium - no difference. Drain current is the same - 0.2Amps. Does anybody know where is OnStar module located?

Radio is acting normal. It saves and restores station, volume level and ect like it should.

Maybe 0.2Amp is normal for 2009 Aveo5? Maybe it's a dead battery? Can somebody measure 2009 Aveo5 drain current and post it here? Thank you in advance.

Try pulling the OBD fuse and check to see if that reduces the draw.

You think that MCU dosen't go to sleep?

I agree. Start pulling fuses to see what is drawing power. 200mA does seem on the high side.

That's the fuse which protects the Onstar circuit.

OK, thank you all. I'll do today.

Hi All,

I've localize the problem - it's the dashboard. When I pull out cluster/room fuse the current dropped to 0.003Amp. Now I need to fix it. Going to do it on weekend. Will keep you informed.

Thank you all.

P.S. OnStar tracker located under the driver seat.

Great job. Please let us know how it goes.
