Sorry for the delay...
Is this 500 to 600 millamps draw after sitting at least 20 minutes?
The computers need time to go to sleep. After 20 minutes or so you should see around 35 milliamps...
Keep me posted...
Thank you,

This would be after the car has been sitting for over an hour.(600 mAmp draw) Something is draining the battery overnight. What could cause this problem. No lights on even checked glove compartment.
Expert:  Robert replied 2 years ago.
There are several things that can cause this. It could be anything from like you stated about a light being on, it could be that one of the modules won't go to sleep keeping the BUS awake or an aftermarket accessory installed that is interfering with the onboard electrical system..
At this time, I recommend to start disconnecting fuses one at a time to see if you can isolate the problem to a given circuit.... try this and let me know which fuse number drops the draw within range....
Keep me posted...
Thank you,
