Clean those grounds!
I had an problem with the DIC resetting in the morning, evidence of a charging issue. When I went to hook up my ammeter, I discovered the bolt on the negative battery cable (that screws directly into the battery) was COVERED in chalky corrosion. I hadn't disconnected the battery in about two years, so if you haven't checked yours in that time, check it out before it leaves you stranded.
Even after cleaning and fully charging the battery, the BCM didn't want to sleep - pulling about 210ma. After PAINFULLY pulling each fuse & circuit breaker in turn (except the BCM fuses) I failed to discover the faulty circuit. By the way, repeatedly crawling into the passenger footwall to pull a fuse and then coming back out to check the meter is just GREAT for the back. </sarcasm>.
Back to the grounds - I started with the G101 ground - it looked ok, cleaned it anyway, reassembled, and glanced at the meter - 20ma. ASLEEP! I'm also hoping this will clear my intermittant C1214 EBCM error.
Moral of the story : CLEAN THOSE GROUNDS!
Cheers,
Barry

The ONLY grounds that are difficult to reach are the engine block grounds G105, 106 & 107. All the others can be serviced on the drive way.
