#912 of 914 Re: 2005 Dead battery Syndrome [immoe] by saholz Aug 30, 2008 (8:46 am)
Replying to: immoe (Aug 30, 2008 8:05 am) DBS is directly related to the requirement that all 2005 manual transmission cars must be placed in reverse for a proper shutdown of the electronics. Assuming that you always shift to reverse when shutting down, DBS refers to an unexplained battery drain on properly shut down cars, and typically occurs within 48 hours of the car being turned off.   If this is the cause of your problems, rather than just a weak battery, GM has issued a TSB that calls for a reflash of the BCM, or Body Control Module. This reflash has been completely successful in addressing the problem. I don't have the TSB # handy, but any dealer should be able to find it in their computer database.

Replying to: immoe (Aug 30, 2008 8:05 am) And, with a 3-4 year old battery, it might just be time for a new battery. The battery in these things is small, only 550 or so CCA, which the cheapest battery at Walmart can beat, and the car has a lot of electronics in it. For the low milage you stated, you cannot be driving the car regularly enough to recharge a battery.   But given all of the above, yes, there is a TSB on reflashing the logic in one of the car's computers. This should be done no matter what.   It's a shame if your dealer is not really wanting to help you here. This is a very well known problem, and a dealership servicing any amount of 2005 manual cars should know about this. And even if the car is out of warranty, the dealer should be willing to do this for your car.
