Powerless battery over night! STS 1995

[rockfangd]

My 2001 DTS battery kept draining for no apparent reason several months ago. The dealer checked everything possiable and the Delco battery was only 5 months ago.Someone on this board said their was a TSB but I was unable to find it. I took a shot and had them replace something called a Rear Intergration Module with a costs to me of about $400 including labor. It was a real shot in the dark something that I do not like to do. I have let the car sit in my storage garage for 4 weeks on several ocasions and have not had a dead battery since the RIM was replaceed. I am not suggesting you replace it but wanted to share my experience.

Good Luck

You hit the nail on the head with the RIM. and I am nearly certain there was a TSB on that. They do weird things when they start to go.

Using an ammeter and pulling the fuses until the parasitic draw goes below 30 mA would easily

Using an ammeter in series with the negative battery cable and pulling the fuses until the parasitic draw went below 30 mA would easily isolated the draw to the circuit the RIM was on. Then it would have been a matter of systematically disconnecting modules on the circuit until the parasitic draw went below 30 mA. The problem is that a lot of dealers are too lazy to do proper troubleshooting and would rather throw expensive parts at the problem at the owner's expense.

As info my dealer was completely against replacing the RIM. he had the car for 3 days because I insisted they run the parasite draw for a extended period of time. The Tech also used the disconnecting of the modules. Well I agreed to pay and twisted some arms since they did not want my money. Someone on this board posted the RIM and the TSB so I took a shot and corrected the problem.
