I have trouble shot this car a lot. I have a DC ammeter, and when I turn the car off I watch the current drain go down in stages, as it should, and it generally goes to a very low millamp level. I firmly believe, at this point, that sometimes, intermittently, that something in the car does not turn off properly and the current drain stays high and runs the battery down. Or, if everything does turn off properly, that sometimes during the night something turns back on. I just don't know.
1. I may have to get a permanently installed DC ammeter with a data storage device, so that I can see a log of current drain over times, such as hours/days. Anyone done that?
2. Where is the BCM located on my car: 2006 DTS? Thanks!
3. Any help, suggestions?
Later,
Raymond
This is looking at the back of your dashboard from the front of the car.
Although it's been a while now, and there is not been another "no start" issue, I'm still keeping my fingers crossed that an intermittent problem still doesn't crop back up. But after learning how the charging works on this model car, i fell pretty confident.
So i think ive solved a alot of issues in one swipe here. I may be mistaking but go to your control modules and pull out the plugs and check your crimped connections. I think thats probably the culprit with most of the issues here. I just found the supply line to a preciously untouched rim modile to be loose enough where you could roll it back and forth in the crimp itself and that will cause so many issues.
Poorly crimped connections can lead to a variety of issues, such as an electrical short, an open circuit, or a weak connection. Poor quality crimps can cause corrosion, intermittent or poor performance of the connection, and even complete failure of the connection.
