Strange electrical problem with my '00 300M

May 09, 2013 1 Replies

So this morning I start my 300m for my 1.2 km commute to work. Car starts and idles just fine. I put it in reverse and back out of garage.



I notice that the (ABS) light is on, and so is "Trac Off" light.



Hmmm. Ok.



I continue my drive to work - car seems to run just fine. Those lights stay on.



I get to my office, park, turn car off. The factory in-dash CD player blinks it's lights several times.



Hmmm. I remember it did that back a couple years ago when I still had the factory-original battery in the car, and the battery capacity was pretty much worn out, and the CD player would blink it's lights occassionally after starting the engine.



So I just leave the car as-is and go on with my day. A few hours later I decide to see if there are any codes to display. I do the key-on/key-off thing 3 times, and I get only 1 code: P-1684.



Basically, a code that just says that the battery has been disconnected within the last 50 starts.



????



So a few hours later when I leave my office, I start the car, it starts fine, no codes, no warning lights, and I drive home, no issues, turn off the engine, the CD player does nothing.



Any ideas???


Corroded battery connections? Bad ground ?
