2003 SL55 SRS Light always on...NO Code! HELP!
Hello All,
I have an issue with the SRS warning light on the dash being on always, and no code is found with my scanners (Foxwell NT530, and iCarsoft MBII). Fuse is good. but since there is no code, there is nothing to erase, and I can't figure out for the life of me why the light is on.
I DO know this is not good, since it likely means the system is inactive. Can anyone lead me in the right direction in order to fix this? Thanks in advance.

I have occasional SRS when the passenger seat is unoccupied and it is from an intermittent fault on the rear facing baby seat sensor. I understand it is a very common issue where wires in the sensor break. You'll need a better scanner to know for sure what the problem is.

I had the same issue. Mine was a slightly loose connection under one of the seats. It's a yellow plug you can check in the front of the seats. Once I connected that properly I disconnected the consumer battery for 30 minutes. When the battery was reconnected the error was gone.its worth a try.

To All,
Thanks so much for the suggestions. As it turns out, I found the yellow connector (rectangular, 6 pin) was being pulled very tightly with the seat all the way back, where I normally have it set. I gave it some slack, and scanned the system again with a icarsoft MB II scanner. For some reason, I finally got a code B1864 002 that I could clear. I cleared the code, and the light went out.
My previous issue was that I couldn't get the scanner to generate a code, so I couldn't clear the SRS light.
Tomorrow it's ABC system accumulator replacement time along with a system flush. I will take pics and post later.
