on the 2006 sl500 , you will need the star system or equivalent to clear & register new battery.

as long no fuse were blown and you said you checked .

unfortunately the auto start scanner is limited only can do engine codes and maybe abs codes, but want be able to communicate with your battery module .

Let me know if you need anything else on it , just reply back here & we can continue.

if you are good , Please Kindly rate me.

Hope I was helpful to you

A 5 Star Positive Rating is Much Apreciated
