“Sos inoperative” anyone change a teleaid module?
brought my car to the dealer for a wheel change...
service advisor tells me my battery has drained completely dead.
a new battery installed, now the sos inoperative light comes on and cant be deleted via code scanner.
is this usually a software update needed? Car is 4 yrs old, 2014, and never had this issue before.
or should i just replace the module, does a module need programming when install (used or new?)

Try this. I found it in the archives. It appears your battery replacement may have triggered the warning. Worth a shot at least.
To turn off the SOS warning, shut off the engine and then turn the key back on. Then turn on the headlights and leave them on for two minutes. Then turn them off and turn off the key. The message may still there at the time but will be gone the next morning. It has to do with the brain box having a battery voltage question and by burning the headlights for two minutes, the brain box sees a voltage drop and records the new battery voltage.

Did they say what is wrong with the module? If you don't use the TELEAID system, you can code it out of the central gateway. I have done for many of my customers. I just did it on my 2011 E350, it kept on setting a code for antenna connection so I just told the central gateway that it didn't have TELEAID. You would have to find a independent shop that has the ability to do this.
