Hi Everyone.

I have an issue with my car a Mercedes C280 2008 gasoline (the European version of c300), some days ago I received a message about (SRS malfunction visit workshop and the airbag light on), the car was not involved in any accident and the car started as usual.

Comment.
1-I checked all Fuses.
2-I interchanged the same type relays within the SAM
3-I checked Sam connection to de harness, all cables seems to be ok.
4-All systems seem to be working fine (expects SRS module N2/10).
5-I was not able to access the SRS module by using a X431 launch.
6-I have good current (12.7v) in all fuses within front and rear SAM’s.
7-I was not able to see, reach or scan the module with a Xentry/Das scanner and not able to access the module seems to be off or not installed, all other modules are working fine. 8-I checked the connections under the seats (everything seems to be ok). 9-The seatbelt light and warnings are not working.

Please let me know if any suggestion.

I see you checked the connections under the seats....
Perhaps you need to replace the passenger front seat sensor?

Well probably yes i need to replace the passenger front seat sensor, but so far i can't access the srs module so i can get the code errors that is part of the main issue.
I'm looking for the way to access the module to retrieve the error. code
Thanks!

This may be repeating what you've probably checked already.
