Hello
I have a S60 2002 and i installed an amp for the speakers, then i have a message "SRS-Airbag Service Urgent" and the the stoplight didnīt work. I read and some other people has the same problem, how can i fix it?

Thanks for your help

 

Unfortunately, that requires a trip to the dealer to have that message reset. Typically happens when part of the vehicle's computers are disconnected with the battery connected. I'm not sure about the stoplight failure. Maybe fuse or bulbs blown.
