I recently changed the alternator. The radio and the moon-roof are not working and SRS warning light is on the dashboard . Anyone knows how to reset the computer? thanks

 

Hi,
oh this case after replacing alternator... u need a diagnostic computer to clear off the trouble codes.. and it cant be done without the computer.. go to the garage that has the module for your merc or the dealer service center.

Good luck...

 

thanks. the radio is also dead. do you know how to reset the security code?
