I have got recently my new Volvo S80, from day one the seatbelt warning tone is killing my nerves. I was asking my Volvo dealer if there is a way to disable the tone, but he explained to me that this isnt possible as the belt is an important safety feature. But latest today I cannot live with this safety feature anymore. I searched some Volvo forums, realized I was not the only one that wants to turn off the alarm, and found a forum member managed to disable it without any wiring but with the Vida Dice Volvo diagnostic tool. I have a Vida bought from eobd2.fr last year and rarely used it. This morning I took it out, hooked it up to my S80 and had no problem turn off the seat belt alarm. I write the steps out from memory, hoping it will help anyone.
Things you will need:
1.Volvo Vida Dice diagnostic device
The Vida I used is 2012A version. The latest version is 2014A according to eobd2.fr. The site has shared Vida Dice 2014A software, if interested: http://down.eobd2.fr/vida-2014a-torrent.zip
2.Windows 7 laptop
The software would run faster on Windows 7 operating system laptop.
Steps:
1) Install Volvo Vida Dice software. You can find its installation video online or follow the tips below:
1. Run the CD-ROM <\Install\DVD\Vida_dvdheader\Main\setup.exe>
