Hey Ashraf , sorry it didn't sound right, but I 'm not up on all the vehicle acronyms for modules on here folk ,there are over 20 modules in these cars , please post what a front SAM abbreviation means. To me after watching the world news , it could just very well be a front mounted Surface to Air Missile instead of an achronym for something I would prefer not to be a SILLY AMERICAN MAN if people require me to google achronym on the internet for what a front SAM is (front signal acquisition module) not front mounted surface to air missile.
