96 Elantra airbag light

Unless your obd2 scanner also does air bag system's then no you can't reset it. Most of them do not do the air bag system if the light is on every key cycle then you will not be able to reset the light anyways. Every key cycle the computer does a check on the air bag system if there is no fault's found the light will go out. You need to have your car scanned for air bag code's that would be a starting point. Working on the air bag system can be dangerous if your not careful and know what your doing. They also require special tool's to diagnose.
