If your airbag light on your 90-96 Q45 or similar year Infiniti vehicle is blinking, chances are it has been inadvertently been set into self diagnosis mode.It does not indicate a problem with the airbag system.Unplugging the battery will NOT clear the self diagnosis status.
To do this procedure, turn the vehicle on (engine not started) with the drivers side door open.Within 10 seconds of doing that, press the drivers side door switch more than 10 times within those 10 seconds.If you did the procedure correctly, the airbag light should go off.If it does not go off, it means there is a fault with the airbag system.
