you req a diagostic check to diagnose the fault don,t just ask someone to knock the light out cos it will just come back on,the most common fault is the seat belt drivers side as this get used most,the other is the clockspring as we call it,its a small coil of plastic covered wire under the steering wheel,removal of the steering wheel is the only option to get at it.first and fourmost is a diagnostic check??
