Hi,have a problem with my airbag light on all the time on my 93 mondeo,it just has a air bag on the drivers side with no seat belt pre tensioners! Changed the air bag,clock spring,module but light still on!Checked the fuse (fuse36) thats fine with power,the thing i cant work out is there is permanent live at the fuse but at the pins going into the module it is powered by 3of the pins when you turn on the ignition,there is no permanent live,is this right? Does anyone know what pin does what,i cant find a wiring diagram which tells me,not sure what else it can be,the light is on all the time
