Hi all

Got a question on behalf of my mum who has a DF LTD V8. She gave me a call telling me that her airbag light was on. She isn't very good with cars but I eventually got out of there that there is no error code, the light is on from when you turn the key and stays on. I found the table of errors on these forums and it says that a light fixed on with no flashing is a break down in communication with the diagnostic. I had a look at the only wiring diagram I have, from a Max Ellery service guide, and the only thing I can see talking to the diagnostic is the airbag module itself. Does this mean the module needs replacing?

Thanks in advance
