That doesnt mean too much, read the code with a dedicated scanner which gives you a clear description of the fault and reveal that

I'll try again... I cleared the codes to see if it was fine, before realising it self-tests and will stay off if AOK.

Ok - my son says the faults are on the left and right pre-tensioners, failure at ignition and failure to ground. Sounds like the module under the cubby box?

Clear the codes, unplug both pretensioners and read again... if the codes dont change in open circuits then the DCU becomes suspect

So read while unplugged?

Yes, to check if the DCU reacts well or not

Update. He cleaned the ground on one pretensioner and it has come right so he is trying the one with ignition fault code clearing, unplugging and reading.

Update, the unplugged ignition fault pretensioner returns open circuit fault... so if reading open circuit DCU is AOK and replace the pretensioner?
