Good advice but get the codes read with VIDA first just to be sure...

If the SRS and the ANTI-SKID warnings appears at the same time when the fault was intermittent then it's more likely... but best to check.

It's a DIY job and the airbag is not a worry, but disconnect the batter and when you re-connect the battery do so with the ignition in POS II (i.e. so the first time it is powered - you are not sat behind it...)

That's the recommended practice, but factually you never hear of airbags going off on their own and the connectors on them short out the firing mechanism when you remove the plug. However a bag going off at very close proximity in the wrong place can cause serious injury or worse - it's an small but unnecessary risk. The main issue is if the system is powered up with the airbag disconnected - it will cause a permanent error to be logged which you will need VIDA (or similar) to clear.
