Freelander 1 SRS light staying on

I had to remove my front seats because of rain soaking the carpet.
Obviously I had to unplug the seatbelt cables.

Now the seats are back and the cables re-connected but the SRS light is staying on.

Is there a way to reset it without an obd or whatever they are called?
Will disconnecting the battery for a while do it?

This has now sorted itself.
Took around 30 minutes before it vanished.
