Just though I would post this incase it helps somebody.....moving the passenger seat would clear the dashboard airbag light fault initially but then that stopped working.....I disconnected the car battery and played around with the junction box connections underneath the passenger side seat....re-connected the battery and light has not come back on since Black FL2
L200 Warrior

Indeed, that's the standard fix. And be warned - it doesn't show up as a fault code, so the dealer may well try to sell you a new airbag (they tried to do that to me)! Ex AA Series III LWB Safari - Gone
