Quick fix for faulty airbag light If an airbag light comes on, there might be a quick fix that avoids an unnecessary garage trip. The nearside airbag is linked to a sensor in the passenger seat, via a multi-pin electric plug and socket just below. The plug can apparently become dislodged when the seat moves backwards and forwards, so a little bit of fiddling with plug and socket can often clear the error message. A very useful tip, thank you. Before fiddling with the connector, you need to leave the car switched off for half an hour to discharge any residual current in the electrics. Otherwise, you might trigger the airbag.
