The airbag/seatbelt light in my 2003 Ford Focus Ink has started to flash. Sometimes it stays on, at others it goes off. I am wondering if there is a bad earth or connection? If so, where would I find it and how can I remedy it? Paul Wain When you turn on the ignition, the warning light should illuminate then go off, after which it will flash out a fault code in halfsecond flashes, followed by a pause. A code with one flash indicates a problem in the driver’s airbag area, while a code with two flashes indicates a passenger airbag. Three flashes alert you to problems common to both sides: four flashes indicate a pre-tensioner problem, five flashes an offside side airbag problem and six flashes a nearside side airbag problem. Using a scanner to retrieve a full fault code will give you a more precise cause, but the flash codes should point you in the right direction.
The airbag control module is located under the centre console, just behind the gear lever, and it may be worth checking the integrity of its connecting plug. One quite common area for problems is the front crash sensor, which is located on the bonnet slam panel – being right at the front of the vehicle, it is exposed to the elements.
