This is probably a seat sensor but it could be the pretensioners or the air bag. When the vehicle is started, there is a sensor test that is run on the SRS (air bag) and if it finds something wrong, the light comes on. Given that this is a life safety device and there are hazardous parts in it, you should take it to a dealer to have it worked on.

SOURCE: How do you access the spark plugs 2002 mercury mountaineer

IIRC these are a coil over design. meaning the coil is over the plug. the coil should have one 8mm bolt holding it on the lower intake manifold. remove the coild to get to the spark plugs. look by the fuel injectors, coil should be just next to it or very close. coil usually says motorcraft on it and circle in design.

good luck

SOURCE: airbag light on what does that mean

It means that your airbag system is not fully functioning and you need to have the dealer check it out. Whenever the airbag light stays illuminated after starting the vehicle, it means that there might be a problem with the air bag system and a check up is needed ASAP to make sure the system will operate properly in the event of an accident. It could be a faulty sensor, or it could be that a wire or connection is loose, etc., in any case, the dealer will need to check the airbag system to determine what the problem is.

I had a situation where an stereo installer had probed the wires in the airbag system and that caused the system to become non-functional, due to having voltage applied to the airbag wiring where it shouldn't have any voltage. It was an expensive fix, as he'd actually stripped the wires bare and he crossed several. Cost him a bunch to replace the wiring harness on my new vehicle.

SOURCE: brake lights stay on when vehicle shut off

The BRAKE LIGHT SWITCH needs to be Readjusted, Simply Move it Closer to Pedal Arm to Adjust. There is a NUT that you must Turn to do this. If you take a Good Look at it it is SELF EXPLANITORY.
I Hope this Helps , Well I Know it Will as it5 is OBVIOUS as to what the Problem is. Have a Good Day

Airbag light stays on


Hey,
take a look at www.airbagmodul.com

Airbag light on instrument panel flashes then stays illuminated


Some vehicles you can disconnect the battery for 10-20 mins and it usually resets a check engine light. But the airbag light is different. This means there is something wrong with the airbag system and it will not go out until maintenance.

Airbag light flashing 5times and 2times, does this 3 times then stays on


The code does have a definition, but you need a Ford NGS (new gen star) tester to read it, that is why the dealer is always the best place to get these kind of problems looked at.
