Question about 2004 Mercury Mountaineer
Usually disconnecting the battery for anywhere from 10 - 30 mins resets any codes stored in memory.
Sometimes however it is a specific amount of "key cycling" that is required. eg: Turn key on, then off, then on for X seconds, then off for X seconds, then start engine etc. etc. etc.
If you have disconnected the battery, and there are no codes present but the light still comes on, there could be an issue with your airbag system. Wiring, or something was not done right.
WARNING : If you intend to work on the airbag yourself remember to disconnect battery for at least 45 mins. The air bag requires approx. 20-60 mins (depending on the vehicle, make and model and year) to discharge. If you do not do this you risk deploying the air bag, and that could ****!
