I know, the answer might be too late for You my friend, but airbag code 42 (4 flashes than 2 flashes) is the fault code of front crash sensor. Located at the bonnet lock behind the grill.
Check the connections, might be corroded if not, just replace the sensor (few quids)
Hope this helps for somebody else!!
To reset your airbag light, in a Nissan Altima, you should turn the car on. From there, as soon as the airbag light stops flashing, turn the car off instantly. Repeat this three times to reset the airbag light.
You have a air bag malfinction and should have a dealer chec the fault, your air bag system is non functional when the light is flashing
Your air bag light is flashing a code at you that means something is wrong with your air bag system
The flashing means that you have an airbag code. This means that there is a problem with your airbag, and your vehicles computer is trying to tell you to take it to the dealership to be fixed. Go see your nearest dealership soon. Do not worry, the airbag won't just go off randomly if their is a problem, the light is probably indicating that the airbag will not work if you get in an accident. A dealership will be able to interpret this code and tell you what is wrong.
It is flashing a code for you to use in determining the reason the flashing purpose. in other words it has determined that there is a problem with the air bag system. it will flash the code for 5 times and the the light will stay on. it will be a 2 digit code. count the flashes to determine the code. Your Ford dealer can tell you what the codes mean and where to look for the problem.

Some slightly better, more detailed instruction...Also works on the Armada Try This, I got this from ClubArmada.com It worked for me. Since some of you guys here are new owners I thought I'd save you a trip to the dealer once you start modifing your armada's. I'm not sure what set's it off (other than pulling things apart) but at some point you will likely end up with a flashing airbag sensor light. Here is how to reset it yourself. 1. Turn the key from off to on(not ACC). 2. Watch the airbag light closely. It will stay on for a few secs. and then as soon as it blinks off (the start of the flashing), turn the key off instantly. 3. Count to 5 secs(1 Mississippi, 2 Mississippi . . . .) 4. Repeat steps 1-3 two more times until you have done the cycle three times. 5. Now turn the key on and watch the light. It will start blinking in a different, slower manner. This is diagnostic mode. You can watch this for a little while, no hurry. 6. Now turn the key off again, Count to 5 like in step 3 again, and turn back on. If the procedure worked, the airbag light will not be flashing. Wola!!
Reset the light. Turn everything off. Turn the key on and off when the light just goes off. Keep doing this several times, the light will reset
Try disconnecting the battery cable, then reconnecting. If the airbag light still comes on, you need to take it to the dealer. Something in the airbag circuit isn't working correctly. To fix might involve removing the airbag. I've had the airbag light come on in my car two times & I've taken it to the dealer each time. I'm leery working around the airbag. You must disconnect the battery for a min of 5 mins
