The DMTL or DHTML pumps are emissions parts related to the EVAP Sytem and the Secondary air pumps. So, it won't have an affect on the air bags.
You can go to any Auto Zone or Advance Auto and they will read the trouble codes for free with a good diagnostic reader. You can get a decent reader for a little over $100. You will have to translate the codes yourself, but we can do that for you if you can't find the code translation chart.
