I have a couple codes that show up in my Nav screen under messages...an airbag warning from when my module was replaced (which the dealer failed to clear) and a P0174 emissions code which initially tripped the CEL, but later resolved itself. Can I clear these any way from home, or can only the dealer clear them?

 

if i am thinking of the same thing mine was showing, it showed on the acura messages on the navi and said contact dealer or something correct? if so, you can go into the service menu of the navi to delete it. I forgot how which tab is it on but it just resetting it. Acura said that it was nothing to worry about, and they just deleted for me right away. i'll try to figure out which tab it was on in the menu step by step. if you cannot find it.
