lots of airbag flash code questions are popping up of late so i have stuck this info in here so its easier to find as my old post with it all in is getting harder to find  :}

When an error occurs, your warning light may flash a code, made up of a flash sequence, a pause, then another sequence. Count the flashes in each sequence and use the flash code to find the associated cause below. For example, four flashes then nine gives a flash code of 49.
