it would be handy if there could be an update for the code readers which would add support for diesel particulate filters. especially the following: 1. diesel particulate filter regeneration frequency reset/clear 2. diesel particulate filter differential pressure switch reset/clear 3. diesel particulate filter differential pressure switch reset/change/alter the stored pressure levels and the ability to carry out a forced regeneration would also be helpful for the 700 & 800 series readers.
