    Default DTC's Not Clearing

    I have a 2008 Cummins HD 6.7l. ECM is a CM2150D and I have a V3 Tuner. I have two DTC's showing but when I push clear (ign on but not running) nothing happens. Please advise.

    Of course DTC's will only clear if the fault has been remedied, I assume whatever it is complaining about has been fixed?
    I no longer monitor the forum, please either post your question or create a support ticket.
