I can’t clear the DTC’s with the MM3. I’ve been able to in the past if I remember correctly but for some reason I can’t this time around. The CEL was illuminated due to me unplugging various sensors for trouble shooting a separate issue. The CEL is no longer on ( I had to disconnect the batteries to get it to reset) but the codes still exist. Its almost as if they’re saved onto the tuner. Anyone else have any issues similar? Thanks ahead of time.

P.S. tunes are from DRD
