I was hoping someone out there could assist me with deleting a P0420 DTC out of a calibration file for a 2003 Jeep Wrangler with a 4.0L engine. I read the file with my MPVI2 without any issue, opened the file, went to Engine Diag then DTC but no P0420 or P0430 in the DTC list. I have looked through every tab and cannot find anywhere to delete the P0420 dtc. I verified my view option with VCM editor was set to advance but still no P0420. I've done this on other vehicles with the older MPVI1 but it doesn't support this vehicle. Only the MPVI2. Any help would be greatly appreciated.
Thanks
