On some models, DTCs may set as a result of reprogramming. If DTCs are present, clear codes and run the Health Check again. Troubleshoot
any remaining Current, Pending, or History codes. Permanent codes will not be cleared using Techstream. Permanent codes do not illuminate
the MIL and do not require troubleshooting. They will clear during normal driving once the Universal Trip Drive Pattern is performed.
