How do I erase Diagnostic Trouble Codes (DTCs) from my vehicle's computer?

After completing the code retrieval procedure, press and release the ERASE button — the display will show 'SurE' to confirm. Press ERASE again to proceed, and the display will show 'donE' before automatically re-linking to confirm codes have been cleared. Note that erasing DTCs also clears Freeze Frame data and resets all Monitor statuses to 'not run,' requiring an OBD2 Drive Cycle to restore them. If you plan to take the vehicle to a service center, do not erase codes beforehand. (Page 20–21)
