ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When the Scan Tool’s ERASE function is used to erase
the DTCs from the vehicle's on-board computer, "Freeze
Frame" data and manufacturer-specific enhanced data are
also erased.
If you plan to take the vehicle to a Service Center for repair, DO NOT
erase the codes from the vehicle's computer. If the codes are erased,
valuable information that might help the technician troubleshoot the
problem will also be erased.
Erase DTCs from the computer's memory as follows:
When DTCs are erased from the vehicle's computer memory,
the I/M Readiness Monitor Status program resets status of all
the Monitors to a not run "flashing" condition. To set all of the
Monitors to a DONE status, an OBD2 Drive Cycle must be
performed. Refer to your vehicle's service manual for
information on how to perform an OBD2 Drive Cycle for the
vehicle under test.
