ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When the Code Reader’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.
