ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When the Scan Tool’s ERASE function is used to erase
DTCs from the vehicle's on-board computer, "Freeze
Frame" data and manufacturer-specific enhanced data are
also erased. "Permanent" DTCs ARE NOT erased by the
ERASE function.
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, the I/M Readiness Monitor Status
program resets status of all Monitors to a not run condition. To
set all Monitors to a DONE status, an OBD2 Drive Cycle must
be performed.

If not connected already, connect the
Scan Tool to the vehicle's DLC, and
turn the ignition "On.” (If the Scan Tool

Perform the Code Retrieval procedure
as described on page 6.
