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.
Unlike other codes which can be removed from the vehicle's
control module, PERMANENT codes cannot. This holds true
regardless of the tool being used or color of the status LED
display. PERMANENT codes will automatically erase when the
control module no longer detects the fault that originally
caused the code.
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 the status of all Monitors to a not run condition. To
set all Monitors to a DONE status, an OBD2 Drive Cycle must be
performed.
1. If not connected already, connect the
Scan Tool to the vehicle's DLC, and turn
the ignition "On.” (If the Scan Tool is
already connected and linked to the
vehicle's computer, proceed directly to
step 3. If not, continue to step 2.)
2. Perform the Code Retrieval procedure
as described on page 6.
