ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When the diagnostic 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 from the vehicle's computer memory, the
I/M Readiness Monitor Status program resets the status of all
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.
The diagnostic tool must be connected to the vehicle’s DLC to
erase the codes from the computer’s memory. If you press the
ERASE button when the diagnostic tool is not connected
to the vehicle’s DLC, the erase instruction screen displays.
1. If not connected already, connect the
diagnostic tool to the vehicle's DLC, and
turn the ignition "On.” (If the diagnostic
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 33.
„ To erase OBD2 DTCs: Wait until
the codes are displayed on the
diagnostic tool’s LCD and then
proceed to step 3.
„ To erase OEM enhanced, ABS or SRS DTCs: Perform the
Code Retrieval procedure for OEM enhanced DTCs as
described on page 39, for ABS DTCs as described on page 52,
or for SRS DTCs as described on page 54 Wait until the codes
are displayed on the diagnostic tool’s LCD and then proceed to
step 3.
