OBD2 31
The ERASE button is active only when the Scan Tool is in
DTC display mode. The ERASE button is not active when
viewing Freeze Frame data, or when the Scan Tool is in “Live
Data” mode.
„ If you change your mind and do not
wish to erase the codes, press the
LD/ENTER

code retrieval function.
„ If you wish to continue, press the
ERASE
button again to erase
DTCs from the vehicle’s computer.

If you chose to erase DTCs, a progress
screen displays while the erase function
is in progress.
„ If the erase was successful, a
confirmation message shows on the
display. The Tool will relink to the
vehicle and display the DTC screen.
„ If the erase was not successful, an
advisory message shows on the
display. Verify that the Scan Tool is
properly connected to the vehicle’s
DLC and that the ignition is on, then
repeat steps 2 and 3, above.
Erasing DTCs does not fix the problem(s) that caused the
code(s) to be set. If proper repairs to correct the problem that
caused the code(s) to be set are not made, the code(s) will
appear again (and the check engine light will illuminate) as
soon as the vehicle is driven long enough for its Monitors to
complete their testing.
