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 4. If not, continue to step 2.)
2.
Turn the ignition on. DO NOT start the engine.
Press and release the POWER/LINK
button to establish communication with the
vehicle's computer.
3.
Press and release the ERASE
button. A confirmation message shows
on the display.
- If you are sure you want to proceed
press the ERASE button again to
erase DTCs from the vehicle’s computer.
- If you do not want to continue with
the erase process, press the
POWER/LINK
button to exit the
erase mode.
4.
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. Press the DTC SCROLL
button to return to 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.
