When DTCs are erased from the vehicle's computer memo-
ry, the I/M Readiness Monitor Status program resets the sta-
tus of all Monitors to a not run "flashing" condition. To set all
of the Monitors to a DONE status, an OBD 2 Drive Cycle
must be performed. Refer to your vehicle's service manual for
information on how to perform an OBD 2 Drive Cycle for the
vehicle under test.
The Scan Tool must be connected
to the vehicle’s DLC to erase the
codes from the computer’s memo-
ry. If you press the ERASE
button when the Scan Tool is not
connected to the vehicle’s DLC,
the erase instruction screen dis-
plays.
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 com-
puter.
3. Press and release the ERASE but-
ton. 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 com-
puter.
- 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 confir-
mation message shows on the dis-
play. Press the DTC SCROLL
button to return to the DTC screen.
