ERASING DTCs
When the Scan Tool's ERASE function is used to erase DTCs
from the vehicle's on-board computer, manufacturer specific
data (where applicable) is also erased.
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 DTC’s from the computer’s memory as follows:
1. Connect the Scan Tool to the vehicle’s DLC. Press ENTER to
continue.
2. Turn the ignition ON. DO NOT start the engine.
3. Press and release ERASE
. A
confirmation message shows.
If you are sure you want to proceed,
select Yes, then press ENTER
to continue.
- If you do not want to proceed,
select No, then press ENTER
to exit the erase function.
4. If you chose to erase DTCs, the “To erase
DTC’s consult the vehicle’s service repair
manual...” screen displays. You must
consult the vehicle’s service repair manual
for procedures to erase DTCs.
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 problem that cause the DTC to set manifests itself.
