Erasing DTCs
ERASING DTCs (OBD I SYSTEMS)
When the CanOBD2&1 Scan Tool's ERASE function is
used to erase DTCs from the vehicle's on-board comput-
er, 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 CanOBD2&1 Scan Tool to the vehicle’s DLC. Press the
ENTER/LD button to continue.
2. Turn the ignition ON. DO NOT start the engine.
For FORD systems only, first perform step 3 below, then turn
ignition “ON” and press the ENTER/LD
button to continue.
3. Press and release the ERASE button. A confirmation message
shows on the CanOBD2&1 Scan Tool’s 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 ENTER/LD
button to exit the erase function.
4. If you chose to erase DTCs, a status
screen displays while the erase function
is in progress.
■ If the erase was successful, a confir-
mation message shows on the
CanOBD2&1 Scan Tool’s LCD dis-
play. press the ENTER/LD but-
ton to exit.
Due to the differences in computer systems, the
CanOBD2&1 Scan Tool can be used to erase codes for some
vehicles, while others require codes to be erased manually. If
the “To erase DTC’s consult the vehicle’s service repair man-
ual...” screen displays, you must consult the vehicle’s service
repair manual for procedures to erase DTCs.
