Erasing DTCs
ERASING DTCs (OBD I SYSTEMS)
When the Tool's ERASE function is used to erase DTCs
from the vehicle's on-board computer, manufacturer spe-
cific 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 Tool to the vehicle’s DLC. Press the ENTER/FF
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/FF
button to continue.
3. Press and release the ERASE button. A confirmation message
shows on the LCD 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/FF
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 Tool’s
LCD display. press the ENTER/FF
button to exit.
Due to the differences in computer systems, the 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 manual...” screen displays, you
must consult the vehicle’s service repair manual for proce-
dures to erase DTCs.
