4. OVERVIEW
1 LCD DISPLAY Indicates test results. It is a
backlit 2-line display with 8
characters on each line.
2 ENTER BUTTON Conrms a selection (or
action) from a menu list, or
returns to the main menu.
3 SCROLL BUTTON Scrolls through menu items or
cancel an operation.
4 OBD II CONNECTOR Connects the Code Scanner
to the vehicle’s Data Link
Connector (DLC).
6. OPERATION
6.1. READ CODES
WARNING! DO NOT connect or disconnect any test equipment with the ignition on or engine running.
6.1.1. Turn the ignition o.
6.1.2. Locate the 16-pin Data Link Connector (DLC) and plug into the Scan Tool cable connector to the DLC.
6.1.3. Wait for the LCD display to read “C.A.N.OBD2”.
6.1.4. Turn the ignition on. But do not start the engine.
6.1.5. Press the ENTER button. A sequence of messages showing the OBD2 protocols will be observed on the display until the vehicle
protocol is detected - SCAN...VPW → SCAN...PWM → SCAN...CAN → SCAN...KPW2000 → ISO9141 PROTOCOL.
NOTE: If a “LINK ERROR!” message shows up, turn the ignition o for about 10 seconds, check if the Scan Tool’s OBDII connector is
securely connected to the vehicle’s DLC, and then turn the ignition back to on. Repeat the procedure from step 5. If the “LINK ERROR”
message does not go away, then there may be problems for the Scan Tool to communicate with the vehicle.
6.1.6. Wait for the main menu to come up after a brief overview displaying the scanning results with the total number of DTCs and the overall
I/M Monitor Status.
6.1.7. Select “DTC” from the main menu by pressing the ENTER button.
NOTE: If there are no Diagnostic Trouble Codes retrieved, the display will indicate “NO CODES”. If there are any Diagnostic Trouble
Codes, then the total number of the Fault Codes followed by that of the Pending Codes will be reported on the display.
6.1.8. Read the Diagnostic Trouble Codes by pressing the SCROLL button.
NOTE: The rst code number will appear on the rst line of the LCD display, the numerical sequence of the code and the total number
of the codes stored will appear on the second line. To view additional codes, press the SCROLL button to scroll, as necessary, until all
the codes have shown. If the code retrieved is a pending code, a “PD” will show on the LCD display in the end. To view previous codes,
press the SCROLL button to scroll through to the end, and then start from the rst of the list.
6.2. ERASE CODES
NOTE: Erasing the Diagnostic Trouble Codes allows the Scan Tool to delete not only the codes from the vehicle’s on-board computer, but
also “Freeze Frame” data and manufacturer-specic enhanced data. Further, the I/M Readiness Monitor Status for all vehicle Monitors is
reset to Not Ready or Not Complete status. Do not erase the codes before the system has been checked completely by a technician.
6.2.1. If you decide to erase the DTCs, Select “2. ERASE” from the main menu by pressing the ENTER button.
NOTE: If the Scan Tool is not connected or no communication is established with the vehicle yet, then refer to “Reading Codes” section.
6.2.2. A message of “ERASE? YES NO” comes up asking for your conrmation.
6.2.3. If you do not want to proceed with erasing the codes, press the SCROLL button to exit.
6.2.4. If you do wish to proceed to erase the codes, then press the ENTER button.
6.2.5. If the codes are cleared successfully, an “ERASE DONE!” message will show on the display. Press the ENTER button to Return to the
main menu list.
6.2.6. If the codes are not cleared, then an “ERASE FAIL!” message will appear. Press the ENTER button to Return to the main Menu list.
HOT KEY: Press and Hold the SCROLL button for about 3 seconds will allow you to erase the DTCs more quickly than through the
main menu.
6.3. RETRIEVE I/M READINESS STATUS
IMPORTANT: I/M Readiness function is used to check the operations of the Emission System on OBD2 compliant vehicles. It is an
excellent function to use prior to having a vehicle inspected for compliance to a state emissions program.
• YES - all monitors supported on the vehicle have completed their diagnostic testing and the MIL light is not on.
• NO - at least one monitor supported on the vehicle has not completed its diagnostic testing, and (or) the “Check Engine”(MIL) light is on.
• READY - indicates that a particular monitor being checked has completed its diagnostic testing.
• Not RDY (NOT READY) - indicates that a particular monitor being checked has not completed its diagnostic testing.
• N/A - the monitor is not supported on that vehicle.
• → - a ashing Right Arrow indicates additional information is available on the next screen.
• ← - a ashing Left Arrow indicates additional information is available on the previous screen.
