1. Safety Precautions and Warnings
To prevent personal injury or damage to vehicles and/or the scan tool, read this instruction manual first and observe the following safety precautions at a minimum whenever working on a vehicle:
- Always perform automotive testing in a safe environment.
- Wear safety eye protection that meets ANSI standards.
- Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts.
- Operate the vehicle in a well-ventilated work area: Exhaust gases are poisonous.
- Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
- Use extreme caution when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components create hazardous voltages when the engine is running.
- Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual transmission) and make sure the parking brake is engaged.
- Keep a fire extinguisher and any test equipment while the ignition is on or the engine is running.
- Keep the scan tool dry, clean, free from oil/water or grease. Use a mild detergent on a clean cloth to clean the outside of the scan tool when necessary.

3. Connection and Settings
Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-pin connector where diagnostic code readers interface with the vehicle's on-board computer. The DLC is usually located approximately 12 inches from the center of the instrument panel (dash), under or around the driver's side for most vehicles. If the Data Link Connector is not located under the dashboard, a label should be present to indicate its location. For some Asian and European vehicles, the DLC is located behind the ashtray, and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle's service manual for the location.
Diagram showing the typical location of a vehicle's Data Link Connector (DLC) as 'NEAR CENTER OF DASH'.
Connection
- Turn the ignition off.
- Locate the vehicle's DLC socket. Refer to the diagram for typical location. If no DLC is found, please refer to the Automobile Repair Manual.
- Plug one end of the diagnostic cable into the DB15 connector of the tool, and connect the other end of the diagnostic cable into the vehicle's DLC.
- Turn the ignition on. The engine can be off or running.
- The system starts initializing and then automatically enters the main menu interface.

Screenshot of the System Setup menu, displaying options: Language, Contrast, Unit Of Measure, Beep Set, Tool Self-test.
- Language: This option enables you to set the user interface language.
- Contrast: It is used to set LCD contrast.
- Unit of measure: This option allows you to set the measurement unit.
- Beep Set: It is used to set On/Off the buzzer.
- Tool Self-test: This option allows you to test tools.
4. Diagnose
Select [OBD Diagnostics] in the Main Menu and press [ENTER]; the system will display "loading program, please wait", then enter the following screen:
Screenshot of the OBD Diagnostics menu, displaying options: Diagnostics, DTC Lookup, Review Data, Print Data.
OBDII/EOBD Diagnostics
This option presents a quick way to check for DTCs, isolate the cause of the illuminated Malfunction Indicator Lamp (MIL), check monitor status prior to emissions certification testing, verify repairs, and perform a number of other services that are emission-related. In the OBD Diagnostics menu, select [Diagnostics] and then press [ENTER], the system will enter the following screen:
Screenshot showing 'Linking to Vehicle' with CAN11 500K, and 'Waiting for vehicle to respond'.
When connected to the car ECU communication, the system will enter the following screen:
Screenshot of a diagnostic prompt asking 'Erase Previously Stored data to save data from this test?' with YES/NO options.
In the prompt screen, select [YES] to erase previously stored data, or [NO] to not erase previously stored data. The system will then enter the following screen:
Screenshot of the System Status screen, showing MIL Status (OFF), Codes Found (0), Monitors N/A (5), Monitors OK (3), Monitors INC (3).
After a moment, a screen similar to the Diagnostic Menu will appear:
Screenshot of the Diagnostic Menu, displaying options: Read Codes, Erase Codes, Live Data, View Freeze Frame, I/M Readiness, O2 Monitor Test.
Diagnostic Menu Functions:
- 1) Read Codes: This option is used to identify which section of the emission control system has malfunctioned.
- 2) Erase Codes: After reading the retrieved codes from the vehicle and certain repairs have been carried out, you can use this function to erase the codes from the vehicle. Before performing this function, please be sure the vehicle's ignition key is in the ON position with the engine off. NOTES: A. Before performing this function, make sure to retrieve and record the trouble codes. B. After clearing, you should retrieve trouble codes once more or turn the ignition on and retrieve codes again. If there are still some trouble codes in the system, please troubleshoot the code using a factory diagnosis guide, then clear the code and recheck.
- 3) Live Data: This option retrieves and displays live data and parameters from the vehicle's ECU.
- 4) View Freeze Frame: When an emission-related fault occurs, certain vehicle conditions are recorded by the on-board computer. This information is referred to as freeze frame data. Freeze Data is a snapshot of the operating conditions at the time of an emission-related fault. Note: If DTCs were erased, Freeze Data may not be stored in vehicle memory depending on the vehicle.
- 5) I/M Readiness: I/M refers to Inspection and Maintenance, legislated by the Government to meet federal clean-air standards. I/M Readiness indicates whether or not the various emissions-related systems on the vehicle are operating properly and are ready for Inspection and Maintenance testing. The purpose of the I/M Readiness Monitor Status is to indicate which of the vehicle's Monitors have run and completed their diagnosis and testing, and which ones have not yet run and completed testing and diagnosis of their designated sections of the vehicle's emissions system. I/M Readiness Monitor Status function can also be used (after repair of a fault has been performed) to confirm that the repair has been performed correctly, and/or to check for Monitor Run Status.
- 6) O2 Monitor Test: The results of the O2 sensor test are not live values but instead the results of the ECU's last O2 sensor test. Not all test values are applicable to all vehicles; therefore, the list generated will vary depending on the vehicle. In addition, not all vehicles support the Oxygen Sensors screen.
- 7) On-Board Monitor Test: This function can be utilized to read the results of on-board diagnostic monitoring tests for specific components/systems.
- 8) Component Test: The Component Test function lets you initiate a leak test for the vehicle's Component system. The tool does not perform the leak test, but signals to the vehicle's on-board computer to initiate the test. Before using the system test function, refer to the vehicle's service repair manual to determine the procedures necessary to stop the test.
- 9) Vehicle Info: This option displays the vehicle information, such as VIN (Vehicle Identification Number), CID (Calibration ID), and CVN (Calibration Verification Number).
- 10) Modules Present: This option displays the vehicle communication protocol type.
DTC Lookup
This option allows you to enter the fault code and view its detailed description.
Review Data
