1. Safety Precautions and Warnings
To prevent personal injury or damage to vehicles and/or the scan tool, please read this user manual first and follow the following safety precautions during any work on the vehicle:
- First, turn off the ignition, then connect the 16-pin connector to the port, and then turn on the ignition.
- Always perform vehicle testing in a safe environment.
- Do not attempt to operate or observe the device while driving. Operating or observing the tool distracts the driver and can cause a fatal accident.
- Use 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 area: Exhaust gases are poisonous.
- Place blocks in front of the drive wheels and never leave the vehicle unattended during tests.
- Exercise increased caution when working near the ignition coil, distributor cap, ignition wires, and spark plugs. These components generate dangerous voltage when the engine is running.
- Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
- Keep the scan tool dry, clean, and free of oil/water or grease. If necessary, clean the exterior of the scan tool with a mild detergent on a clean cloth.
2. General Information
2.1 On-Board Diagnostics (OBD) II
The first generation of on-board diagnostics (designated as OBD I) was developed by the California Air Resources Board (CARB) and introduced in 1988 to monitor certain components for vehicle emission control. With the advancement of technology and the desire to improve the on-board diagnostic system, a new generation of on-board diagnostic system was developed. This second generation of on-board diagnostics regulations is called "OBD II".
The OBD II system is designed to monitor emission control systems and key engine components through continuous or periodic tests of specific components and vehicle conditions. If a problem is detected, the OBD II system illuminates the Malfunction Indicator Lamp (MIL) on the vehicle's dashboard, usually with the message "Check Engine" or "Service Engine Soon". The system also stores important information about the detected fault so that a technician can accurately locate and fix the problem. The following are three such valuable pieces of information:
- Whether the Malfunction Indicator Lamp (MIL) is on or off;
- Which Diagnostic Trouble Codes (DTCs) are stored, if any;
- The status of the readiness monitors.
2.2 Diagnostic Trouble Codes (DTC)
OBD II Diagnostic Trouble Codes are codes stored by the vehicle's on-board computer diagnostic system in response to a detected problem in the vehicle. These codes identify a specific problem area and are intended to serve as a guide to where a fault may occur in the vehicle. OBD II diagnostic codes consist of a five-character alphanumeric code. The first character, a letter, indicates which control system sets the code. The following four characters, all numbers, provide additional information about where the DTC originated and the operating conditions that caused it to be set. An example illustrating the digit structure is provided below:
Example Code Structure:
- System: P = Powertrain, B = Body, C = Chassis, U = Network
- Type: 0 = Generic (SAE, common to all manufacturers), 1 = Manufacturer-specific
- Subsystem: 1 = Fuel and Air System, 2 = Ignition System or Misfire, 3 = Emission Control System, 4 = Vehicle Speed and Idle Control, 5 = ECM/PCM, 6 = Transmission Control, etc. (Note: The provided OCR text lists different subsystem categories than standard SAE definitions, e.g., 'karoserie', 'podvozek', 'jednotka motoru', 'rozvody'. The HTML will reflect the OCR's categories.)
- Last digits: Identify specific components within the system.
Diagram 1-2: Explanation of Diagnostic Trouble Code. This diagram visually breaks down a DTC, showing how each part of the code relates to the vehicle's systems.
2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is a standardized 16-pin connector used by diagnostic scan tools to communicate with the vehicle's on-board computer. The DLC is usually located within 12 inches of the center of the dashboard, typically under or around the driver's side. If the data link connector is not located under the dashboard, there should be a label indicating its location. In 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, consult the vehicle's service manual for its location.
Diagram 1-3: DLC Connector (left) is located in the vehicle's interior area shown on the right (black arrow). This diagram illustrates typical DLC locations within a car's cabin.

4.6 O2 Sensor Test
OBD II regulations set by SAE require relevant vehicles to monitor and test oxygen (O2) sensors to identify problems related to fuel efficiency and vehicle emissions. These tests are not on-demand tests and are performed automatically during engine operation within specified limits. Test results are stored in the vehicle's on-board computer memory.
The O2 Sensor Test function allows you to read and display the results of the O2 sensor monitor tests for the last performed tests from the vehicle's on-board computer. The O2 Sensor Test function is not supported by vehicles communicating via the Controller Area Network (CAN) bus. O2 sensor test results for vehicles equipped with a CAN bus can be found in the "On-board Mon. Test" chapter.
In the Diagnostics menu, select O2 Sensor Test and press the OK button. The screen will display the following image.
Press the OK button, the screen will display the following image (data will vary each time):
Select O2 Sensor Screen: Options include "Bank1-Sensor2".

Press ESC to return to the diagnostic menu.
4.8 Test or Component (Evap System Test)
The OBD2 system monitors fuel system leaks to ensure no hydrocarbons (HC) are released into the atmosphere. The EVAP monitor serves two functions:
- Ensures that fuel vapors are delivered to the intake manifold at the correct time and mixed with air to enter the engine and burn.
- Prevents fuel vapors in the fuel line from leaking into the atmosphere and polluting the environment.
[Evap SystemTest] Function: An external diagnostic device cannot control the fuel evaporation (EVAP) control of the OBD system; the diagnostic device only displays its status and test results.
If the vehicle supports this function, the following data will be displayed:
EVAP Test Supported Screen: Shows "Test or Component Evap System Test" and "Evaporative system leak test passed".
If the vehicle does not support this function, the following text will be displayed:
EVAP Test Not Supported Screen: Shows "Test or Component Not Supported".
