2. Safety & Warnings

Important Safety Information

• Read all instructions before use. Failure to follow these instructions may result in damage to the product or personal injury.
• Keep the device and its cord out of reach of children under 3 years old.
• Keep away from children unless supervised by an adult.
• Do not use this product for purposes other than its intended use.
• Inspect the product before each use; do not use if damaged.
• Follow installation and operation guidelines to avoid injury.

Diagnostic Best Practices

• Consultation First, Diagnosis Second: Carefully inquire about the vehicle owner's fault symptoms, occurrence conditions, and frequency. This forms the foundation for choosing the correct diagnostic path.
• Systematic Approach: Start from external checks to internal, and from simple to complex. First, check simple physical connections (plugs, fuses, grounding wires), then proceed to in-depth electronic diagnosis.
• Data Flow Superior to Fault Codes: Fault codes indicate a direction, while data flow provides concrete evidence. Always trust the data.
• Understand System Principles: Diagnostic tools are aids; the maintenance worker's understanding of the relevant system's working principles is key.
• Record and Archive: Store crucial fault codes, data flow screenshots, and maintenance procedures for easy reference and sharing of experiences.
• Continuous Learning and Updating: Automotive technology evolves rapidly. Regularly update the equipment software and your knowledge base.

5. Operating Instructions

5.1 Standard Connection Steps for Vehicle Diagnostics

1. Turn off the vehicle ignition switch.
2. Locate the vehicle's OBD diagnostic socket (usually found beneath the driver's side dashboard).
3. Insert the diagnostic connector firmly into the OBD port.
4. Connect the host (TK100) to the diagnostic connector.
5. Turn the vehicle ignition switch to the "ON" position (the instrument lights are on, but the engine does not start).
6. Turn on the power of the diagnostic equipment.

5.2 Vehicle Identification and System Selection

• Automatic Identification: Modern diagnostic devices usually support "automatic VIN scanning" or "automatic vehicle model recognition". This is the preferred method, as it minimizes the possibility of human error in selection.
• Manual Selection: If automatic identification fails, manual selection is required: Brand -> Model -> Year -> Engine model/Chassis number. Be precise in your selection; incorrect choices may result in communication failure or malfunction.
• Enter the Diagnostic Main Menu: After selection, the device will list all accessible electronic systems (e.g., Engine Control Unit (ECU), Transmission Control Unit (TCU), Anti-lock Braking System (ABS), Safety Airbag System (SRS), Body Control Module (BCM), Electronic Steering System (EPS)).

5.3 Reading Fault Information (DTC)

1. Read Fault Code (DTC): Enter the target system (e.g., engine system). Select "Read Fault Codes" or "Fault Code Scan". The equipment will display current and historical fault codes (e.g., P0300 - random/multi-cylinder misfire). Important: Record or take photos to save all fault codes.
2. View Details of the Fault Code: Click on the specific fault code to view its "definition", "setting conditions", and possible "fault point suggestions". This is key to understanding the problem.

5.4 In-depth Detection and Analysis

• Clear Fault Codes (Operate with Caution): Before repair, you can try to clear fault codes. If the fault is sporadic and does not recur, the problem may be resolved. Warning: Clearing fault codes will erase learning values and ready status, potentially causing temporary poor vehicle performance and affecting exhaust gas tests.
• Reading Data Stream: This is core to diagnosis. Choose "Read Data Stream" or "Dynamic Data". Select relevant parameter groups (fuel system, ignition system, intake system) or customize parameter selection.
  • Observation Points:
  • Outlier: Data significantly deviating from standard value range (e.g., long-term fuel correction of +25%).
  • Correlation: Whether related parameters show abnormal interconnections (e.g., throttle opening not matching intake volume).
  • Dynamic Changes: How data changes reasonably under different engine loads (idle, acceleration).
• Active Test / Movement Test (Actuation Test): The equipment can actively control actuator operation to determine performance. Common tests include controlling fuel pump, fuel injector spraying, relay activation, throttle motor movement, cylinder disconnection test, etc. Attention: Follow screen prompts strictly to ensure safety.
• Special Features:
  • Matching/Programming/Setting: Throttle matching, window anti-collision learning, steering angle sensor calibration, brake pad replacement reset, etc.
  • Control Unit Code: A code needs to be assigned after replacing the ECU.
  • Anti-theft Matching: Key programming (usually requires advanced permissions or dedicated software).
  • Reset Maintenance Light: Reset engine oil maintenance reminder.

6. Maintenance

6.1 Software Updates

The TK100 supports lifetime free upgrades. Keeping the software updated ensures compatibility with new vehicle models and improved functionality.

6.2 General Care

• Keep the device clean and free from dust and moisture.
• Store in a cool, dry place when not in use.
• Avoid dropping or subjecting the device to strong impacts.
• Charge the device using the provided Type-C cable and a 5V/2.0A charger. Do not use fast charge adapters.

7. Troubleshooting

7.1 Verification After Repair

1. Re-read the Fault Code: After repair, clear the fault code, run the vehicle for a period of time (or conduct a road test), then re-read the code to confirm that the fault has not reoccurred.
2. Recheck Data Flow: Verify whether abnormal data flow parameters have returned to normal.
3. Test Vehicle Functions: Conduct road tests to verify that the fault phenomena have completely disappeared.

7.2 Common Issues and Solutions

• Equipment cannot be turned on: Battery is dead (needs charging); power cord is faulty; equipment is damaged.
• No response after connecting the vehicle: The ignition switch is not turned on; the OBD interface power supply is faulty (check the fuse); the diagnostic connector is not properly connected; the vehicle model selection is incorrect.
• Unable to communicate with a specific system: The ECU of this system may have faults or there could be issues with the power supply or grounding; a dedicated adapter is required; the vehicle software does not support this system.
• Failed to read the fault code: Communication is unstable. Reconnect. Try to access other systems. If communication is possible, it indicates that there might be a problem with the vehicle network (such as a CAN bus failure).
• Function is grayed out and unavailable: The selected vehicle model/year model does not support this function; software upgrade is required; connection to the internet is necessary for online activation.
• Device freezing or lagging: Turn off the equipment, restart the vehicle and the diagnostic instrument; check if the software is the latest version.

8. User Tips

• Always ensure your TK100 device and the TPMS LINK app are updated to the latest version for optimal performance and compatibility.
• When performing relearn procedures, follow the on-screen instructions carefully, as different vehicles may have specific requirements.
• For complex diagnostic tasks, consider consulting the official user manual PDF for more in-depth guidance.
