Setup and Connection

To begin using your WXKJD V100 scanner, follow these steps to connect it to your vehicle's On-Board Diagnostics (OBD-II) port.

1. Locate the OBD-II Port: The OBD-II port is typically located under the dashboard on the driver's side of the vehicle. Refer to your vehicle's owner's manual if you have difficulty locating it.
2. Turn Off the Ignition: Ensure the vehicle's ignition is in the OFF position before connecting the scanner.
3. Connect the Scanner: Plug the 16-pin OBD-II connector of the WXKJD V100 scanner firmly into the vehicle's OBD-II port.
4. Turn On the Ignition: Turn the vehicle's ignition to the ON position (do not start the engine). The scanner will power on automatically.

Button Functions:

• UP/DOWN Arrows: Navigate through menu options and data lists.
• OK Button: Confirms a selection or enters a submenu.
• EXIT Button: Returns to the previous menu or exits a function.
• DTC Button: Directly accesses the Diagnostic Trouble Code (DTC) lookup function.

Key Functions:

1. Read Codes: Select this option to retrieve current, pending, and permanent Diagnostic Trouble Codes (DTCs) stored in the vehicle's computer. The scanner will display the code and a brief description.
2. Erase Codes: After addressing the underlying issue, select this option to clear all DTCs from the vehicle's computer and turn off the Malfunction Indicator Lamp (MIL). Note: Clearing codes without fixing the problem will result in the codes reappearing.
3. Live Data: View real-time sensor data from the vehicle's engine control unit (ECU). This includes parameters such as engine RPM, vehicle speed, oxygen sensor readings, and more. This data can help diagnose intermittent issues.
4. Vehicle Information: Access information such as the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN).
5. I/M Readiness: Check the status of the vehicle's emission-related monitoring systems to determine if they are ready for an emissions test.

Maintenance

Proper maintenance ensures the longevity and reliable operation of your WXKJD V100 scanner.

• Cleaning: Use a soft, dry cloth to clean the scanner's casing and screen. Avoid using abrasive cleaners or solvents, which can damage the device.
• Storage: Store the scanner in a dry, cool place, away from direct sunlight and extreme temperatures.
• Cable Care: Do not bend or crimp the OBD-II cable excessively. Always grasp the connector when plugging or unplugging, not the cable itself.

Troubleshooting

If you encounter issues while using your WXKJD V100 scanner, refer to the following common troubleshooting tips:

• No Power/No Display:
  • Ensure the OBD-II connector is securely plugged into the vehicle's port.
  • Verify the vehicle's ignition is in the ON position.
  • Check the vehicle's fuse for the OBD-II port (usually labeled "Cigar," "Accessory," or "OBD").
• Communication Error:
  • Confirm the vehicle supports the OBD-II protocol (most vehicles manufactured after 1996 in the US, 2001 in the EU for gasoline, 2004 for diesel).
  • Ensure the connection is secure.
  • Try the scanner on a different OBD-II compliant vehicle to rule out a scanner issue.
• Codes Not Clearing:
  • Ensure the underlying fault has been repaired. If the fault is still present, the codes will immediately reappear.
  • Follow the "Erase Codes" procedure carefully.
