2. Safety Information
Before operating the V100 OBD2 Scanner, please read and understand all safety precautions. Failure to do so may result in injury or damage to the vehicle or scanner.
- 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.
- Be extremely cautious when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components create hazardous voltages when the engine is running.
- Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
- Do not connect or disconnect any test equipment while the ignition is on or the engine is running.

4. Setup
Setting up your V100 OBD2 Scanner is a straightforward process:
- Locate the vehicle's 16-pin Data Link Connector (DLC). This is typically found under the dashboard on the driver's side.
- Ensure the vehicle's ignition is in the OFF position.
- Firmly plug the scanner's OBD2 connector into the vehicle's DLC.
- Turn the vehicle's ignition to the ON position (engine off). The scanner will automatically power on and begin linking to the vehicle's system.
5. Operating Instructions
The V100 scanner offers several key functions accessible via its main menu:
5.1. Reading Diagnostic Trouble Codes (DTCs)
To read codes, navigate to the 'Read Codes' option on the main menu and press the 'OK' button. The scanner will display any stored, pending, or permanent DTCs, along with a brief description of each code.
5.2. Erasing Diagnostic Trouble Codes (DTCs)
After addressing a vehicle issue, you can clear the DTCs. Select 'Erase Codes' from the main menu and confirm your selection. This action will turn off the Check Engine Light (MIL) and clear all diagnostic data.

5.3. Viewing Live Data Stream
The 'Live Data' function allows you to view real-time operational parameters from the vehicle's sensors. This can be crucial for diagnosing intermittent problems or verifying repairs. Select 'Live Data' and scroll through the available parameters.
5.4. I/M Readiness Status
The I/M Readiness function checks the status of the emission-related monitoring systems. This is useful for determining if the vehicle is ready for an emissions test. A 'Ready' status indicates all monitors have completed their diagnostic cycles.
5.5. Vehicle Information
Access the 'Vehicle Info' option to retrieve important vehicle identification details, including the Vehicle Identification Number (VIN), Calibration ID, and Calibration Verification Number (CVN).

5.6. Battery & Alternator Check
The scanner can also provide basic battery and alternator voltage readings. This helps in assessing the health of your vehicle's electrical system and preventing unexpected power issues.

6. Maintenance
To ensure the longevity and optimal performance of your V100 OBD2 Scanner, follow these maintenance guidelines:
- Keep the scanner clean by wiping it with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Store the scanner in a dry, cool environment away from direct sunlight and extreme temperatures.
- Avoid dropping the device or subjecting it to strong impacts.
- Regularly check the OBD2 cable for any signs of damage (fraying, cuts, bent pins). Replace if necessary.
7. Troubleshooting
If you encounter issues while using your V100 OBD2 Scanner, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | Loose connection to DLC; Vehicle ignition not ON; Blown fuse in vehicle's OBD2 circuit. | Ensure secure connection; Turn ignition to ON; Check vehicle's fuse box for a blown fuse. |
| Linking error / Cannot connect to vehicle. | Incorrect protocol; Vehicle not OBD2 compliant; Faulty DLC connection. | Verify vehicle compatibility (post-1996); Check DLC for damage; Try on another compatible vehicle. |
| No codes found, but MIL is on. | Pending codes not yet stored; Intermittent issue. | Check 'Pending Codes' menu; Drive vehicle under various conditions to allow monitors to run. |
| Screen is blank or frozen. | Software glitch; Power interruption. | Disconnect and reconnect the scanner; If issue persists, contact support. |
