1. Introduction
The Jexiwe V320 OBD2 Scanner Code Reader is a powerful and user-friendly diagnostic tool designed to help you quickly identify and resolve issues with your vehicle's engine. It supports all OBDII/EOBD protocols and is compatible with most vehicles manufactured after 1996. This device requires no batteries as it is powered directly by your vehicle's OBD-II port.
Key features include reading and erasing Diagnostic Trouble Codes (DTCs), viewing live data streams, accessing freeze frame data, and performing I/M readiness tests for emission inspections.

2. Setup
The V320 OBD2 Scanner features a simple plug-and-play design for quick and easy setup.
- 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.
- Connect the Scanner: With the vehicle's ignition off, firmly plug the scanner's OBD-II connector into the vehicle's OBD-II port.
- Turn on Ignition: Turn the vehicle's ignition to the 'ON' position (do not start the engine unless instructed by a specific test). The scanner will power on automatically.

3. Operating Instructions
Navigate the scanner using the 'DTC', 'I/M', 'EXIT', 'OK' buttons and the directional arrows (Up, Down, Left, Right).
3.1. Diagnostic Menu Overview
The main diagnostic menu provides access to the primary functions:
- Read Codes: Retrieves Diagnostic Trouble Codes (DTCs) from the vehicle's computer.
- Erase Codes: Clears DTCs from the vehicle's computer and turns off the Malfunction Indicator Light (MIL).
- View Freeze Frame: Displays a snapshot of sensor data recorded when a fault code was set.
- I/M Readiness: Checks the status of emission-related monitoring systems.

3.2. Reading and Erasing Codes
- From the main menu, select 'Read Codes' and press 'OK' to view current, pending, or historic DTCs.
- To clear codes, select 'Erase Codes' from the main menu and press 'OK'. Confirm your selection when prompted. This will turn off the Check Engine Light.
3.3. Live Data Stream
The Live Data Stream function allows you to monitor various vehicle sensors and parameters in real-time. This can be crucial for diagnosing intermittent problems or verifying repairs.
- Select 'Live Data Stream' from the diagnostic menu.
- Use the Up/Down arrows to scroll through available parameters such as engine RPM, coolant temperature, fuel system status, and load percentage.

3.4. Built-in DTC Definitions
The V320 scanner includes a built-in database of Diagnostic Trouble Code definitions, eliminating the need for external searches.
- When a code is displayed, the scanner can provide a brief description of the fault.
- For detailed information, use the 'DTC Lookup' function if available in the menu.

3.5. I/M Readiness Test
This function checks the operational status of the vehicle's emission monitoring systems, which is essential for preparing for annual smog tests.
- Select 'I/M Readiness' from the main menu and press 'OK'.
- The scanner will display the status of various monitors (e.g., Misfire Monitor, Fuel System Monitor, Component Monitor) as 'OK' or 'INC' (Incomplete).

4. Maintenance
To ensure the longevity and optimal performance of your Jexiwe V320 OBD2 Scanner, follow these simple maintenance guidelines:
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending or twisting the OBD-II cable excessively. Always grasp the connector when plugging or unplugging to prevent damage to the pins.
- No Battery Maintenance: The V320 is powered by the vehicle's OBD-II port and does not require internal batteries, eliminating the need for battery replacement or charging.
5. Troubleshooting
If you encounter issues with your V320 scanner, consider the following common troubleshooting steps:
- No Power/Display: Ensure the OBD-II connector is firmly seated in the vehicle's port. Verify the vehicle's ignition is in the 'ON' position. Check the vehicle's fuse for the OBD-II port (consult your vehicle's manual).
- Communication Error: Ensure the vehicle is OBDII/EOBD compliant (most vehicles after 1996). Check for a stable connection. Try the scanner on a different compatible vehicle to rule out a vehicle-specific issue.
- Incorrect Readings: Ensure the vehicle's engine is running (if required for specific tests like live data) and at operating temperature.
- Engine Light Remains On After Erasing Codes: This indicates that the underlying fault has not been resolved, and the vehicle's computer has detected the issue again. Address the root cause of the DTCs before attempting to clear them permanently.
