Data Stream Reading: Real-time reading and display of car engine operating parameters such as engine speed, temperature, fuel consumption, etc.

Freeze Frame Information: When a fault is detected, it can record the vehicle status information at the time of the fault for later analysis.

Checking the Malfunction Indicator Lamp (MIL) Status: Check the status of the Malfunction Indicator Lamp (MIL) to understand if there is a fault with the vehicle.

Performance Test: Test the car's acceleration and braking performance, etc., to evaluate the vehicle's performance.

Reading Vehicle Information: Read basic vehicle information, such as VIN number, engine model, etc.

Oxygen Sensor Test: Test the operating condition of the oxygen sensor to evaluate the performance of the emission control system.

Fuel Evaporation System Test (Mode 8): Check if the fuel evaporation control system is working properly.

Error Code Information Request: Provides detailed error code information request to help users understand the meaning of faults.

Data Stream Playback Function: Allows users to view and clear fault codes, data streams and freeze frame information.

Multilingual Support: Supports eight languages, including English, German, Italian, Dutch, French, Spanish, Chinese and Russian, to meet the needs of different users.


Supported protocols
The V320 diagnostic device supports the following nine automotive communication protocols to ensure compatibility with OBD systems of different car models:

SAE J1850 PWM: A communications protocol that uses pulse width modulation signals with a transmission rate of 41.6 Kbaud.

SAE J1850 VPW: A communications protocol that uses voltage pulse width modulation signals with a transmission rate of 10.4 Kbaud.

ISO9141-2: A protocol that uses a 5 baud rate for initialization, followed by communication at a rate of 10.4 Kbaud.

ISO14230-4 KWP: A protocol that uses a 5 baud rate for initialization, followed by communication at a rate of 10.4 Kbaud.

ISO14230-4 KWP (Fast Initialization): Same as above, but with fast initialization.

ISO15765-4 CAN (11-bit ID, 500 Kbaud): A CAN bus communication protocol that uses an 11-bit ID and a data rate of 500 Kbaud.

ISO15765-4 CAN (29-bit ID, 500 Kbaud): Same as above, but with a 29-bit identifier.

ISO15765-4 CAN (11-bit ID, 250 Kbaud): A CAN bus communication protocol that uses an 11-bit ID and a data rate of 250 Kbaud.

ISO15765-4 CAN (29-bit ID, 250 Kbaud): Same as above, but with a 29-bit identifier.



Car Diagnostic Steps
Locate the OBD port: First, locate the vehicle's OBD port. The location of the OBD port varies by model, but is typically located on the lower left side of the dashboard, above the accelerator pedal. If unsure, refer to your vehicle's manual or search for the specific location using the vehicle model.

Connect the diagnostic device: Connect the V320 diagnostic device to the vehicle's OBD port using the provided connection cable.

Vehicle Start: After connecting the device, start the vehicle to allow the system to communicate.

Access Diagnostic Menu: After connecting to the vehicle, enter the main page of the V320 diagnostic tool and select the “OBD/EOBD” menu, then press the OK button to enter the test function page.

Select Test Functions: Use the arrow keys to navigate and select the desired test function. Test functions include performance testing, data stream, trouble code lookup, I/M readiness, voltage detection, and more.

Run the test: After selecting the appropriate test function, press the OK button to run the test. The diagnostic device reads the relevant vehicle information and displays the results.


Parameter Setting Steps
: Accessing Product Settings: In the main menu of the V320 diagnostic device, locate and select the “Product Settings” option.

Language Settings: In the settings menu, select the desired language, then use the directional keys to choose it and confirm with the OK button.
