V320 OBD2 Diagnostic Scanner – Full System Code Reader

The V320 OBD2 Diagnostic Tool is a powerful, user-friendly scanner designed to help drivers quickly identify, analyze, and clear vehicle faults. It supports nine OBD II/EOBD protocols, works with all OBD II–compliant vehicles, and includes advanced diagnostic functions usually found in higher-end tools.

Key Diagnostic Features

OBD II/EOBD Protocol Support

The V320 supports nine standard automotive protocols, ensuring compatibility with most car models:

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

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

ISO 9141-2 – A protocol that uses a 5 baud rate for initialization, followed by communication at a rate of 10.4Kbaud.

ISO 14230-4 KWP – A protocol that uses a 5 baud rate for initialization, followed by communication at a rate of 10.4Kbaud.

ISO 14230-4 KWP –  Same as above, but with fast initialization.

ISO 15765-4 CAN (11bit ID, 500Kbaud) – A CAN bus communication protocol that uses an 11-bit identifier and a 500Kbaud rate.

ISO 15765-4 CAN (29bit ID, 500Kbaud) – Same as above, but with a 29-bit identifier.

ISO 15765-4 CAN (11bit ID, 250Kbaud) – A CAN bus communication protocol that uses an 11-bit identifier and a 250Kbaud rate.

ISO 15765-4 CAN (29bit ID, 250Kbaud) – Same as above, but with a 29-bit identifier.
