Bluetooth Dual-mode Automotive OBD Diagnostic Scan Tool

VC102 is a mini type auto scan tool for OBD-II diagnosis. It is with dual mode communication. Means the obd scan tool supports both Bluetooth 2.0 and Bluetooth 4.0. So that the compatibility of the auto scan tool is wider. Other type obd2 scan tool is with single Bluetooth 2.0 or Bluetooth 4.0. And the car scan tool supports more communication protocols than other obdii scan tool. So it is able to work with cars, SUVs, light trucks and heavy-duty trucks. When use the auto diagnostic scan tool with trucks, a conversion cable is required. It is compatible with Android, iOS and Windows devices.

Many others...

Note: The supported data of the obdii scan tool maybe updated when the App is upgrade.


Data Link Connector of Auto OBD Scan Tool

OBD-II requires that all automobile manufacturers to use a unified standard 16 pins Data Link Connector (DLC). The DLC is the right interface to connect with the OBD2 scan tool. That’s the basic requirement for OBD-II compliant vehicles. And it also ensure the compatibility of auto diagnostic scan tool and convenient for diagnosis.

But in practice, different automobile manufacturers use different OBD-II communication protocols and DLC pinholes. Generally speaking, European cars, Asian cars and Chrysler mostly use ISO9141-2 or ISO14230 (KWP2000) communication protocol. These two protocols use pinholes 4, 5, 7, 15 and 16. General Motors (Chevrolet, Buick, Cadillac, Hummer, Pontiac, Saturn, GM James) adopts the J1850 VPW protocol (pinholes 2, 4, 5 and 16). Ford Motor Company uses the J1850 PWM protocol (pinholes 2, 4, 5, 10 and 16). However, the ISO 15765 protocol (pinhole 4, 5, 6, 14 and 16) is widely used in the automobile production after 2008.

VC102 auto obd scan tool supports all these protocols, please feel free to order if your vehicle is equipped with the mentioned protocols.
