Delving into the realm of vehicle diagnostics can seem daunting, but with the right tools, understanding your car’s health becomes significantly more accessible. For those aiming to troubleshoot engine lights, monitor vehicle network communication, or even perform advanced diagnostics, the OBDPro scantool emerges as a powerful ally. Unlike basic OBD2 scanners that merely read error codes, OBDPro offers a deeper dive into your vehicle’s systems, granting you capabilities that extend far beyond simple code retrieval. While devices like Obd2 Foolers exist for manipulating sensor readings, our focus here is on genuine diagnostics and gaining insightful data from your vehicle using the OBDPro scantool.
To embark on this diagnostic journey and effectively use your OBDPro scantool, you’ll require three essential components:
- The OBDPro Scantool: This is your core hardware, acting as the interface between your vehicle’s OBD2 system and your computer.
- A Computer: Whether you prefer a PC, a Pocket PC PDA, or a PalmOS device, you’ll need a computer to process and display the OBD data captured by the scantool.
- Diagnostic Software: Software is crucial for interpreting the raw OBD data. This program, installed on your computer, translates the vehicle’s network messages into readable diagnostic information.
This setup provides you with extensive functionality, transforming your OBDPro into a versatile tool, akin to a Swiss Army knife for in-vehicle network analysis. While many handheld OBD II tools on the market are limited to reading and clearing error codes, they fall short when it comes to in-depth analysis. They often cannot decipher new, proprietary messages introduced in modern vehicles. The OBDPro overcomes these limitations, offering a future-proof solution for comprehensive vehicle diagnostics.
Consider the typical cost of a check engine light diagnosis at an automotive repair shop, often reaching upwards of $70 just to identify the error code. With the OBDPro, you not only bypass this expense but also gain access to advanced diagnostic features. You can monitor crucial parameters like fuel consumption based on your driving habits and even control certain vehicle accessories, depending on your car’s capabilities. For instance, refer to the datasheet for examples, such as controlling power windows on GM vehicles.
Setting Up Your OBDPro Scantools
Setting up your OBDPro scantool is a straightforward process. Follow these steps to establish a connection and begin diagnosing your vehicle:

- Locate the DLC Connector: The first step is to find your vehicle’s Diagnostic Link Connector (DLC). Typically, this connector is situated beneath the dashboard in the driver’s compartment, often near the steering column. It might be covered by a small protective flap, so look carefully. You’re searching for a connector that resembles the one pictured below.

Connect the OBD Cable: Take the black OBD cable included with your OBDPro scantool. Connect the D-shaped end of this cable to the DLC connector in your vehicle. Next, connect the smaller connector at the opposite end of the OBD II cable to the OBDPro scantool, inserting it into the port labeled “CAR.” Upon successful connection, the power LED on the OBDPro should illuminate and remain lit, indicating that the unit is receiving power from the vehicle’s DLC. Once the red PWR LED is lit, proceed to the next step, connecting the OBDPro to your computer.
-
Connect to Your PC and Install Software: Install diagnostic software on your computer. A variety of OBD II software options are available, catering to different operating systems, including Windows, PDA’s and more. You can find a list of popular software choices here or on other online resources dedicated to OBD2 software. For advanced users, the OBDPro scantool can also be used with hyperterminal or similar serial terminal programs. Consult the datasheet for detailed instructions on using a serial terminal.
Connect the RS232/USB cable between your computer and the OBDPro scantool. Launch your chosen OBD diagnostic software. Within the software settings, you’ll need to configure the communication port to match the serial port your OBDPro is connected to. Crucially, ensure your car’s ignition is turned to the “ON” position (engine not necessarily running) for OBD2 data to be accessible. The “Accessory” or “Off” positions will not provide the necessary data flow.
Should you encounter any difficulties during the scantool setup process, the FAQ section on the OBDPro website offers valuable troubleshooting tips and solutions to common issues.
Note: For computers lacking a serial port, a USB version of the OBDPro scantool is readily available, simplifying the connection process for modern laptops and desktops.
