For Kawasaki Versys 650 owners looking to tap into their bike’s data, connecting a smartphone OBD2 reader is surprisingly straightforward. Despite some online discussions suggesting complexity, the process becomes clear when focusing on the essentials, particularly if your Bluetooth OBD2 adapter supports the KWP2000 (ISO9141) protocol. While pre-made cables might exist, their compatibility isn’t guaranteed. This guide, drawing upon expert insights and practical experience, will walk you through creating a reliable DIY connection and explore options for Bluetooth Obd2 Discount scanners to make motorcycle diagnostics accessible without breaking the bank.
Understanding the Versys 650 OBD2 Connector
The Versys 650 features a 4-pin connector located under the seat, providing access to essential diagnostic data. This connector carries 12V power, ground, and the crucial K-line for communication. Forget about the L-line for now; the K-line is your primary focus for basic OBD2 functionality.

To interface with standard OBD2 tools, you’ll need to create a patch cable adapting the motorcycle’s 4-pin connector to a standard 16-pin OBD2 socket. Here’s how the wiring maps out:
- OBD2 Connector Pins 4 & 5 (Ground): Connect to GND (Black/Yellow wire on the Versys 650).
- OBD2 Connector Pin 7 (K-Line): Connect to K-Line (Labeled Pink/Blue in schematics, often appears Purple/Violet on the bike).
- OBD2 Connector Pin 16 (12V Power): Connect to VBAT (Brown/White wire).
While OBD2 pin 15 is designated for the L-line, it’s generally not needed for basic diagnostics on the Versys 650. You can leave it unconnected, or optionally connect it to the Light Green/Black (LG/BK) wire on the motorcycle if your OBD2 adapter and software utilize it.
Crafting Your DIY OBD2 Patch Cable
Creating a patch cable is a cost-effective approach, especially when looking for a bluetooth OBD2 discount solution. You’ll need:
- An OBD2 socket (easily sourced from auto parts stores or online).
- A compatible 4-pin connector (a salvaged Honda plug from an old project works perfectly).
- Automotive wire and connectors.
Simply wire the connectors according to the pinout guide above. Soldering the connections provides the most robust and reliable link.

Selecting a Bluetooth OBD2 Scanner: Finding Affordable Options
With your DIY cable ready, the next step is choosing a Bluetooth OBD2 scanner. This is where you can find significant savings and potentially snag a bluetooth OBD2 discount. Numerous affordable Bluetooth OBD2 adapters are available online, often marketed for cars but perfectly compatible with motorcycles using the KWP2000 protocol.
When searching for a bluetooth OBD2 discount, consider these factors:
- Protocol Compatibility: Ensure the scanner explicitly supports KWP2000 (ISO9141). Most generic ELM327-based scanners do, but double-check specifications.
- App Compatibility: Popular OBD2 apps like Torque (Android) and OBD Fusion (iOS) are excellent choices. Verify scanner compatibility with your preferred app.
- Features: Basic scanners read engine codes and live data. More advanced (and potentially pricier) scanners might offer features like ABS diagnostics or advanced sensor readings, but for initial diagnostics and monitoring, a basic scanner is often sufficient and more budget-friendly.

Putting It All Together: Software and Real-Time Data
Once you’ve connected your DIY cable and Bluetooth OBD2 scanner to your Versys 650, pair the scanner with your smartphone via Bluetooth. Launch your chosen OBD2 app, configure the connection to your Bluetooth device, and you should be able to access real-time engine data.
Apps like Torque provide customizable dashboards to display parameters like coolant temperature, RPM, speed, and more. You can also read and clear diagnostic trouble codes (DTCs), empowering you to understand and address minor issues yourself.
