Need to log/stream OBD2 or CAN bus data from your car, truck or bus? This 1.5 meter OBD2-DB9 adapter cable fits the connector found near your car's steering wheel and lets you easi ly connect a CANedge CAN logger or CANsub CAN interface to start recording OBD2/CAN data. When buying a CAN logger/interface you can add this as an option for a 40% discount. OUTLINE TECH SPECS USE CASES FAQ CAR READY Fits your car's on board diagnostic connector (below steering wheel) TRUCK READY Type B - center pin hole enables use in 24V vehicles (e.g. trucks) SMALL Flat connector head for easy installation in tight areas SOLID CABLES Rugged quality 1.5m cable with overmolded DB9 connector ROHS Cables are RoHS compliant and tested in Denmark 1Y WARRANTY We offer a 1-year warranty on all our products About the DB9-OBD2 adapter The DB9-OBD2 adapter cable is used in passenger vehicles - incl. cars, taxis, light duty vehicles etc. It's also sometimes used heavy duty vehicles (trucks, buses, ...). The cable is compatible with our CANedge CAN loggers and CANsub CAN interfaces - letting you connect either directly to the CAN bus. To install, simply locate the OBD2 16-pin connector near your steering wheel - see also this location guide page. Need to use this with a CANsub.4/CANmod.router? See our DB25-4xDB9 adapter cable.

If you need to e.g. record data from a fleet of prototype cars for late stage field testing, the OBD2-DB9 adapter provides a simple way to connect your CAN logger. With direct access to the CAN bus, you can e.g. set up a CANedge3 to request OBD2 data along with the internally generated GPS/IMU data - and send it all via 3G/4G to your own server. Vehicle reverse engineering Need to reverse engineer the CAN bus of your car? If you want to truly understand your vehicle, you'll often need to reverse engineer the proprietary raw CAN bus data. Here, the OBD2-DB9 adapter offers an easy way to connect your CANsub CAN interface to your car. Once powered, you can stream the data in real-time via USB or Ethernet into webCAN in your browser. This way you're ready to hack your car in just a few minutes! For guidance, see our AI CAN sniffer article or our classic CAN sniffer article. Will the CANedge power off when my car is powered off? This differs from vehicle-to-vehicle: In some cars, the power supply will be turned off when you turn off the ignition (or a few seconds/minutes after), while in others the device will be powered also when the vehicle is off. The latter case is not an issue if you're only recording CAN bus data from the car. However, if you're requesting OBD2 data it may wake up the ECUs, causing faster battery drainage. In such cases, consider disconnecting the device - or use a control signal trigger to turn the OBD2 requests on/off (CANedge only). Show more
