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 lets you connect your CAN logger directly to the CAN bus.

To install, simply locate the OBD2 16-pin connector near your steering wheel - see also this location guide page.

Below are two use cases examples where the OBD2-DB9 adapter is useful:

Prototype Vehicle Fleet Field Logging OBD2

Vehicle fleet telematics

Need to log OBD2 data from a car fleet?

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 CAN logger to your car. Once powered, you can connect the CLX000 to your PC via a standard mini USB to start streaming data in SavvyCAN. This way you're ready to hack your car in just a few minutes!

Reverse Engineer Vehicle CAN Bus OBD2



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).
