Take a look at the DatacliQ for reading SAE J1708 and ISO 11992 bus signals.

It used to be difficult to read data safe and reliable from a vehicle data network. After finding the right CAN bus wires you had to find a good place to connect, strip the wires and solder or crimp to make a physical connection to the CAN bus.

In response to this, we introduced CANcliQ: the contactless CAN bus reader. The CANcliQ reads vehicle signals without making a wire to wire connection. This technology guarantees that no intrusive signals are sent to the vehicle CAN bus. This eliminates liability matters, warranty issues or possible wrong connections. Since its introduction in 2009 CANcliQ has proven itself as a reliable and safe solution.
