Strategic Tools & Equipment offers the CAN Bus Tester, a stand-alone device that conveniently connects to the vehicle with an OBD II connector. Once connected, LEDs light up instantly to show Data Link Connector pin activity and a quick indication of functionality. The tester instantly identifies DLC pins 1-16 and also identifies and monitors DLC pin signals. For more in-depth diagnostic work, the tech can connect the scan tool to the CAN bus tester, which is already connected to the OBD II port on the vehicle.
