· Instantly check power and ground circuits

· Identify communication link protocols

· Constantly monitor Battery Voltage with display

This device is ideal for use when fitting an OBD Blocker – it allows you to check the OBD Port connections, before and after the fitment of the OBD Blocker.

Customers will ask, how do I know it is working? Now you can show them - the TDB014 has LED's for power and ground connections, along with LED's for the communication lines. You can quickly see the CAN BUS lines flashing when the OBD Blocker is not fitted, and once fitted there is no connection. Allowing you to test the OBD Blocker is working.
