The Innovative Products of America (IPA) Electric Brake Force Meter with Dynamic Load Simulation and Circuit Testing, No. 9107, was designed for use on seven-spade equipped vehicles. It automatically recognizes the electronic signature of both integrated trailer brake controllers (ITBC) and aftermarket trailer brake controllers, simulates trailer load and displays real-time, brake-controller output gain and application timing. In addition to the electric brake circuit, the tool is used for troubleshooting all truck-side tow circuits, such as tail lights, turn signals, 12V, reverse and ground condition. The 25' cable allows for one-person, in-cab testing and can be stowed inside the provided soft case.
