The Electric Brake Force Meter with Dynamic Load Simulation and Circuit Testing tool, No. 9107A, from Innovative Products of America (IPA) utilizes patent-pending, dynamic load simulation technology to sync with a vehicle's trailer detection system, allowing the technician to quickly troubleshoot integrated and aftermarket brake controllers without needing a trailer. The tool displays real-time, brake-force output gain and timing, as well as truck-side tow circuit indication. Designed for 7-spade equipped vehicles, the tool automatically recognizes the electronic signature of both integrated (ITBC) and aftermarket trailer brake controllers. It simulates a trailer load and displays real-time, brake-controller output gain and application timing. In addition to the electric brake monitoring, the toolis ideal for troubleshooting all truck-side tow circuits, e.g., tail lights, turn signals, 12V+, reverse and ground condition, etc. The 25ft. cable allows for one-person, in-cab testing and is easily stowed inside the provided soft case.
