Professional VP37 RED4 Electronic Control Diesel Fuel Pump Tester and EDC Simulator

The VP37/RED4 Tester is a high-precision diagnostic instrument designed for the testing and maintenance of electronic control high-pressure diesel pumps. Its core driving module utilizes advanced ST (STMicroelectronics) current-mode analog control technology, perfectly replicating the ECU's control signals for high-pressure pumps. This device provides real-time digital displays of rail pressure and driving current, allowing technicians to observe parameter changes during calibration. Specifically optimized for VP37 and VE37 pump types, it features a built-in current protection system for safe operation. The tester also includes external wiring ports for convenient resistance checks, helping repair personnel quickly diagnose electrical faults in the diesel fuel injection system.
