The HVIL testing tool is designed to verify the integrity of high-voltage interlock loop systems within electric or hybrid heavy-duty vehicles. It allows technicians to simulate and test the electrical safety interlocks that prevent accidental contact with high-voltage components during maintenance. By ensuring these safety circuits are functioning correctly, the tool helps prevent electrical accidents and ensures compliance with safety standards. Its user-friendly interface simplifies complex testing procedures, making it accessible even for less experienced technicians. Regular testing of HVIL systems is critical to maintain vehicle safety and operational reliability, especially as electric and hybrid trucks become more prevalent. Source One Parts Center offers this testing instrument as part of their safety equipment lineup for electric vehicle servicing.
