Automotive Circuit Diagnostics includes DM series products, OBD diagnostic boxes, and circuit test lead kits, which are essential tools for automotive circuit diagnostics. These tools ensure your work is safer and more efficient.

The AUTOOL DM series integrates embedded digital control technology, a digital oscilloscope, a digital multimeter, automotive circuit testing, and signal detection into one comprehensive Automotive Multimeter.

The Automotive OBD2 Protocol Box gives you easy access to the OBDII connector and displays real-time OBD2 interface voltages. With LEDs indicating power and ground conditions, it simplifies monitoring protocol, power, and ground signals securely.

Our various automotive circuit test lead kits allow direct connections to terminal backs without damaging the circuits. This reduces corrosion and prevents increased impedance while inspecting your car. When checking current, simply connect the circuit to the lead without cutting the wire.
