The is an automotive actuator fault detector used to test components like ignition coils, fuel injectors, solenoid valves, and stepper motors. It simulates sensor signals by outputting adjustable frequency, amplitude, and duty cycles. 📄 Manual & Documentation
Before testing, it is critical to identify the type of ignition coil you have: (no internal driver) or "module type" (has an internal power driver). A 3-wire coil with a primary resistance of ~1Ω is a coil type; if the resistance is different, it is likely module type. qdb-2a manual pdf
Identify the pins on your ignition coil (Power, Ground, and Trigger). Connect the QDB-2A ground wire to the coil ground pin. The is an automotive actuator fault detector used
