YIQIXIN QDB 3A Auto Ignition Coil Tester, Fault Detector For IAC Valves
The YIQIXIN QDB-3A Auto Ignition Coil Tester is a compact, high‑performance diagnostic tool designed to simulate and validate critical automotive systems. Built to handle 12V and 24V environments, it enables independent ignition tests, fuel injector drive, solenoid valves, metering units, and idle/stepper motors with precise PWM control. By generating realistic duty cycles, frequencies, and voltage levels, it helps technicians quickly identify faulty coils, injectors, actuators, or control circuitry, reducing diagnostic time and guesswork.
Main Description
Key capabilities include driving ignition coils with configurable coil type and module type settings, testing gasoline and diesel fuel injectors, and exercising various duty‑ratio controlled components such as solenoid valves and metering units. The device also powers and tests idle stepping motors, instrument stepping motors, and even headlight follow‑up steering motors, making it a versatile lab tool for modern engine management systems. A Hall sensor feature offers adjustable output frequency, amplitude, and duty cycle to simulate feedback from sensors like occupancy, air conditioning pressure, or air flow meters that rely on duty cycles. The unit supports a broad voltage range (12V–24V) and includes reverse connection protection and overcurrent protection for safer bench testing. With PWM drive up to 100 kHz and a configurable voltage range (1.25V–11.5V), it mirrors real‑world operating conditions to reveal intermittent or performance‑based faults that would be missed by static tests. This upgraded QDB‑3A model brings robust, multi‑purpose testing to workshops and training labs who need rapid, reliable diagnostics with real‑world signal fidelity.

Benefits & Tips
- Diagnose ignition, fuel, and actuator issues in a single bench instrument by replaying realistic engine signals and measuring responses.
- Use the Hall sensor mode to emulate sensor feedback and verify control logic without removing components from the vehicle.
- Calibrate PWM outputs (1Hz–100kHz, 1%–100% duty cycle, 1.25V–11.5V) to reproduce precise operating conditions and uncover intermittent faults.
