Description

Take diagnostics to the next level with this all-in-one ignition coil and injector tester, upgraded for 2025. The QDB-4A drive simulator is designed to quickly test ignition coils, injectors, solenoid valves, stepper motors, and more—helping mechanics and technicians identify faults faster, prevent guesswork, and save repair time.

Features & Benefits

• Multi-Function Tester: Tests ignition coils (independent & module type), 12V gasoline injectors, 12V/24V diesel injectors, solenoid valves, idle stepper motors, urea pumps, and more.

• Simulates Sensor Signals: Adjustable hall signal output with frequency, amplitude, and duty cycle control to replicate various automotive sensors (airflow, AC pressure, etc.).

• Wide Voltage & Current Range: Operates on 12V–24V input with protection features (reverse connection & overcurrent). Supports up to 3.5A driving current.

• Precision Control: Adjustable duty cycle (1%–100%) and output frequency (1Hz–100kHz) for accurate and customizable testing.

• Large Display & Easy Operation: Upgraded interface with a clear screen and simple controls—ideal for workshops and field repairs.

• Compact & Lightweight: Portable design (17 × 9.8 × 2.8 cm, only 175g) makes it convenient for mobile mechanics or bench use.

• Essential Workshop Tool: Speeds up diagnostics, reduces unnecessary part replacements, and ensures accurate fault detection.
