Automobile Ignition Coil Injector Solenoid Valve Idle Stepper Motor Meter QDB-2A Motor Fault Detector Diagnostic Driver Disk Test Kit
220.00 AED
QDB-2A automotive actuator driver and signal-testing kit for supported coils, injectors, valves and motors. Confirm the exact component type, drive voltage, operating mode and supplied leads with JDTCL before selecting the tool.
The QDB-2A Automobile Actuator Fault Detector is a specialized diagnostic tool designed for automotive technicians and DIY enthusiasts to directly drive and test various engine components. It functions as a signal generator and driver, allowing you to verify the operation of actuators like ignition coils, fuel injectors, and stepper motors without needing the vehicle’s ECU.
Core Testing Capabilities
Ignition Coils: Supports 12V gasoline and 12V-24V natural gas coils, including independent, group, coil, and module types.
Fuel Injectors: Directly drives 12V gasoline and 12-24V diesel injectors (note: piezoelectric injectors are not supported).
Solenoid Valves: Tests duty cycle-controlled valves like fuel metering valves, EGR valves, and canister solenoids.
Motors: Drives electronic throttle motors, urea pump motors, and idle/instrument stepper motors.
Sensor Simulation: Can simulate Hall-type duty cycle sensors, such as air conditioning pressure sensors and air flow meters.
Key Technical Specifications
Power Supply: Operates on 12V-24V DC (recommended use of a car battery or a power supply capable of >5A for high-current pulse testing).
Adjustable Outputs:
Frequency Range: 1Hz to 100KHz.
Duty Cycle: 1% to 100%.
Hall Signal Amplitude: 1.25V to 11.5V.
Electromagnetic Coil Drive: Up to 3.5A.
Safety Features: Includes reverse connection protection and overcurrent protection that automatically cuts off power if current exceeds safety limits.
Common Testing Procedures
Component Frequency (Hz) Duty Cycle Connection Point
Modular Ignition Coil10–40 Hz 95–99% Hall signal output
Coil-Type Ignition Coil 10–40 Hz1–5%Electromagnetic coil drive
Fuel Injector10–40 Hz 1–5%Electromagnetic coil drive
Solenoid Valves/Motors 50–200 Hz 1–99% Solenoid coil drive
Crucial Warning: Always adjust the frequency and duty cycle before connecting the device under test to prevent accidental damage to sensitive components.
