Features: 1.Function: Professional detection of various ignition coils, fuel injectors, solenoid valves, stepper motors and other faults. 2.Features: The detector can drive test a variety of actuators, also simulate duty cycle type sensors, used to detect whether the actuator failure or line or ECU computer failure. 3.Safe Protection: With reverse connection protection and over current protection, automatic cut off when the current is too large. 4.Performance: Support test idle stepper motor, instrument stepper motor, headlight range stepper motor, etc., convenient and practical. 5.Advantages: The detector is a high performance accessory that can help you upgrade your car better and improve the efficiency of diagnosing car troubles. Specification: Item Type: Automobile Actuator Fault Detector Material: ABS and metal Main Functions: 1. Test ignition coil, 12V gasoline car ignition coil, 12- 24V natural gas car ignition coil 2. Test injectors: 12V gasoline injectors, 12-24V diesel injectors 3. Test various solenoid valves for duty cycle control, such as fuel metering valves, EGR valves 4. Test various duty cycle controlled motors, such as, electronic throttle motor, urea pump motor 5. Test idling stepper motors, instrument stepper motors, headlight range stepper motors, etc. 6. Hall signal with adjustable output frequency, amplitude and duty cycle. Electronic module for driving duty cycle control, also simulate duty cycle type sensors. For example: air conditioner pressure sensor (duty cycle type), air flow sensor (duty cycle type) 7. The power supply voltage is 12-24V, with reverse connection protection and overcurrent protection (automatically cut off when the current is too large) 8. Electromagnetic Coil Drive Current Range: 0-3.5A 9. Output Frequency Range: 1- 100KHZ 10. Duty Cycle Adjustment: 1-100% 11. for Hall Signal Amplitude 1.3-11.5V 12. Adjustable Voltage Output 1.3-11.5V Note: 1. Ignition coil (with power drive module inside), radiator fan drive module, urea pump motor module. 2. The above coils and motors are equipped with power amplifier modules, so only need to input the Hall signal to drive the test 3. The drive module generally has three lines, namely: power +, GND, signal input
