1. Binaural type, higher sensitivity, more prominent effect, better use, convenient detection, time-saving and labor-saving
2. Material: ABS
3. Application: automotive ECU detection coil
4. Application: suitable for cars with anti-theft chip sensor coils
5. Size: about 6.8 cm/piece
6. Weight: about 9g/piece

Principle of use:
1. Put the coil detector on the ignition switch
2. Turn on the key, the light on the coil is on, indicating that the vehicle is normal
3. If the light is off, it means that the anti-theft computer ECU is not working properly
4. Simple detection does not require special tools to detect, fast and convenient

Steps:
1. Place the inductor coil close to the ignition switch
2. Pass the key through the sensor coil, insert the ignition lock, and turn the key. At this time, the car anti-theft system works and starts to detect the chip key
3. By observing whether the anti-theft system is working properly

Analysis of test results:
1. The luminous tube flashes once and then goes out, indicating that the anti-theft system and chip key are working properly
2. The flashing time of the light-emitting tube is relatively long, indicating that the chip key does not match the vehicle's anti-theft system, and the chip key needs to be re-matched
3. The luminous tube does not flash, it means that the vehicle anti-theft system is faulty, please check the vehicle anti-theft system
