- LED Light: Provides illumination for working in dark environments.
- Status Indicator LED1 (Yellow): Indicates strong magnetic field detection.
- Status Indicator LED2 (Red): Indicates normal test signal detection.
- Switch Light & LED Lighting Switch (Blue Button): Activates the LED light and initiates testing.
- Switches (I/II):
- 0: Power Off.
- I: High sensitivity test mode for strong magnetic fields.
- II: Normal test mode.
- Built-in AAA Battery Lock: Secures the batteries.
3. Setup: Battery Installation
The OBDEMOTO 101 requires two 1.5V AAA batteries for operation.
- Locate the battery compartment at the top of the device.
- Press the button to slide out the battery tray.
- Insert two AAA batteries, ensuring correct polarity (+ and - terminals).
- Slide the battery tray back into the device until it clicks securely into place.
- Push the button up to open the device for use.

4. Operating Instructions
Follow these steps to use your OBDEMOTO 101 detector:
- Power On: After battery installation, ensure the switch is in position 'I' (strong magnetic test) or 'II' (normal test).
- Select Test Mode: Use the slide switch to select between 'I' for high sensitivity testing (e.g., power lines) or 'II' for normal component testing.
- Initiate Test: Press the blue button to activate the device and begin scanning for faults.
- Position the Detector: Place the tip of the detector near the automotive electrical component you wish to test.
- Observe Indicators: The LED indicators and beeper will provide feedback on the component's status.
- LED Flashlight: Press the blue button briefly to turn on the LED flashlight for improved visibility in dark areas.

5. Test Range
The OBDEMOTO 101 is capable of testing a variety of automotive electronic components, including:
- Ignition Coils (traditional coil, double spark coil, single spark coil)
- Generators
- Cooling Fans
- Electric-magnetic Valves
- Emission Gas Controlling Valves
- Fuel Injectors
- Relays
- Other automotive electrical parts

6. Interpreting Results
The detector provides feedback through LED indicators and an audible beeper:
- Normal Operation: If the component is functioning correctly, both LED1 (yellow) and LED2 (red) will flash, and the device will emit a continuous beeping sound.
- Fault Indication: If the component is damaged, shorted, or disconnected, there will be no beeping sound, and the LED indicators may not flash or behave erratically.
Example: Ignition Coil and Generator Test

- Ignition Coil - Not Working: Status indicator LED1 and LED2 are off, no beeper sound.
- Ignition Coil - Working: Status indicator LED1 and LED2 are flashing, beeper makes sound continually.
- Generator - Not Working: Status indicator LED1 and LED2 are off, no beeper sound.
- Generator - Working: Status indicator LED1 and LED2 are flashing, beeper makes sound continually.
7. Safety Precautions
Adhere to the following safety guidelines when using the OBDEMOTO 101 detector:
- Perform tests in a well-ventilated area to avoid inhaling exhaust fumes.
- Keep the detector away from sources of fire and ensure the work area is free of flammable materials. Gasoline and charged batteries can pose explosion risks.
- During testing, avoid moving parts and heat sources to protect both the user and the equipment.
- Stay clear of the engine's cooling fan.
- Do not place other equipment on the battery, as this may cause a short circuit and damage the tester or other equipment.
- Turn off the ignition switch before connecting or removing electrical parts.
- Do not leave the car unattended during testing.
- For automatic transmission vehicles, confirm the gear position is in 'P' (Park). For manual transmission vehicles, apply the parking brake before driving the tires.
- Always refer to your car manufacturer's warnings and important information.

8. Maintenance
To ensure the longevity and proper functioning of your OBDEMOTO 101 detector:
- Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Store the detector in a cool, dry place when not in use.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
- Avoid dropping the device or subjecting it to strong impacts.
9. Troubleshooting
If you encounter issues with your OBDEMOTO 101 detector, consider the following:
- Device does not power on:
- Check if batteries are installed correctly with the right polarity.
- Replace batteries with new ones.
- Ensure the power switch is in position 'I' or 'II'.
- No beeping or LED indication during test:
- Verify the component being tested is powered and operational.
- Ensure the detector tip is in close proximity to the component.
- Switch between 'I' (strong magnetic test) and 'II' (normal test) modes to see if sensitivity is an issue.
- The component may be faulty.
- Inconsistent readings:
- Ensure a stable connection and proper positioning of the detector.
- Test in an environment free from strong electromagnetic interference.
