- Establish Bluetooth Connection: Ensure Bluetooth is enabled on your smartphone. The Ediag App will automatically search for and connect to the Ediag Elite device. Do not attempt to pair the device directly through your phone's Bluetooth settings.
- Download Diagnostic Software: Within the app, download the specific diagnostic software for your vehicle's make and model. This may require an internet connection.
ECT200 Automotive Electrical Circuit Tester Setup:
- Connect to Power: Connect the red clamp of the ECT200 to the vehicle's positive battery terminal and the black clamp to the negative battery terminal. The device will power on automatically.
- Familiarize with Indicators: Observe the digital display and LED indicators. A red LED indicates a positive pole, while a green LED indicates a negative pole.
Operating Instructions
Operating the Ediag Elite OBD2 Scanner:
- Initiate Diagnosis: From the Ediag App's main interface, select "All Systems Diagnostics" to perform a comprehensive scan of your vehicle's systems.
- Read and Clear Codes: View diagnostic trouble codes (DTCs) and their descriptions. The app allows you to clear these codes after repairs are made.
- Live Data Stream: Access real-time data from various vehicle sensors and modules. This includes parameters like oxygen sensor voltage, fuel trim, engine RPM, vehicle speed, and temperatures. This data is crucial for advanced diagnostics.
- Bi-Directional Control (Active Test): Navigate to the "Maintenance Functions" or "OBD Functions" section and select the active test feature. This allows you to command specific components to turn on or off, verifying their functionality. Examples include activating wipers, controlling headlights, or opening/closing doors.
- Maintenance Functions: Utilize the 15+ special functions for routine maintenance, such as resetting oil life, performing brake resets, or calibrating steering angle sensors.
- VIN Scan: Use the VIN scan feature to automatically decode vehicle information based on the NHTSA database.
- Generate Reports: The app can generate diagnostic reports, which can be saved or shared for record-keeping or professional consultation.
Operating the ECT200 Automotive Electrical Circuit Tester:
- Voltage Testing: Touch the probe tip to the circuit or component you wish to test. The digital display will show the voltage reading. The red/green LEDs indicate polarity.
- Component Activation: To activate a component, connect the probe tip to its power input. Use the switch on the tester to apply positive or negative voltage. This is useful for testing motors, lights, and relays directly.
- Continuity Testing: Connect the probe tip to one end of the circuit and the ground clip to the other. The device will indicate continuity with an audible tone and/or visual indicator.
- Short Circuit Finding: Use the probe to trace circuits. The device will indicate a short circuit by changing its display or tone.
- Diode Test: Test diodes by applying voltage with the probe and observing the current flow.
- Tracking and Ground Detection: The ECT200 can assist in tracking wires and identifying proper ground connections within the vehicle's electrical system.
