Why should you choose Echo Wireless Scanner ?
- This ECHO Bluetooth wireless scanner is designed for users looking for excellent value and practical diagnostic performance.
- Conventional handheld diagnostic scanners have several limitations: they rely on wired connections for vehicle diagnostics, while their functions are largely restricted by built-in hardware and software. In addition, the cost of integrated hardware can significantly increase the overall price of the device.
- In comparison, the ECHO wireless scanner connects directly to your smartphone via Bluetooth, offering greater portability, easier operation and more flexible diagnostic capabilities than traditional wired handheld models. You can perform vehicle diagnostics conveniently wherever you need them.
- It is also a practical tool for used car dealers. ECHO can help identify hidden vehicle issues and abnormal diagnostic data, including signs of previous repairs, VIN-related abnormalities, mileage-related inconsistencies and other potential problems that may not be visible during a standard inspection.
- While some Bluetooth diagnostic products require paid subscriptions or renewals after a limited period of free use, ECHO provides lifetime free use with no subscription fees, allowing you to continue using supported diagnostic functions without recurring software costs.

Bi-Directional Control & Active Test:
- Echo can communicate with the vehicle ECU and activate individual components for targeted testing, including sunroofs, fuel injectors, seats, wipers, lights, air conditioning, and more. By checking the actual response of each actuator, users can determine whether a fault is related to the circuit, control module, or actuator.

• Send commands directly to the ECU to trigger specific actions, such as opening or closing the sunroof, switching lights or A/C on and off, and more. This allows users to verify component operation and pinpoint the source of vehicle faults more accurately.

• 3 Essential Maintenance Functions

• EPB Reset: Retract and release the electronic parking brake, assist with brake pad replacement, and recalibrate the system after brake service.

• Oil Service Reset: Reset the oil life indicator and start a new service interval after an oil change.
• BMS Reset: Register a new battery with the vehicle after battery replacement to ensure proper charging management.

All-Systems Scan & Diagnostics:
- Echo performs comprehensive vehicle diagnostics across multiple control modules, allowing you to read and clear diagnostic trouble codes (DTCs), view live data, and access available service functions. It covers major vehicle systems such as:
- Engine, Transmission, ABS, Airbag, Immobilizer, Key Coding, Instrument Cluster, Steering, Suspension, TPMS, 4WD, Body Control, Doors, Seats, Air Conditioning, Electronic Parking Brake, Electric Power Steering, Throttle, Cruise Control, Parking Assist, Lighting, Wipers, Central Locking, Windows, Fuel System, DPF, Clutch, and more.
- Coverage varies by vehicle make, model, year, and system configuration.

Advanced Diagnostics:
Go beyond basic code reading with OE-level diagnostic capabilities. Echo provides deeper access to vehicle control modules and system data, helping identify hidden faults and providing more detailed information for troubleshooting and repair.
