EchoTub OBD2 Scanner S2 — compact car code reader, 2.8" colour display & 117 live parameters

The EchoTub OBD2 Scanner S2 is a compact plug-and-play code reader that reveals engine fault codes, shows up to 117 live parameters, and runs advanced Mode 6/8 and O2 sensor tests without apps or subscriptions.

Compact and user-friendly, the EchoTub S2 is designed for DIY mechanics and technicians who need solid diagnostic capability without extra software. Its bright 2.8-inch color display, broad protocol support, and thirteen built-in functions give you clearer data and deeper insight than most entry-level scanners. The unit connects directly to any OBD-II/EOBD-compliant gasoline car (1996+ US, 2000+ EU, 2005+ Asia) and operates right from the vehicle’s diagnostic port.

What can this scanner read and clear?

The S2 reads generic and manufacturer-specific DTCs and lets you clear trouble codes after repairs. It also stores freeze-frame snapshots and includes an on-device DTC library to help interpret codes quickly.

• Read and erase stored and pending DTCs
• Freeze Frame captures engine conditions when a fault occurred
• Built-in DTC library and playback to review past sessions

How does the S2 help diagnose emissions and fuel issues?

Beyond basic code reading, the S2 offers Mode 6, Mode 8, and oxygen sensor testing so you can identify failing components before a check-engine light or a failed smog inspection. The I/M Readiness quick-check and dedicated hot key let you confirm monitors are complete before a test.

• Mode 6 shows component test results to find marginal parts
• Mode 8 supports EVAP vapor leak checks for emissions troubleshooting
• O2 sensor test and a BAT key for quick 12V battery checks

What live data and vehicle compatibility does it support?

The S2 displays up to 117 live data items including RPM, coolant temperature, fuel trims, and more — far more parameters than typical budget scanners. It supports all nine OBD-II/EOBD/CAN protocols so it will work with nearly every gasoline vehicle meeting OBD-II standards.

• Live data stream up to 117 items for real-time troubleshooting
• Supports 9 OBD-II/EOBD/CAN protocols for wide vehicle coverage
• Plug-and-play — no batteries, Bluetooth, apps, or subscriptions

How easy is it to use and what languages are available?

The S2 is designed for immediate use: plug it into the OBD-II port and turn the ignition. A bright color TFT makes menus and live-data graphs easier to read than monochrome alternatives, and menu options are available in nine languages.

• 2.8" color TFT (240×320) for clearer on-device readouts
• 9 interface languages including English, Spanish, French, and German
• CE, FCC, and RoHS certifications for safety and compliance

Who is this for? The EchoTub S2 is ideal for DIY car owners, home mechanics, and technicians who want more diagnostic depth than a basic $30 reader without the complexity of software-dependent tools. It’s best for gasoline vehicles that meet OBD-II/EOBD standards — not suitable for diesel, hybrid, or electric vehicles. If you want a durable, standalone scanner with advanced emission tests and extensive live data, the S2 balances capability and ease-of-use in a compact handheld package.
