CGSULIT OBD2 Scanner SC103, 2.8-inch Colour Screen — Live Data, I/M Readiness & DTC Reader

The CGSULIT SC103 is a plug-and-play OBD2 code reader that identifies and clears engine fault codes, shows live engine data, and performs I/M readiness checks for vehicles since 1996.

If you want a straightforward diagnostic tool that fits in the glovebox and provides more insight than a basic code reader, the SC103 blends an easy setup with professional features. It works with all OBDII-compliant cars, light trucks, and SUVs, supports every common protocol, and displays results on a bright 2.8-inch color screen. With a built-in code library, freeze-frame capture, and battery voltage test, it helps you decide whether a home repair is possible or a trip to the shop is needed.

How does the SC103 help me diagnose a check engine light?

The SC103 reads and clears Diagnostic Trouble Codes (DTCs) and shows freeze-frame data so you can see engine conditions at the moment a fault was recorded. Clearing codes can verify temporary issues or confirm recurring problems. The unit also includes a local DTC library to explain codes without needing a phone.

• Reads and erases generic and manufacturer DTCs
• Freeze-frame capture shows snapshot of engine conditions
• Built-in DTC definitions to interpret codes offline
• I/M readiness monitors to prepare for smog checks

What live data and tests can I view with this scanner?

Real-time engine parameters are available as both numbers and graphs, so you can watch changes while the engine runs. Common PIDs like RPM, vehicle speed, coolant temperature, and fuel system status are included. There’s also a battery voltage readout to quickly assess charging system health.

• Live stream: RPM, speed, coolant temp, and more
• Graphical display for trend spotting and anomalies
• Battery voltage test for alternator/battery diagnostics
• Freeze-frame data for post-fault analysis

Which vehicles are compatible and how do I use it?

The SC103 supports all five major OBDII protocols so it connects to virtually every OBDII-equipped vehicle sold in the U.S. since 1996, many European vehicles since 2003, and most Asian vehicles since 2008. Use is simple: plug the unit into the vehicle’s OBD2 port—no batteries required—and follow the menu to scan or view live data.
