2. Initial Setup
The CGSULIT SC850 is designed for plug-and-play operation, requiring minimal setup before first use. Follow these steps to begin diagnostics:
- Connect the Diagnostic Cable: Locate your vehicle's 16-pin OBDII diagnostic port, typically found under the dashboard on the driver's side. Plug the diagnostic cable from the SC850 scanner firmly into this port. The device will power on automatically, drawing power directly from the vehicle's OBDII port.
- Turn on Vehicle Ignition: Turn your vehicle's ignition key to the "ON" position (engine off). For push-button start vehicles, press the start button without pressing the brake pedal to turn on the ignition.
- Select Diagnostic Menu: Once the scanner powers on and initializes, navigate the main menu using the device's buttons. Select the "Diagnostic" option to begin scanning your vehicle's systems.

3. Operating the SC850 Scanner
3.1. 4-System Diagnostic Capabilities
The SC850 provides in-depth diagnostics for the four most common vehicle systems, allowing you to read and clear fault codes, view live data, and pinpoint issues within these critical areas:
- Engine System: Diagnose issues related to engine performance, emissions, and check engine light (MIL).
- Anti-lock Braking System (ABS): Identify problems with the ABS, including sensor failures and brake system warnings.
- Supplemental Restraint System (SRS/Airbag): Check for faults in the airbag system and related components.
- Transmission System: Diagnose issues affecting gear shifting, transmission fluid, and overall transmission performance.
