CGSULIT SC301 Car Code Reader

Safety Precautions and Warnings

1. Always perform automotive testing in a safe environment.
2. Wear safety eye protection that meets ANSI standards.
3. Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts.
4. Operate the vehicle in a well-ventilated work area: Exhaust gases are poisonous.
5. Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
6. Use extreme caution when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components create hazardous voltages when the engine is running.
7. Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
8. Don’t connect or disconnect any test equipment while the ignition is on or the engine is running.
9. Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual transmission) and make sure the parking brake is engaged.
10. Keep the code reader dry, clean, and free from oil/water or grease. Use a mild detergent on a clean cloth to clean the outside of the code reader, when necessary.

General Information of OBDIL (On-Board Diagnostics II)

The OBDIl system is designed to monitor emission control systems and key engine components by performing either continuous or periodic tests of specific components and vehicle conditions, which will offer three pieces of such valuable information:

1. Whether the Malfunction Indicator Light (MIL) is commanded “on” or “off”;
2. Which, if any Diagnostic Trouble Codes (DTCs) are stored;
3. Readiness Monitor status.
