Does your car have those problems?



Why We Need LAUNCH CR3008 OBD2 Scanner?


LAUNCH CR3008 obd2 code scanner can read and erase codes which can also retrieve a wealth of information from the Engine Control Unit (ECU). The ECU is what triggers the Check Engine Light when there is a problem with your car. Parts that might cause your check engine light on include:

#1. Gas Cap #2. Oxygen Sensor #3. Air Fuel Ratio Sensor #4. Mass Air Flow Sensor #5. Ignition Coils #6. Spark Plug Wires #7. Spark Plugs #8. Thermostat #9. EGR Valve #10. Evaporatative Emission Canister Purge Valve(EVAP) #11. Catalytic Converter.

And LAUNCH CR3008 obd2 code reader will read codes indicating these fault parts. After the car problems have been solved, the LAUNCH CR3008 car code reader can erase these trouble codes and turn off the check engine light.

Full OBD2 Check--Make a Better Detection for Car Engine System!

This scanner supports all 10 test modes for OBD-II cars which are great for daily repair work. The table below describes the purpose of each mode of operation:

1. Reading Codes: Show the detailed description of the Diagnostic Trouble Code (DTCs)

2. Erasing Codes & Reset: Turns off Check Engine Light (MIL), clears codes, and resets monitors.

3. Data Stream: Reads and displays live ECU/PCM data stream, plotting functions graphically and storing freeze frame data.

4. I/M Readiness Status: This shows whether the various emissions-related systems on the vehicle are operating properly and are ready for inspection and maintenance testing.

5. Read Live Data Stream: Show the information of continuous data stream from a vehicle in a live graphic (waveform) display.

6. View Freeze Frame Data: Check the certain vehicle conditions which are recorded by the onboard computer at the time the emission-related fault occurs.

7. O2 Sensor Test: Allows retrieval and viewing of O2 sensor monitor test results for the most recently performed tests from the vehicle’s onboard computer.

8. On-Board Monitor Test: Retrieves and displays test results for emission-related powertrain components and systems.

9. Read Vehicle Information: Display the information such as VIN (Vehicle Identification Number), CID (Calibration ID) and CVN (Calibration verification number), etc.

10. Component Test: Certain vehicle components can be actuated by commands sent from the scanner to test their operability.

On-board Monitor Test

Retrieves and displays test results for emission-related powertrain components and systems. This is a way to find out if the engine has any misfire or compression problems on a particular cylinder or other data that might indicate a problem but isn’t severe enough to trigger a check engine light.

I/M One-Key Fast Check (Smog-Check)

Quick state emissions readiness check and drive cycle verification.
