• Vehicle Information Access: Easily retrieve essential vehicle information such as VIN (Vehicle Identification Number), CID, and CVN. This simplifies vehicle identification and helps in tracking vehicle history and records.
• Built-in DTC Lookup: No need to search online for code definitions. The integrated DTC lookup library provides detailed explanations for diagnostic trouble codes directly on the device, saving you valuable time and effort.
• Multilingual Support: Operate the CR319 in your preferred language. It supports English, Portuguese, Russian, Italian, Spanish, French, and German menus, enhancing user accessibility.

Comprehensive OBDII Test Modes for Full Car Diagnostics

The LAUNCH code reader CR319 offers complete OBD2 testing capabilities, making it an indispensable tool for car owners who want to stay ahead of potential car problems. By providing access to all 10 OBDII test modes, this scanner helps you proactively manage your vehicle’s health, reducing unexpected repair costs and downtime.

1. Read and Erase Fault Codes: Identify the diagnostic trouble codes (DTCs) that trigger the Check Engine Light, pinpointing the source of the problem. Clear these codes after performing repairs to switch off the warning light.
2. Turn off Check Engine Light (MIL): Deactivate the Malfunction Indicator Lamp (MIL) on your dashboard after addressing the underlying issues and clearing the corresponding DTCs.
3. Live Data Stream Display: Monitor real-time operating parameters of your vehicle’s engine and related systems. Analyze dynamic data to understand engine performance and identify anomalies.
4. I/M Readiness Status: Check the Inspection and Maintenance Readiness status to determine if your vehicle is ready for emission testing. This feature verifies the status of emission-related systems.
5. Freeze Frame Data: Display freeze frame data, which records critical parameters when an emission-related fault occurs. This snapshot helps diagnose the conditions present when the fault code was set.
6. O2 Sensor Test: Evaluate the performance of your vehicle’s oxygen sensors. This test is vital for monitoring fuel efficiency and emission control system effectiveness.
7. EVAP System Test: Perform an EVAP (Evaporative Emission Control System) test to check for leaks in the fuel tank system and carbon canister, contributing to environmental protection.
8. On-board Monitor Test: Access the results of on-board diagnostic monitoring tests for specific components or systems. This feature assesses whether monitors are functioning within normal parameters.
9. Vehicle Information Retrieval: Obtain vehicle information including VIN (Vehicle Identification Number), CID, and CVN. Accessing this data aids in vehicle identification and tracking of historical records.
10. DTC Lookup Library: Utilize the built-in DTC lookup library to read both generic (P0, P2, P3, and U0) and manufacturer-specific (P1, P3, and U1) codes. The tool directly displays code definitions, eliminating the need for online searches.

Read and Erase DTCs – Take Control of Your Check Engine Light

The LAUNCH CR319 empowers you to read diagnostic trouble codes (DTCs) that activate your Check Engine Light, revealing the root cause of the malfunction. This early detection can help identify issues like engine misfires before they lead to more significant damage. After completing necessary repairs, you can confidently use the CR319 to clear these codes and turn off the Check Engine Light, ensuring your dashboard is free of unnecessary warnings.

I/M Readiness Check – Ace Your Smog Test with Confidence

The I/M Readiness Test, a key function of the LAUNCH OBD2 code reader CR319, simplifies smog test preparation. This self-check routine evaluates emission-related sensors, providing a clear indication of whether your vehicle is likely to pass an emissions test. By checking I/M readiness, you can proactively address any potential emission issues and approach your smog test with confidence, avoiding unexpected failures.

O2 Sensor Test – Optimize Fuel Efficiency and Reduce Emissions

If you’ve noticed a decrease in your fuel mileage, the LAUNCH CR319 scan tool can help diagnose potential O2 sensor issues. The O2 Sensor Test allows you to check if your oxygen sensors are functioning correctly. Replacing a faulty O2 sensor can prevent damage to the catalytic converter, a costly repair that can be avoided with timely diagnosis and maintenance facilitated by the CR319.

Built-in DTC Library – Instant Code Definitions at Your Fingertips

When a diagnostic trouble code appears, the LAUNCH CR319 instantly displays its description, streamlining the diagnostic process. The integrated DTC lookup library means you don’t need to spend time searching for code meanings online. This feature provides quick and easy access to code definitions, helping you understand the problem and its potential solutions directly from the device.

Access VIN, CID, CVN – Vehicle History at Your Command

The CR319 OBD2 scanner allows you to access a wealth of vehicle information, including the Vehicle Identification Number (VIN), CID, and CVN. This capability is particularly useful when purchasing a used car, enabling you to easily track the vehicle’s history, verify mileage, and potentially avoid purchasing a vehicle with hidden problems or “lemon” status.

Live Data Stream – Real-time Insights into Your Engine’s Performance

The live data stream feature of the LAUNCH CR319 provides a real-time view of what your car’s Powertrain Control Module (PCM) is receiving from various sensors as the engine runs. Parameters such as RPM, fluid temperatures, and fuel injection data are displayed, offering valuable insights for diagnostics in various situations. For example, if you are investigating reduced fuel efficiency, live data can help pinpoint the contributing factors.

Freeze Frame Data – Pinpoint Issues with Snapshot Diagnostics

The OBD2 scanner CR319 captures freeze frame data, recording a snapshot of critical parameters at the moment a fault code is triggered. This data includes essential information like engine RPM, vehicle speed, airflow, engine load, and fuel pressure. Freeze frame data allows you to understand the exact conditions and sensor readings when a fault occurred, significantly aiding in accurate and efficient troubleshooting.
