Is your car’s check engine light on? Don’t panic and rush to an expensive mechanic right away. The LAUNCH CReader 319 OBD2 Scanner is a user-friendly, handheld tool designed to help you understand and address common engine problems yourself. This DIY OBDII scanner empowers car owners and enthusiasts to read and clear engine error codes, check emission readiness, and access vital vehicle data, all from the comfort of their garage.
The CReader 319 is more than just a basic code reader. It provides a range of functions to help you diagnose your vehicle’s health effectively. Let’s explore the key features that make this scanner a valuable addition to your automotive toolkit.
Key Features of the LAUNCH CReader 319
This compact OBD2 scanner is packed with features to assist in diagnosing engine-related issues:
1. Read and Clear Engine Error Codes: The primary function of the CReader 319 is to read diagnostic trouble codes (DTCs) that trigger the check engine light. It not only reads these codes but also allows you to clear them after repairs are made, turning off the annoying ‘Engine Check’ MIL (Malfunction Indicator Lamp).
2. Live Data and Freeze Frame: When an emission-related fault occurs, the CReader 319 captures a snapshot of critical vehicle parameters known as “Freeze Frame” data. This function records specific vehicle conditions at the moment of the fault, such as engine speed, coolant temperature, and fuel trim, helping you pinpoint the problem’s context and location for more efficient repairs. Additionally, the live data stream displays real-time sensor information, allowing you to monitor your vehicle’s operation as it runs and identify intermittent issues.
3. I/M Readiness Status: Before heading for a smog check or emissions test, use the I/M Readiness function. This feature checks if your vehicle’s emission systems are ready for inspection and maintenance testing. It indicates whether essential systems like the catalytic converter, oxygen sensors, and evaporative system are functioning correctly, saving you time and potential failures during official inspections.
4. VIN Code Reading: The Vehicle Identification Number (VIN) is your car’s unique fingerprint. The CReader 319 can read the VIN code directly from the car’s ECU (Engine Control Unit). This is useful for vehicle identification, accessing vehicle-specific information, and ensuring you are working with the correct vehicle data. (Note: VIN reading function depends on vehicle ECU support).
5. Reading Hard (Memory) Codes and Pending Codes: The scanner reads both confirmed “hard” codes stored in the ECU’s memory and “pending” codes. Pending codes indicate intermittent issues that haven’t yet triggered the check engine light but could become permanent problems. Identifying pending codes early can help prevent more significant repairs down the line.
6. Oxygen (O2) Sensor Test: Oxygen sensors are crucial for monitoring exhaust emissions and ensuring optimal fuel efficiency. The CR319 allows you to retrieve and view O2 sensor monitor test results directly from your vehicle’s computer. This data helps assess the performance of your O2 sensors, which is vital for both engine performance and environmental compliance.
7. On-Board Monitor Test: This function allows you to access the results of on-board diagnostic monitoring tests for specific vehicle systems. These tests are often performed by the vehicle’s computer after servicing or clearing the ECU memory to ensure systems are functioning correctly post-repair.
8. Vehicle Information Display: Beyond the VIN, the CReader 319 can display other important vehicle information, including calibration IDs (calibration identification) and CVNs (calibration verification numbers). This data is useful for verifying software versions and ensuring compatibility when performing diagnostics or software updates.
Comprehensive OBDII Diagnostics – All 10 Modes Supported
The LAUNCH CReader 319 OBD2 Scanner is designed to support all 10 modes of OBDII diagnostics, ensuring comprehensive engine system analysis. This tool is compatible with most OBDII/CAN protocol compliant vehicles manufactured from 1996 in the US, 2000 in Europe, and 2006 in Asia. It retrieves engine-related trouble codes from the Vehicle ECU, performs I/M monitor readiness tests, displays live data streams, shows freeze frame data, and offers code reading and clearing capabilities. Here’s a breakdown of the 10 OBDII modes supported:
- Mode 01: Request current powertrain diagnostic data.
- Mode 02: Request freeze frame information.
- Mode 03: Request emissions-related diagnostic trouble codes.
- Mode 04: Clear/reset emissions-related diagnostic information.
- Mode 05: Request oxygen sensor monitoring test results.
- Mode 06: Request on-board monitoring test results for specific monitored systems.
- Mode 07: Request emission-related diagnostic trouble codes detected during the current or last completed driving cycle.
- Mode 08: Request control of on-board system, test, or component.
- Mode 09: Request vehicle information.
- Mode 10: Request emissions-related diagnostic trouble codes with permanent status after a clear/reset.
Built-in DTC Lookup Library
Forget searching online for error code definitions! The CR319 features a convenient built-in DTC lookup library. Simply navigate to the DTC Lookup menu, enter the error code, and the scanner will display the definition right on the screen. This saves you time and eliminates the hassle of manual code lookups.
