The LAUNCH CReader 319 OBD2 scanner is a practical and user-friendly tool designed for DIY car enthusiasts and vehicle owners to easily diagnose engine problems. This handheld device allows you to read and clear engine error codes, view live data, and perform essential OBDII diagnostics, empowering you to understand your car’s health right in your garage. Let’s delve into the features and functionalities that make the CR319 a valuable addition to your automotive toolkit.
Key Functions of the LAUNCH CReader 319 OBD2 Scanner
The CReader 319 is packed with essential functions to help you maintain your vehicle’s engine efficiently:
1. Engine Code Reading and Clearing:
The primary function of the CR319 is to read diagnostic trouble codes (DTCs) that trigger your car’s ‘Check Engine’ light. It not only identifies the problem areas but also allows you to clear these codes after repairs, effectively turning off the Malfunction Indicator Lamp (MIL).
2. Live Data and Freeze Frame:
When an emission-related fault occurs, the CR319 captures crucial vehicle parameters in real-time and stores them as freeze frame data. This snapshot of data provides a detailed context of the engine’s condition at the moment the fault was detected, aiding in more accurate troubleshooting and repair.
3. I/M Readiness Status:
Ensure your vehicle is ready for emissions testing with the I/M Readiness feature. This function checks the status of emission-related systems, indicating whether they are operating correctly and prepared for Inspection and Maintenance (I/M) testing.
4. VIN Code Reading:
Quickly retrieve your Vehicle Identification Number (VIN) directly from the car’s ECU (Engine Control Unit). This feature simplifies vehicle identification and is essential for accessing vehicle-specific information and diagnostics. (Note: VIN reading capability depends on vehicle ECU support).
5. Reading Hard (Memory) and Pending Codes:
The CR319 can read both confirmed ‘hard’ codes stored in the ECU memory and ‘pending’ codes, which are intermittent faults that have not yet triggered the MIL. This comprehensive code reading capability provides a complete picture of your vehicle’s diagnostic status.
6. Oxygen (O2) Sensor Test:
Monitor your vehicle’s oxygen sensors with the dedicated O2 Sensor Test function. The CR319 allows you to retrieve and view O2 sensor monitor test results from the vehicle’s on-board computer, helping you assess sensor performance and identify potential issues.
7. On-Board Monitor Test:
Access the results of on-board monitor tests to evaluate the performance of various vehicle systems. These tests are particularly useful post-service or after clearing the vehicle’s control module memory, ensuring all systems are functioning as expected.
8. Vehicle Information Display:
Get essential vehicle details at your fingertips. The Vehicle Information option displays the VIN, calibration ID, calibration verification number (CVN), and other crucial information about the tested vehicle, ensuring you have the correct data for diagnostics and maintenance.
Comprehensive OBDII Diagnostic Modes
The LAUNCH CR319 supports all 10 modes of OBDII diagnostics, ensuring complete engine system analysis. Compatible with most OBDII/CAN protocol compliant vehicles from 1996 US-based, 2000 EU-based, and 2006 Asian cars, this tool provides technicians and DIYers with in-depth diagnostic capabilities:
