The LAUNCH Creader 319 Obd2 Scanner is designed as a user-friendly, entry-level tool for diagnosing engine-related issues in your vehicle. This DIY OBDII scanner empowers car owners to read and clear engine error codes, understand live data, and perform essential OBDII functions without needing professional mechanic assistance for basic diagnostics. Let’s delve into the features and functionalities that make the CR319 a valuable tool for car maintenance.
Key Features and Functions of the CR319 OBD2 Scanner
The LAUNCH CReader 319 is equipped with a range of functions to help you understand your vehicle’s engine health. Here are the core capabilities:
Read and Clear Engine Error Codes
The primary function of the CR319 is to read diagnostic trouble codes (DTCs) that trigger the ‘Check Engine’ light. Understanding these codes is the first step in diagnosing engine problems. The scanner not only reads these codes but also allows you to clear them after repairs are made, effectively turning off the Malfunction Indicator Lamp (MIL), commonly known as the ‘Check Engine’ light. This helps confirm if the issue is resolved and if the light was not triggered by a transient problem.
Live Data and Freeze Frame
The CR319 provides access to live data streams from your vehicle’s engine. This real-time information includes sensor readings, engine speed (RPM), coolant temperature, and more. Alongside live data, the freeze frame feature captures a snapshot of critical vehicle parameters at the exact moment an emission-related fault occurs. This freeze frame data provides valuable context, helping to pinpoint the conditions under which a problem arose, thus aiding in more effective troubleshooting and repair.
I/M Readiness Status
The I/M Readiness feature is crucial for vehicle emissions testing. It checks the status of various emission-related systems in your car, indicating whether they are operating correctly and ready for Inspection and Maintenance (I/M) testing. This function helps you proactively ensure your vehicle will pass emissions tests, avoiding potential failures and the need for re-testing.
VIN Code Reading
The Vehicle Identification Number (VIN) is your car’s unique fingerprint. The CR319 can read the VIN code directly from the car’s ECU (Electronic Control Unit). While not all ECUs support this function, when available, it automatically retrieves this crucial information, which can be useful for vehicle identification and accessing vehicle-specific data.
Oxygen Sensor Test
Oxygen sensors are vital for monitoring the air-fuel mixture in your engine and ensuring efficient combustion and emissions control. The CR319 allows you to retrieve and view the results of oxygen sensor monitor tests. This function helps assess the performance of your O2 sensors, which is critical for fuel efficiency and emissions compliance.
On-Board Monitor Test
The On-Board Monitor test function allows you to view the results of diagnostic tests for specific vehicle systems performed by the vehicle’s computer itself. These tests are particularly useful after servicing or clearing the vehicle’s control module memory. They confirm that on-board diagnostic systems are functioning correctly post-repair or reset.
Vehicle Information
Beyond the VIN, the Vehicle Information function provides access to other important vehicle details, including calibration identification and calibration verification numbers (CVN). This information can be useful for ensuring correct software versions and compatibility, especially when performing more advanced diagnostics or reprogramming.
Comprehensive OBDII Diagnostic Modes
The CR319 supports all 10 modes of OBDII diagnostics. These modes cover a wide spectrum of diagnostic requests, allowing technicians and DIY users to access detailed information about the vehicle’s powertrain and emission control systems. These modes include:
- Mode 01: Request current powertrain diagnostic data.
- Mode 02: Request freeze frame information.
- Mode 03: Request emission-related diagnostic trouble codes.
- Mode 04: Clear/reset emission-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 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 emission-related diagnostic trouble codes with permanent status after a clear/reset emission-related diagnostic information service.
Built-in DTC Lookup Library
One of the most convenient features of the CR319 is its integrated DTC lookup library. Instead of having to search online for code definitions, you can simply input the error code directly into the scanner, and it will provide the definition on the screen. This saves time and makes the diagnostic process more efficient for users of all skill levels.
Multi-Language Support
The CR319 caters to a global audience by supporting multiple languages, including English, French, Russian, Spanish, German, Italian, and Portuguese. Changing the language is straightforward through the tool setup menu, making it accessible to a wider range of users.
Broad Vehicle Compatibility
The LAUNCH CR319 is designed to work with most OBDII compliant vehicles. This includes:
- American Cars: Standard OBD2 protocols from 2000 onwards (Chrysler, Ford, GM, Jeep, etc.).
- European Cars: Standard OBD2 protocols from 2003 onwards (Alfa Romeo, BMW, Mercedes-Benz, VW, etc.).
- Japanese/Korean Cars: Standard OBD2 protocols from 2006 onwards (Honda, Toyota, Nissan, Hyundai, KIA, etc.).
- Chinese Cars: Standard OBD2 protocols from 2009 onwards.
It’s important to note that while the CR319 is compatible with a vast majority of vehicles within these ranges, OBD2 protocol support adoption varied by region and manufacturer. Some vehicles, even within these date ranges, may not fully support OBD2 protocols or have specialized systems. The CR319 supports a wide array of OBD2 protocols ensuring compatibility with a broad range of vehicles:
- SAE J1850 PWM
- SAE J1850 VPW
- ISO9141-2
- ISO14230-4 KWP
- ISO15765-4 CAN
User-Friendly Operation
Using the LAUNCH CR319 is designed to be simple and intuitive. It’s a plug-and-play device that requires no batteries or external apps.
- Simply plug the CR319 into your car’s 16-pin OBD2 port, typically located under the dashboard.
- Turn on the ignition – no need to start the engine, just turn the key to the ‘ON’ position.
- Select the desired diagnostic function from the menu displayed on the scanner.
The CR319 draws power directly from the vehicle’s OBD2 port, eliminating the need for batteries and making it instantly ready to use.
This tool is designed for quick diagnostics without the need for software updates, making it a convenient tool to have in your glove compartment. Its user-friendly interface and included manual ensure even those with minimal diagnostic experience can effectively use the CR319 to understand their vehicle’s health.
Compact and Portable Design
The CR319’s small size makes it easy to handle and store. Its compact design means it won’t take up much space in your car, allowing you to keep it readily available for whenever you need to perform a quick diagnostic check.
