2. Understanding OBDII and CAN Protocols
2.1 What is OBDII?
On-Board Diagnostics II (OBDII) is a standardized system used in most vehicles since 1996 to monitor and report on the vehicle’s performance. According to the Environmental Protection Agency (EPA), OBDII systems were mandated to ensure vehicles meet emissions standards and to provide technicians with a way to diagnose issues quickly. The OBDII system uses a standardized connector (SAE J1962) and a set of diagnostic trouble codes (DTCs) to identify problems.
2.2 What is CAN Protocol?
Controller Area Network (CAN) is a robust communication protocol used in vehicles to allow various electronic control units (ECUs) to communicate with each other without a host computer. CAN bus systems improve efficiency and reliability in modern vehicles. As reported in Bosch Automotive Handbook, CAN protocol enables seamless data exchange between different parts of the vehicle.
2.3 Why are OBDII and CAN Important?
OBDII and CAN protocols are essential for modern vehicle diagnostics. OBDII provides a standardized way to access diagnostic information, while CAN facilitates communication between vehicle systems. These technologies enable tools like the MS309 to accurately diagnose issues and provide valuable insights into vehicle health.

3. Key Features of the CAN OBDII Car Scanner Tool MS309
The CAN OBDII car scanner tool MS309 is packed with features designed to make vehicle diagnostics simple and efficient.
3.1 Reading and Clearing DTCs
The MS309 can read both generic (P0, P2, P3, and U0) and manufacturer-specific (P1, P3, and U1) Diagnostic Trouble Codes (DTCs). It displays the DTCs and their definitions on the screen, helping you understand the nature of the problem. The tool also allows you to clear these codes, turning off the Check Engine Light (MIL) and resetting monitors.
3.2 On-Screen DTC Definitions
One of the standout features of the MS309 is its ability to display DTC definitions directly on the screen. This eliminates the need to search online or consult a manual to understand what each code means. The on-screen definitions provide a quick and easy way to diagnose issues.
3.3 Turning Off the Check Engine Light
The Check Engine Light (MIL) can be triggered by various issues, from minor problems like a loose gas cap to more serious engine malfunctions. The MS309 allows you to read and clear the codes that trigger this light, helping you determine if the problem is resolved or requires further attention. According to a study by the National Institute for Automotive Service Excellence (ASE), addressing issues promptly can prevent more extensive damage.
3.4 Smog Check Readiness
Many states require vehicles to pass a smog check to ensure they meet emissions standards. The MS309 can retrieve I/M Readiness status, allowing you to check the monitors like misfire monitor, fuel system monitor, and O2 sensors. This helps you ensure your car is ready to pass the annual smog check.
3.5 Freeze Frame Data and Vehicle Information Retrieval
The MS309 can retrieve freeze frame data, which includes important engine parameters like RPM, fuel pressure, and engine coolant temperature at the time a DTC was set. This information can be invaluable in diagnosing intermittent issues. Additionally, the tool can retrieve Vehicle Identification Number (VIN), Calibration ID(s), and Calibration Verification Numbers (CVNs).
3.6 Compatibility with 99% of Vehicles
The Autel MaxiScan MS309 supports all OBDII protocols: KWP2000, ISO2000, ISO9141, J1850 VPW, J1850 PWM, and CAN. This broad compatibility means it works on 99% of vehicles, including domestic, Asian, and European models from 1996 and newer.
