Understanding the Autel MaxiScan MS309’s Capabilities
The MS309 offers a wide array of features that simplify the vehicle diagnostic process. Let’s explore its key functionalities:
Read and Clear DTCs:
The core function of the MS309 is to read and clear generic and manufacturer-specific DTCs. It displays both the code and its definition, eliminating the need for separate lookups. This allows users to quickly identify the root cause of a check engine light or other vehicle malfunction. After resolving the issue, the MS309 can erase the DTCs and reset the check engine light.
On-Screen DTC Definitions:
The MS309 provides on-screen DTC definitions, directly below the retrieved code. This eliminates the need for external resources or code books, saving time and effort in diagnosing issues.
Turn Off Check Engine Light:

Smog Check Readiness:
The MS309 can retrieve the I/M Readiness status, indicating if the vehicle’s emission system monitors are functioning correctly. This information is crucial for passing smog checks, as it verifies the readiness of components like the misfire monitor, fuel system, catalyst, and O2 sensors.
Freeze Frame Data and Vehicle Information:
This scanner can capture freeze frame data, providing a snapshot of the engine’s parameters at the moment a DTC was triggered. This data includes vital metrics such as RPM, fuel pressure, and coolant temperature, aiding in pinpointing the problem’s source. Additionally, it retrieves vehicle information like the VIN, Calibration ID, and CVNs.
