Key Features of the Autel MS309 OBD2 Scanner
This car engine fault code reader is packed with features to help you understand and address your vehicle’s issues efficiently.
Read and Clear DTCs
The primary function of the Autel MS309 is to read and clear DTCs. It can retrieve both generic and manufacturer-specific codes, providing a comprehensive diagnostic overview. The scanner displays the DTC and its definition directly on the screen, taking the guesswork out of interpreting fault codes. Once you’ve addressed the issue, the MS309 allows you to easily erase these codes and clear the check engine light.
On-Screen DTC Definitions
A standout feature of the MS309 OBD2 scanner is its on-screen DTC definitions. Instead of having to look up codes in a manual or online, the Autel MS309 displays the definition of the fault code right below the code itself. This immediate access to code meanings makes the diagnostic process faster and more user-friendly, especially for those new to car diagnostics.
Turn Off Check Engine Light (MIL)
The Autel MS309 car engine fault code reader is designed to help you tackle emission-related problems that trigger the check engine light (MIL). By reading and clearing these trouble codes, the MS309 can turn off the MIL and reset the monitor. This is particularly useful after performing repairs, allowing you to confirm that the issue is resolved and the warning light stays off.
Smog Check Readiness
Preparing for a smog check can be stressful. The MS309 OBD2 scanner helps alleviate this by retrieving I/M Readiness status. This feature checks various monitors, including the misfire monitor, fuel system monitor, and O2 sensors, ensuring your car is ready to pass the annual emissions test. By proactively checking your vehicle’s readiness, you can avoid unexpected failures during the smog check.
Retrieve Freeze Frame Data & Vehicle Info
For deeper diagnostics, the Autel MS309 can retrieve freeze frame data. This data captures a snapshot of critical engine parameters – such as RPM, fuel pressure, and engine coolant temperature – at the moment a fault code is triggered. This information can be invaluable in understanding the conditions under which the problem occurred. Additionally, the scanner retrieves essential Vehicle Information, including the VIN number, Calibration ID(s), and Calibration Verification Nos. (CVNs).
