3.1. Features and Functions

The KW310 is a professional car computer fault code reader that supports all OBD2 modes. Its features include:

  • Read/Clear Codes: Retrieves generic and manufacturer-specific Diagnostic Trouble Codes (DTCs) and clears them, turning off the Check Engine Light.
  • Live Data: Displays real-time sensor data from the vehicle's engine control unit (ECU).
  • Freeze Frame Data: Captures a snapshot of operating conditions at the moment a fault code is set.
  • I/M Readiness: Checks the status of emission-related monitors to ensure the vehicle is ready for an emissions test.
  • O2 Sensor Test: Retrieves O2 sensor monitor test results.
  • On-board Monitoring Test: Retrieves test results for emission-related powertrain components and systems.
  • EVAP System Test: Initiates a leak test for the vehicle's evaporative emission system.
  • Vehicle Information: Retrieves Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN).
  • Wide Vehicle Compatibility: Works on most 1996 and newer USA-based, European, and Asian gasoline or diesel vehicles (OBDII & CAN compliant).
