After repairs on my 2011 Kia Sorento, I used the Autel MaxiCOM MK808Z to fix persistent ESP and Downhill Assist lights that a professional shop couldn't solve. The tool accurately identified a calibration error that was causing the warning lights, proving its value for home diagnostics.
This guide shares my experience using the Autel MK808Z to perform a professional-grade Steering Angle Sensor (SAS) calibration. By following these steps, you can save on dealership fees and ensure your vehicle’s safety systems are correctly reset.
1. Preparation and Connection
Before starting, ensure your vehicle is parked on flat ground and your tire pressure is correct.
(1) Plug in the Tool: Connect the Autel MK808Z to the OBDII port located under the dashboard.
(2) Power On: Turn the ignition to the ON position without starting the engine.
(3) Vehicle ID: Select Diagnostics and use Auto Detect to identify the 2011 Kia Sorento.
2. Diagnose the Fault
Verify the sensor data before attempting a reset to confirm the calibration error.
(1) Check Codes: Navigate to the ESP unit to find codes such as "Steering Angle Sensor Circuit".
(2) View Live Data: Access the "Steering Sensor" data stream to see the current degree reading.
(3) Verify Error: If the wheel is centered but the tool reads a value like 360° instead of 0°, calibration is required.
3. SAS Calibration Procedure
(1) Enter Hot Functions: From the main menu, select Hot Functions > Steering Angle Sensor (SAS).
(2) Center the Wheel: Physically place the steering wheel in the center position.
(3) Initiate Reset: Follow the prompts and press Reset while the ignition is in the ON position.
(4) Cycle Ignition: Once "Reset Complete" appears, turn the ignition OFF for 10 seconds.
(5) Finish: Turn the ignition back ON and press OK to finalize the process.
4. Results
- Lights Clear: After starting the engine, the ESP and Downhill warning lights should be off.
- Successful Fix: The Autel MK808Z provides an easy and effective way to handle SAS resets that some shops might overlook.
