After performing a steering calibration on a 2021 Seat Ibiza using VCDS, a reset of the software end-stop (IDE06133) resulted in multiple fault codes and a vehicle unsafe for road use. The issue stems from the inability to relearn the steering end stops after the reset. This article explores the problem, focusing on the “Steering End Stops Not Learned C10AC F0” error and potential solutions using an Autel diagnostic tool.
Understanding the C10ACF0 Fault Code
The C10ACF0 fault code, “Steering End Stops Not Learned,” specifically indicates that the steering angle sensor has not learned the limits of the steering rack’s travel. This is crucial for several safety and driver-assistance systems, including:
- Electronic Stability Control (ESC): Accurate steering angle input is essential for ESC to function correctly.
- Lane Keeping Assist (LKA): Knowing the steering wheel’s position helps LKA determine if the vehicle is unintentionally drifting out of its lane.
- Park Assist: This feature relies on precise steering angle information for automated parking maneuvers.
Without properly learned end stops, these systems may malfunction or become disabled entirely, as evidenced by the numerous fault codes logged in the VCDS scan. The scan revealed related errors in modules controlling the engine, ABS brakes, park assist, adaptive cruise control, and airbags, all stemming from the initial steering angle sensor issue.
Resolving C10ACF0 with Autel
While the original attempt to relearn end stops using common methods like full left and right turns proved unsuccessful, an Autel diagnostic scanner offers a more systematic approach. Autel devices, known for their comprehensive diagnostic capabilities, provide guided procedures for performing steering angle sensor calibrations and end stop learning.
Here’s a general outline of how an Autel scanner might be used to address the C10ACF0 error:
- Vehicle Identification: Connect the Autel scanner to the vehicle’s OBD-II port and accurately identify the make, model, and year. This ensures the correct procedures are loaded.
- Fault Code Reading: Read the fault codes stored in the various modules, confirming the presence of C10ACF0 and any related errors.
- Special Functions: Access the “Special Functions” menu on the Autel scanner. Look for options related to steering angle sensor calibration or “Steering Angle Sensor Reset/Calibration/End Stop Learning.”
- Guided Procedure: Follow the on-screen instructions provided by the Autel scanner. This typically involves turning the steering wheel to specific positions or driving the vehicle under certain conditions. The Autel device will guide you through each step.
- Fault Code Clearing: After completing the procedure, clear all fault codes related to the steering angle sensor.
- Verification: Verify the repair by test driving the vehicle and ensuring all affected systems are functioning correctly and no warning lights are illuminated. Re-scan for fault codes to confirm the issue is resolved.
Conclusion
Incorrectly resetting the software end-stop on a 2021 Seat Ibiza led to a cascade of fault codes and rendered the vehicle unsafe. Utilizing an Autel diagnostic scanner with its guided procedures for steering angle sensor calibration and end stop learning offers a targeted solution for resolving the C10ACF0 error and restoring proper vehicle functionality. The Autel’s ability to provide step-by-step instructions simplifies the process and increases the likelihood of a successful repair.
