XMC 000709.21 – Steering Wheel Position Sensor Channel 2, Fault
XMC 000709.21 (XMC 709.21)
Code: 000709.21
Shortcode: 709.21
Description:
This error code is generated if the duty cycle at channel 2 of the steering wheel position sensor is less than 1%. Although the value measured by the XSC control software is within the acceptable range, such a low duty cycle may suggest a potential issue with the sensor or its signal processing.
Reaction:
When this error is detected, the control software will limit or disable certain functions to prevent potential malfunctions related to incorrect steering wheel position readings.
Recommendations:
Inspect Sensor Wiring:
- Check the wiring harness connected to the steering wheel position sensor for any signs of damage, disconnection, or corrosion. Repair or replace any damaged wiring.
Test Sensor Functionality:
- Use diagnostic tools to test the functionality of the steering wheel position sensor. Ensure it is operating within specified parameters.
Verify Sensor Mounting:
- Ensure the sensor is securely mounted and properly aligned. Loose or misaligned sensors can give inaccurate readings.
Check for Interference:
- Ensure there is no electrical interference affecting the sensor. Inspect nearby components for potential sources of interference.
Replace Faulty Sensor:
- If the sensor itself is determined to be faulty, replace it with a new, manufacturer-approved part.
Consult Technical Support:
- If the issue persists, consult technical support for further assistance.
Note:
Regular maintenance and inspection of sensors and their connections are crucial for reliable vehicle operation. Addressing issues promptly can prevent duty cycle-related problems from affecting system performance.
