1. What is EPS Calibration and Why is it Necessary?
EPS calibration is the process of resetting or adjusting the Electronic Power Steering system to ensure it functions correctly. This is necessary after certain repairs, such as replacing EPS components, performing wheel alignments, or any event that might affect the steering angle sensor. Without proper calibration, the EPS system might provide incorrect assistance, leading to handling issues or safety concerns.
EPS (Electronic Power Steering) calibration is essential for several reasons:
- Restoring Proper Functionality: Calibration ensures the EPS system functions according to the manufacturer’s specifications after repairs or component replacements.
- Ensuring Accurate Steering Assistance: Proper calibration guarantees the correct amount of steering assistance is provided, enhancing vehicle handling and driver control.
- Maintaining Safety: Accurate EPS calibration helps maintain vehicle stability and reduces the risk of accidents by ensuring the steering system responds correctly.
- Preventing Fault Codes: Calibration can resolve issues that trigger diagnostic trouble codes (DTCs) related to the EPS system, preventing warning lights and potential system malfunctions.
2. Which Car Scan Tools Can Perform EPS Calibration?
Not all car scan tools can perform EPS calibration. Basic OBD2 scanners generally lack the advanced functions required for this procedure. You’ll typically need a professional-grade scan tool or a factory-level diagnostic system. These advanced tools offer bidirectional control, allowing you to communicate with and adjust the EPS module.
Here’s a breakdown of the types of scan tools that typically support EPS calibration:
- Professional-Grade Scan Tools: These are mid-range to high-end scan tools used by automotive technicians. They often include bidirectional control, allowing communication with the EPS module.

11. Can a Car Scan Tool Reset the EPS Light?
Yes, a car scan tool can often reset the EPS (Electronic Power Steering) light after addressing the underlying issue. However, simply resetting the light without fixing the problem is not advisable. The EPS light indicates a fault in the system, and clearing it without proper diagnosis and repair can lead to safety risks. Here’s how a scan tool can be used to reset the EPS light:
- Diagnose the Issue:
- First, use the scan tool to read the Diagnostic Trouble Codes (DTCs) from the EPS module.
- Understand what each code means to identify the specific problem within the EPS system.
- Repair the Fault:
- Address the identified issue by repairing or replacing the faulty components, such as the steering angle sensor, torque sensor, or EPS motor.
- Ensure all connections are secure and wiring is intact.
- Clear the DTCs:
- Once the repair is complete, use the scan tool to clear the DTCs from the EPS module.
- This step turns off the EPS light on the dashboard.
- Verify the Repair:
- After clearing the codes, perform a test drive to ensure the EPS system is functioning correctly and the EPS light does not reappear.
- Monitor live data from the EPS module using the scan tool to confirm proper operation.
12. What Happens if the EPS Light Comes Back On?
If the EPS light reappears after being reset, it indicates that the underlying issue has not been fully resolved or a new problem has emerged. Here are the steps to take:
- Re-scan for DTCs:
- Use the scan tool to read the new DTCs from the EPS module.
- Note any differences from the previous codes to understand if it’s a recurring or new issue.
- Inspect the Repaired Components:
- Check the components that were previously repaired or replaced to ensure they are still functioning correctly.
- Look for any signs of damage or wear.
- Check Wiring and Connections:
- Inspect the wiring and connections related to the EPS system for any loose connections, corrosion, or damage.
- Ensure proper grounding for all components.
- Test the Steering Angle Sensor:
- Use the scan tool to monitor the steering angle sensor’s live data.
- Verify that the sensor is providing accurate readings as the steering wheel is turned.

- They can perform advanced diagnostics and use specialized tools to identify and resolve complex issues.
13. Can They Perform EPS Calibration or Reset Procedures After a Wheel Alignment?
Yes, performing EPS (Electronic Power Steering) calibration or reset procedures after a wheel alignment is often necessary. Wheel alignments can affect the steering angle sensor, which is a crucial component of the EPS system. Here’s why and how:
-
Why EPS Calibration is Needed After Wheel Alignment:
- Steering Angle Sensor (SAS) Calibration: During a wheel alignment, adjustments are made to the steering linkage. These adjustments can shift the center point of the steering wheel and affect the SAS, which provides data to the EPS module.
- Ensuring Accurate Steering Assistance: If the SAS is not properly calibrated after an alignment, the EPS system may provide incorrect steering assistance, leading to handling issues or a steering wheel that is not centered.
- Preventing Fault Codes: An uncalibrated SAS can trigger diagnostic trouble codes (DTCs) related to the EPS system, causing the EPS light to illuminate on the dashboard.
-
How to Perform EPS Calibration After Wheel Alignment:
- Use a Suitable Scan Tool: Ensure you have a professional-grade scan tool that supports EPS calibration for the specific vehicle make and model.
- Connect the Scan Tool: Plug the scan tool into the vehicle’s OBD2 port.
- Access EPS Functions: Navigate to the EPS module in the scan tool’s menu.
- Select SAS Calibration or Reset: Choose the appropriate function, which may be labeled “Steering Angle Sensor Calibration,” “SAS Reset,” or similar.
- Follow On-Screen Instructions:
- Carefully follow the scan tool’s on-screen prompts. This typically involves:
- Ensuring the steering wheel is centered.
- Driving the vehicle straight for a short distance.
- Turning the steering wheel to specific angles as directed by the scan tool.
- Verify Calibration: After the procedure, the scan tool may provide a confirmation message. Perform a test drive to ensure the EPS system is functioning correctly and the steering wheel is properly centered.
14. What Are the Risks of Not Calibrating EPS After a Wheel Alignment?
Failing to calibrate the EPS system after a wheel alignment can lead to several potential issues:
- Incorrect Steering Assistance: The EPS system might provide too much or too little assistance, making the vehicle harder to control.
- Off-Center Steering Wheel: The steering wheel might not be centered when driving straight, which can be annoying and lead to driver fatigue.
- Illuminated EPS Warning Light: The EPS warning light may come on, indicating a problem with the system and potentially causing the system to disable itself.
- Compromised Vehicle Stability: Incorrect EPS calibration can affect the vehicle’s stability control systems, reducing overall safety.
15. How Often Should EPS Calibration Be Performed?
EPS calibration should be performed:
- After Wheel Alignments: Anytime the wheel alignment is adjusted.
- After Replacing EPS Components: Whenever parts like the steering angle sensor, EPS motor, or EPS control module are replaced.
- After Suspension Work: If suspension components are replaced or adjusted, which can affect the steering geometry.
- When the EPS Warning Light Is On: After diagnosing and repairing the underlying issue that triggered the EPS warning light.
- As Part of Routine Maintenance: Some manufacturers recommend performing EPS calibration as part of routine maintenance, typically every 24,000 to 36,000 miles.
