There isn’t a simple reset button for these warnings. You typically diagnose the fault with a scan tool, fix the underlying issue, clear the codes, and drive the car to allow the system to relearn.
The following guide explains what triggers the Service AdvancTrac and Power Steering messages on a 2011 Ford Fusion, plus steps you can take at home and when you should seek professional service.
Understanding AdvancTrac and electric steering in the Fusion
The 2011 Ford Fusion uses Ford’s AdvancTrac stability control system alongside an electric power-steering system (EPAS). A fault in either system will often illuminate a “Service” message on the dash. Clearing the warning usually requires diagnosing and repairing the fault, then clearing codes with a proper scan tool and performing a drive cycle to let the system re-learn.
AdvancTrac service warning: what to check
Common causes of the AdvancTrac service warning include faulty wheel-speed sensors, steering-angle sensor issues, yaw-rate sensor problems, wiring or connector faults, and electrical issues or low battery voltage. Checking these areas first can help identify the root cause before replacing parts.
- Inspect tires for proper size, matching tread, and correct inflation; mismatched tires or incorrect pressures can affect wheel-speed data and trigger stability warnings.
- Scan for diagnostic trouble codes (DTCs) with a capable OBD-II tool or Ford IDS to identify wheel-speed, yaw-rate, steering-angle, ABS, or ESC-related codes.
- Inspect wheel-speed sensor connectors and wiring at each wheel for signs of damage, corrosion, or loose connections.
- Check the steering-angle sensor and yaw-rate sensor for proper mounting, calibration, and operation; misalignment or failure can disable AdvancTrac.
- Test the vehicle’s battery and charging system; low voltage can affect sensors and control modules involved in stability control.
- Consider recent work that may have disturbed module programming or the re-learn process, such as a battery disconnect or aftermarket installation.
Resolving the underlying fault and clearing the codes with a scan tool, followed by an appropriate drive cycle, is typically required for the warning to disappear.
Drive cycle and re-learning tips
After repairs, the AdvancTrac system often re-learns during normal driving. A typical cycle involves steady highway speeds and varied acceleration over 10–20 miles, but results can vary by vehicle and the nature of the fault. If the warning persists after a repair and reset, professional diagnosis is advised.
Power Steering service warning: what to check
The 2011 Fusion uses an electric power-steering system (EPAS). A “Power Steering Service” warning can indicate faults in the EPAS motor or control module, steering-angle sensor data, battery/charging issues, or wiring faults. Since EPAS relies on electrical power and sensors, voltage and data integrity are essential for proper function.
Common checks before replacement include the following areas:
- Inspect the battery condition and charging system; insufficient voltage can cause EPAS trouble codes or reduced assist.
- Inspect EPAS motor, wiring harnesses, and electrical connectors for corrosion, looseness, or damage.
- Check fuses and relays related to the steering system and EPAS control module.
- Review steering-angle sensor data and calibration; a miscalibrated SAS can trigger a steering warning.
- Read EPAS-specific codes with a proper scan tool to pinpoint whether the fault is motor, sensor, or communication related.
Addressing the root cause and clearing EPAS codes with a diagnostic tool, followed by a careful drive cycle, is typically necessary to reset the warning.
Resetting the warnings after repairs
There is no universal, one-step reset for AdvancTrac or EPAS warnings. After performing the necessary repairs, a professional-grade scan tool is usually used to clear the codes. The vehicle should then be driven gently to allow the systems to re-learn. If the warning returns, or if the system behaves abnormally (unassisted steering, erratic stability behavior), seek professional service promptly.
In some cases a battery disconnect or reprogramming may be recommended by a technician as part of a re-learn procedure, but this should only be done by someone with the proper equipment and knowledge to avoid creating new faults.
When to seek professional help
If the Service AdvancTrac or Power Steering warnings persist after basic checks and code clearing, or if you notice any steering stiffness, abnormal noises, or reduced steering response, it is safest to have a Ford technician diagnose the system. Advanced recalibration, module updates, or replacements may be required for a proper and safe resolution.
Summary
Resetting AdvancTrac and Power Steering warnings on a 2011 Fusion isn’t accomplished with a simple button push. The reliable path is diagnosing the underlying fault with a proper scan tool, repairing issues in sensors, wiring, or the battery/charging system, clearing the codes, and then performing a drive cycle to let the systems re-learn. If issues persist, professional diagnosis and service are advised to ensure safe and accurate operation of stability control and steering assist.
