EPS Light

The Electric Power Steering (EPS) light in Hyundai vehicles is a warning indicator that illuminates when there's an issue with the power steering system. When this light comes on, drivers may experience difficulty steering, especially at low speeds or when the vehicle is stationary.

Common Causes

Several factors can trigger the EPS light in Hyundai vehicles:

  • Faulty steering angle sensor: This sensor helps determine the position of the steering wheel and can cause issues if malfunctioning.
  • Wiring problems: Loose connections or damaged wiring in the EPS system can trigger the warning light.
  • Control unit failure: The EPS control unit, located in the steering column, may malfunction and need replacement.
  • Power supply issues: Low voltage from the battery or alternator can affect the EPS system's performance.
  • Calibration errors: Improper calibration of the steering angle sensor can cause the EPS light to illuminate.

Troubleshooting Steps

If your Hyundai's EPS light comes on, follow these steps:

1. Check the battery: Ensure the battery is fully charged and functioning correctly.

2. Inspect fuses: Examine the fuses related to the EPS system and replace any that are blown.

3. Scan for error codes: Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to the EPS system.

4. Recalibrate the steering angle sensor: This can often be done using a specialized diagnostic tool.

5. Inspect wiring: Look for any visible damage or loose connections in the EPS wiring harness.

Professional Diagnosis

If the above steps don't resolve the issue, it's best to seek professional help. A certified Hyundai technician can:

  • Perform a comprehensive diagnostic scan
  • Check the EPS control unit for faults
  • Inspect and test the steering angle sensor
  • Verify the proper functioning of the EPS motor

Potential Repairs

Depending on the diagnosis, repairs may include:

  • Replacing the EPS control unit
  • Repairing or replacing wiring
  • Replacing the steering angle sensor
  • Updating the EPS system software

It's important to address EPS issues promptly to ensure safe vehicle operation and prevent further damage to the steering system.

Prevention

To minimize the risk of EPS problems:

  • Regular maintenance: Follow Hyundai's recommended service schedule.
  • Avoid impacts: Protect the steering system from physical damage.
  • Address issues promptly: Don't ignore warning lights or unusual steering behavior.

FAQs About Hyundai EPS Light

    • Is it safe to drive with the EPS light on?
      While the car may still be drivable, it's not recommended as steering could become difficult, especially at low speeds.
    • How much does it cost to fix EPS issues?
      Costs can vary widely, from a simple recalibration (around $100) to replacing the entire steering column (potentially $1000+).
    • Can I reset the EPS light myself?
      While disconnecting the battery might temporarily reset the light, it's best to address the underlying issue to prevent recurrence.
