Understanding the EPS Light

The Electronic Power Steering (EPS) light on your Hyundai Elantra indicates a problem with the power steering system. When this light illuminates, it often means the power assist feature is not functioning correctly, making steering more difficult.

Common Causes of EPS Light

  • Software glitches
  • Faulty steering angle sensor
  • Worn steering column components
  • Low battery voltage
  • Damaged wiring or connections
  • Failed power steering control module

Troubleshooting Steps

1. Reset the System

  • Turn off the engine and wait for 10 minutes
  • Restart the car and drive for a short distance
  • Check if the EPS light turns off

2. Check the Battery

  • Ensure battery terminals are clean and tight
  • Test battery voltage (should be around 12.6V when off, 13.7-14.7V when running)
  • Replace the battery if it's weak or old

3. Inspect Electrical Connections

  • Look for loose or corroded wires in the steering column area
  • Clean any corrosion and secure connections

4. Check Fuses

  • Locate the EPS fuse in the fuse box (refer to your owner's manual)
  • Replace if blown

5. Perform a Diagnostic Scan

  • Use an OBD-II scanner to check for error codes
  • Common codes: C1260, C1259, C1261 (steering angle sensor issues)

6. Calibrate the Steering Angle Sensor

  • Some Elantra models require recalibration after battery disconnection or steering work
  • Use a professional-grade scan tool to perform an Absolute Steering Position (ASP) calibration

Professional Repair Options

If DIY troubleshooting doesn't resolve the issue:

1. Software Update: A dealership can perform the latest EPS software update

2. Steering Column Replacement: In some cases, the entire steering column may need replacement

3. Control Module Replacement: The EPS control module might be faulty and require replacement

Preventive Measures

  • Regular battery maintenance
  • Avoid sudden impacts to the steering system
  • Address any steering abnormalities promptly

When to Seek Professional Help

Seek a professional mechanic if:

  • The EPS light persists after basic troubleshooting
  • You experience significant steering difficulty
  • There are unusual noises from the steering column

Remember, driving with a malfunctioning EPS system can be dangerous. If the steering becomes too difficult to control, it's best to have the vehicle towed to a repair shop.
