Solution
1. Preparation
  • Gather tools and parts needed for inspection and repair.
  • Ensure the vehicle is parked on a level surface with the engine turned off.
2. Inspect Power Steering Fluid
  • Remove the power steering fluid reservoir cap.
  • Check the fluid level against the markings on the reservoir.
  • If low, add the recommended power steering fluid type (usually ATF or specific PS fluid) until it reaches the appropriate level.
3. Check Electrical Connections
  • Disconnect the battery to ensure safety while working on electrical components.
  • Inspect the wiring harness connected to the power steering module for frays or loose connections.
  • Clean any corroded terminals with electrical contact cleaner.
4. Test Power Steering Motor
  • Reconnect the battery and turn the ignition to the ON position without starting the engine.
  • Use a multimeter to test the voltage at the power steering motor connector. It should read around 12 volts.
  • If the voltage is absent or fluctuating, the motor may be faulty and require replacement.
5. Clear Fault Codes
  • After repairs are made, use the OBD-II scanner to clear any fault codes in the EPS system.
  • Disconnect the scanner and turn off the ignition.
