Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts before starting the repair.

2. Inspect and Top Off Power Steering Fluid

Check the power steering fluid reservoir; if low, top off with the correct fluid.
Inspect the reservoir for cracks or leaks.

3. Replace Power Steering Pump (if faulty)

Tools Required: Socket set, torque wrench, screwdrivers, fluid catch pan.
Disconnect the battery to prevent any electrical shorts.
Remove the drive belt by loosening the tensioner and sliding it off the power steering pump pulley.
Disconnect the power steering fluid lines from the pump; use a fluid catch pan to collect any spilled fluid.
Unbolt the power steering pump from its mounting bracket and remove it.
Install the new power steering pump by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the fluid lines and re-install the drive belt.

4. Clear Error Codes and Test

Tools Required: OBD-II scanner.
Reconnect the battery and start the engine.
Use the OBD-II scanner to clear any fault codes related to EPS.
Monitor the EPS light; if it remains off, perform a test drive to confirm steering operation.
