Solution

1. Preparation

Gather all necessary tools and parts before starting repairs.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top it off with the recommended power steering fluid (consult owner’s manual for specifications).
Inspect for any leaks after refilling.

3. Replace Power Steering Pump (if necessary)

Tools Required: Socket set, wrench set, fluid extraction tool, torque wrench.
Remove the drive belt from the power steering pump.
Disconnect the power steering lines using a wrench, and be prepared to catch any dripping fluid.
Remove the mounting bolts and take out the old pump.
Install the new power steering pump by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications (consult service manual for torque values).
Reconnect the power steering lines and reinstall the drive belt.

4. Reconnect Battery and Clear Codes

Reconnect the battery and ensure all connections are secure.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and check if the EPS light remains off.
