Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Screwdrivers (flathead and Phillips)
Multimeter

2. Fluid Check and Replacement

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check fluid level; if low, add the recommended fluid type (consult owner's manual).
3. If the fluid is dark or contaminated, drain and replace with new fluid.

3. Inspect Steering Column Components

Sub-steps:
1. Remove any interior panels covering the steering column.
2. Inspect the steering shaft for any visible wear or damage.
3. Check the connection points for looseness or corrosion.
4. If any component is damaged, replace as necessary.

4. Testing the EPS System

Sub-steps:
1. Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
2. Use a multimeter to check voltage at the EPS motor connector; it should be within specification (consult service manual).
3. If voltage is absent or low, trace wiring for breaks or shorts.

5. Steering Rack and Tie Rod Inspection

Sub-steps:
1. Raise the front of the vehicle using jack stands.
2. Check for play in the steering rack by manually moving the tie rods.
3. If excessive play is noted, replace the steering rack and/or tie rods as necessary.
