Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to ensure safety during electrical inspections.

2. Check Power Steering Fluid

Tools Required: Container for fluid, funnel, dipstick.
Remove the power steering fluid reservoir cap and check the fluid level using the dipstick.
If low, add the appropriate type of power steering fluid as specified in the owner’s manual.
Inspect for leaks in hoses and connections; repair or replace as needed.

3. Inspect Steering Components

Tools Required: Wrench set, socket set, flashlight.
Visually inspect the steering linkage, tie rods, and ball joints for any signs of wear or damage.
Tighten any loose connections and replace worn components.

4. Test Electronic Power Steering (EPS)

Tools Required: Multimeter, diagnostic scanner.
Reconnect the battery and power the vehicle on.
Use the diagnostic scanner to check for any EPS-related trouble codes.
If codes are present, follow the manufacturer's instructions for troubleshooting those specific codes.
Check wiring and connections for the EPS motor; repair any damaged wires.
