Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power steering fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for damage; replace with a fuse of the same amperage if blown.

3. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; add manufacturer-recommended fluid if low.
If the fluid is dark or contaminated, drain and replace with new fluid.

4. Inspect EPS Motor and Wiring

Remove any covers obstructing access to the EPS motor.
Visually inspect the motor and wiring for signs of wear, damage, or disconnection.
Repair or replace any damaged components as needed.

5. Test EPS Control Module

Reconnect the battery terminal.
Use a multimeter to check the EPS control module's voltage and ground connections.
If the readings are outside specifications, replace the control module.
