Solution

1. Preparation

Tools Needed: OBD-II scanner, multimeter, socket set, torque wrench, steering wheel puller (if necessary)
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace EPS Fuse

Locate the fuse box (usually under the dashboard or hood).
Remove the EPS fuse and inspect it for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage.

3. Check and Refill Power Steering Fluid

If applicable, locate the EPS fluid reservoir and check the fluid level.
If low, add the manufacturer-recommended EPS fluid until it reaches the appropriate level.
Inspect for leaks around hoses and connections; replace any damaged components.

4. Repair or Replace EPS Motor

Remove any covers or components obstructing access to the EPS motor.
Disconnect the wiring harness connected to the EPS motor.
Unbolt the motor from its mounting points and carefully remove it.
Install the new EPS motor by reversing the removal steps, ensuring all connections are secure.
Torque bolts to the manufacturer's specifications.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for the EPS warning light on the dashboard.
Test the steering operation at various speeds to verify responsiveness and assist.
