Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical shock.

2. Inspect and Replace Fuses and Relays

Locate the fuse box and identify the EPS fuse.
Remove the fuse using a fuse puller and inspect for continuity.
If blown, replace it with the same amperage rating.
Check the EPS relay; if faulty, replace it with a new relay.

3. Check and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, top up with the correct type of power steering fluid (check the owner’s manual).
If the fluid is dark or contaminated, drain the system and flush with new fluid, then refill.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the EPS motor for fraying, corrosion, or disconnection.
Clean any corroded connectors using electrical contact cleaner.
Repair or replace damaged wires as necessary.

5. Test and Replace EPS Motor

Reconnect the battery and use a multimeter to test the EPS motor’s voltage and ground.
If the EPS motor does not function correctly, remove it according to the service manual:
- Disconnect any electrical connectors.
- Remove the bolts securing the motor to the steering column or gear.
- Install a new EPS motor by reversing the removal procedure and ensuring proper torque on bolts.

6. Calibration

After replacing the EPS motor, perform a steering angle sensor reset and recalibration using a scan tool to ensure the system operates correctly.
