Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Inspect and Repair Wiring

Sub-steps:
1. Visually inspect the wiring harness connected to the electric power steering module for any frays, cuts, or corrosion.
2. Clean any corrosion from connectors using an electrical contact cleaner.
3. Repair or replace damaged wires using electrical tape or heat-shrink tubing.

3. Replace Power Steering Motor (if faulty)

Sub-steps:
1. Remove the steering column covers to access the electric power steering motor.
2. Disconnect the electrical connector from the power steering motor.
3. Unbolt the motor from its mounting points using the appropriate socket (usually 10mm).
4. Install the new power steering motor by reversing the removal steps and ensuring all bolts are tightened to the manufacturer's specifications.

4. Refill and Bleed Power Steering Fluid (if applicable)

Sub-steps:
1. If the system is hydraulic, refill the power steering fluid reservoir with the specified fluid type (check owner's manual).
2. Bleed the steering system by turning the steering wheel from lock to lock several times with the engine running, ensuring there are no air bubbles in the reservoir.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the EPS warning light is still illuminated.
Test the steering function to ensure it operates smoothly.
