Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
Ensure the vehicle is on a flat surface and the engine is off. Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir and check the fluid level.
If the fluid is low, top it off with the manufacturer-recommended power steering fluid.
If the fluid is dirty or contaminated, drain the old fluid and replace it with fresh fluid.

3. Repair or Replace Power Steering Control Module

Tools Required: Torx screwdriver set, socket set.
Locate the power steering control module, usually mounted near the steering column.
Disconnect the electrical connectors and remove the mounting bolts to take out the module.
Install the new module by reversing the removal steps and ensuring all connections are secure.
Torque the bolts to the manufacturer's specifications.

4. Reconnect Battery and Clear Fault Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored EPS fault codes.
Start the vehicle and let it idle for a few minutes to allow the system to recalibrate.

5. Test Drive

Take the vehicle for a test drive to ensure the EPS light remains off and the steering system operates smoothly.
