Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid electrical shock.

2. Check and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the correct type of fluid as specified in the owner's manual if low.
If the fluid appears dirty or contaminated, drain and replace it with new fluid.

3. Inspect and Repair Wiring

Examine the wiring harness connected to the EPS motor for fraying or breaks.
Repair any damaged wires using heat-shrink tubing and solder.
Ensure all connectors are secure and free of corrosion.

4. Replace Power Steering Control Module (if necessary)

If diagnostic codes indicate a faulty control module, remove the old module.
- Unscrew the module mounting bolts.
- Disconnect wiring harness from the module.
Install the new control module by connecting the wiring harness and securing it with bolts.
Torque bolts to manufacturer specifications.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and check if the EPS warning light is still illuminated.
