Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the vehicle's battery to ensure safety.
Remove any obstructions in the workspace around the steering column.

2. Inspect and Replace EPS Fuse/Relay

Locate the fuse box under the dashboard and identify the EPS fuse using the diagram on the cover.
Remove the EPS fuse using a fuse puller or pliers, and inspect it for continuity. Replace if blown (typically a 15A fuse).
Locate the EPS relay, remove it, and check it for continuity with a multimeter. Replace if faulty.

3. Repair Wiring and Connectors

Carefully examine the wiring harness connected to the EPS motor for frayed or damaged wires.
Clean any corrosion from connectors using electrical contact cleaner.
Repair or replace damaged wiring and connectors as necessary, ensuring all connections are secure.

4. EPS Motor Replacement (if required)

If the EPS motor is found to be defective, remove it by:
- Disconnecting the electrical connectors.
- Removing the mounting bolts (typically 3-4) using a socket set.
- Carefully pulling the motor out from the steering column.
Install the new EPS motor by reversing the removal steps, ensuring all bolts are torqued to the manufacturer's specifications (usually around 20 Nm).

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn the ignition to the ON position without starting the engine to allow the EPS system to initialize.
Start the vehicle and check for proper steering function and absence of warning lights.
