Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace EPS Fuse

Locate the EPS fuse in the fuse box.
Use the fuse puller to remove the EPS fuse and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Repair Electrical Connections

Visually inspect the wiring harness connected to the EPS motor for any visible damage.
If any wires are frayed or disconnected, repair or replace as necessary.
Ensure all connectors are firmly seated and free of corrosion.

4. Replace EPS Motor (if necessary)

If the EPS motor is faulty, follow these steps:
1. Remove the steering column cover to access the EPS motor.
2. Disconnect any electrical connectors from the EPS motor.
3. Unbolt the EPS motor from the steering column (typically requires a socket set).
4. Install the new EPS motor by reversing these steps and ensure all bolts are torqued to manufacturer specifications.

5. Steering Angle Sensor Calibration

After replacing the EPS motor, use a diagnostic tool to reset and calibrate the steering angle sensor.
Follow the tool's instructions to complete the calibration process.
