Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers), torque wrench.
Safety Warnings: Disconnect the negative battery terminal before starting any electrical work.

2. Replace EPS Fuse (if necessary)

Locate the fuse box under the dashboard or in the engine compartment.
Identify the EPS fuse using the diagram on the fuse box cover.
Remove the faulty fuse and replace it with a new fuse of the same amperage.
Reconnect the negative battery terminal.

3. Repair or Replace Wiring and Connectors

If damaged wiring or connectors are found during inspection, repair them by soldering or replacing as necessary.
Ensure all connections are secure and free of corrosion.
Use heat-shrink tubing to insulate any repairs.

4. Replace EPS Motor (if diagnosed as faulty)

Disconnect the battery again for safety.
Remove any panels or obstructions to access the EPS motor.
Unplug the electrical connector from the EPS motor.
Remove the mounting bolts using a socket set to detach the EPS motor from the steering column.
Install the new EPS motor in reverse order, ensuring all connections are secure and properly torqued.

5. Calibration

After repairs, reconnect the battery.
Use the OBD-II scanner to perform a steering angle sensor calibration if applicable.
Follow the on-screen instructions to complete the calibration process.
