Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace EPS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the EPS fuse and check for any signs of damage or continuity using a multimeter.
If damaged, replace it with a fuse of the same amperage.

3. Check and Replace Wiring/Connectors

Visually inspect wiring leading to the EPS motor for any frays or disconnections.
Disconnect the wiring harness from the EPS motor.
Clean any corrosion from the connectors using an electrical contact cleaner.
Reconnect the wiring harness securely.

4. Test and Replace EPS Motor (if necessary)

If the EPS motor is not functioning, follow these steps:
