Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Inspect and Replace EPS Fuse

Locate the EPS fuse in the fuse box (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown.
Reinstall the new fuse and reconnect the battery.

3. Check and Clean EPS Motor Connector

Locate the EPS motor connector on the steering column.
Disconnect the connector and inspect for corrosion or damage.
Clean the connector pins with electrical contact cleaner.
Reconnect the connector securely.

4. Measure EPS Motor Voltage

Reconnect the battery.
Use a multimeter to measure voltage at the EPS motor connector while the ignition is on (do not start the engine).
Voltage should be within manufacturer specifications (typically around 12V).
If voltage is inadequate, check wiring for damage or shorts.

5. Inspect Steering Column and Rack

Visually inspect the steering column for any signs of wear or damage.
Check the steering rack for leaks or physical damage.
If any components are damaged, replace them as necessary according to manufacturer specifications.

6. Test Drive

Once repairs are completed, take the vehicle for a test drive to assess steering performance.
Monitor for any abnormal noises or steering difficulty.
