Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace EPS Fuse

Locate the fuse box, usually found under the dashboard or near the engine compartment.
Remove the EPS 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 Connector

Locate the EPS motor connector, typically near the steering column.
Disconnect the connector and inspect for corrosion or damage.
Clean the connector pins using electrical contact cleaner.
Reconnect the connector securely.

4. Test EPS Motor Voltage

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Using a multimeter, measure the voltage at the EPS motor connector while turning the steering wheel.
If voltage is not within the manufacturer's specifications, further investigation into wiring or motor issues is required.

5. Inspect and Replace EPS Motor (if necessary)

If the EPS motor is faulty, remove it by detaching the mounting bolts.
Disconnect the electrical connector from the motor.
Install the new EPS motor by reversing the removal process.
Ensure all connections are secure and properly torqued according to manufacturer specifications.
