Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down if it has been driven recently.

2. Inspect and Replace EPS Fuse

Locate the fuse box in the cabin or engine compartment.
Remove the cover and identify the EPS fuse using the diagram on the fuse box.
Use a fuse puller to remove the fuse and inspect it for continuity.
Replace with a new fuse of the same amperage if blown.

3. Inspect Wiring and Connectors

Remove the steering column covers using a socket set.
Visually inspect all wiring and connectors leading to the EPS motor for signs of wear, corrosion, or loose connections.
Use electrical contact cleaner to clean any corroded connectors and ensure they are securely connected.

4. Test EPS Motor

Reconnect the negative battery terminal.
Use a multimeter to check voltage at the EPS motor connector while turning the ignition to the ON position.
If the voltage is absent or below specifications, trace the wiring back to the EPS control module for faults.

5. Replace Steering Angle Sensor (if necessary)

Disconnect the battery and remove the steering wheel using a steering wheel puller.
Unplug the steering angle sensor from its harness.
Remove the sensor from the steering column by unscrewing it.
Install the new steering angle sensor and reconnect the harness.
Reinstall the steering wheel and reconnect the battery.
