2
Check for any Diagnostic Trouble Codes (DTCs) using an OBD-II scanner.
3

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level against the markings.
If low, top off with the recommended power steering fluid (Toyota ATF Type T-IV).
Replace the cap securely.

3. Inspect EPS Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse related to the power steering system (refer to the owner's manual for specific fuse location).
Remove the fuse and inspect it visually for any signs of damage.
If blown, replace it with a fuse of the same amperage.

4. Verify Electrical Connections

Reconnect the negative battery terminal.
Check the wiring harness connected to the EPS motor for any loose connections or damage.
Ensure the steering angle sensor is properly connected.
If any connections are loose or corroded, clean and secure them.

5. Reset EPS Light

Turn the ignition key to the "ON" position without starting the engine.
Wait for the EPS light to turn off automatically (if the issue is resolved).
If the light remains on, start the engine and allow it to idle for a few minutes to see if it resets.
If necessary, use an OBD-II scanner to clear any stored DTCs, which may include steering-related codes.
