Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrench set, and safety glasses.
Ensure the vehicle is parked on a level surface and the ignition is off before beginning work.

2. Check Power Steering Fluid

Locate the power steering reservoir under the hood.
Remove the cap and check the fluid level against the dipstick.
If low, top up with the manufacturer-specified power steering fluid and check for leaks.

3. Fuse Inspection

Locate the power steering fuse in the fuse box (refer to the owner's manual for location).
Remove the fuse and inspect for continuity using a multimeter.
Replace the fuse if it is blown with the same amperage rated fuse.

4. Electrical Connections

Disconnect the battery before working on electrical components.
Inspect the wiring harness connected to the power steering motor for any signs of wear or corrosion.
Clean any corroded terminals and ensure all connections are tight.

5. Testing the Power Steering Motor

Reconnect the battery after inspecting the connections.
Use the multimeter to measure voltage at the power steering motor while turning the ignition to the "on" position (do not start the engine).
Voltage should be within the manufacturer's specifications; consult the service manual for exact values.

6. Replace Power Steering Motor (if necessary)

If the motor is defective, disconnect the power steering motor wiring.
Remove the mounting bolts securing the motor to the steering assembly.
Install the new power steering motor and torque the bolts to the manufacturer's specifications.
Reconnect the wiring harness and test for proper operation.
