Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, flathead screwdriver, and possibly a steering wheel puller.
Ensure the vehicle is parked on a level surface with the ignition turned off. Disconnect the 12V battery for safety.

2. Remove Steering Wheel

Sub-steps:
1. Remove the airbag module by gently prying off the clips on the back of the steering wheel.
2. Disconnect the airbag connectors and set the airbag aside in a safe location.
3. Use a socket wrench to remove the central nut securing the steering wheel.
4. Mark the position of the steering wheel with tape for alignment.
5. Carefully pull the steering wheel off the column (use a steering wheel puller if necessary).

3. Inspect and Repair Steering Column Components

Sub-steps:
1. Inspect the steering column for any damaged components, including the steering shaft and couplings.
2. Check the electric power steering (EPS) unit for functionality by connecting a multimeter to test voltage and ground.
3. If there are faulty components, replace them with OEM parts:
  - Steering column assembly
  - EPS module
4. Clean any debris or corrosion from connectors and apply dielectric grease.

4. Reassemble Components

Sub-steps:
1. Reinstall the steering wheel, aligning it with the tape marking.
2. Torque the central nut to the manufacturer's specified value (refer to the service manual).
3. Reconnect the airbag module, ensuring connectors are secure.
4. Reattach any panels removed during disassembly.
