Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and turn off the ignition.
Disconnect the battery to avoid electrical shorts during repairs.

2. Inspect and Repair Steering Angle Sensor

Locate the steering angle sensor, which is typically mounted on the steering column.
Sub-steps:
1. Remove the steering column cover using a socket set.
2. Disconnect the electrical connector from the steering angle sensor.
3. Visually inspect the sensor for damage.
4. If damaged, replace the steering angle sensor with a new one.
5. Reconnect the electrical connector and replace the steering column cover.

3. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Sub-steps:
1. Remove the cap and check the fluid level against the minimum and maximum markings.
2. If low, top off with the recommended power steering fluid type.
3. Inspect for leaks around the hoses and connections; repair or replace as necessary.

4. Clear Error Codes

Reconnect the battery.
Use the OBD-II scanner to clear any fault codes that were recorded during the diagnostic process.
Test drive the vehicle to confirm that the beeping sound has stopped.
