Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely raised using jack stands if needed.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
- Locate each wheel speed sensor at all four wheels.
- Remove the sensor from its mounting bracket using a socket set.
- Clean the sensor tip with brake cleaner to remove debris and dirt.
- Reinstall the sensor securely and reconnect the electrical connector.

3. Check and Replenish Brake Fluid

Sub-steps:
- Open the master cylinder reservoir cap.
- Inspect the brake fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4).
- Replace the cap securely and check for any signs of leaks.

4. Inspect the ABS Module

Sub-steps:
- Locate the ABS module, typically found near the brake master cylinder.
- Check for any loose or corroded wiring connections.
- If damaged, consider replacing the ABS module.

5. Steering Angle Sensor Calibration

Sub-steps:
- Connect an OBD-II scanner to the vehicle.
- Navigate to the stability control system and check the steering angle sensor calibration.
- If the sensor is out of alignment, follow the scanner's instructions to calibrate it.
