Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, multimeter, socket set, brake fluid, and safety glasses.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set
Remove the wheel covering the suspected wheel speed sensor.
Disconnect the sensor's electrical connector.
Clean the sensor and the mounting area of any debris.
Reconnect and torque the sensor to manufacturer specifications (typically around 8 Nm).
Repeat for all wheel speed sensors if necessary.

3. Check Brake Fluid Level

Tools Required: None
Locate the brake fluid reservoir under the hood.
Inspect the fluid level; it should be between the minimum and maximum marks.
If low, add the appropriate brake fluid (DOT 4 or as specified in the owner’s manual).
Reconnect the negative battery terminal.

4. Inspect ABS Module

Tools Required: Socket set
Locate the ABS module, typically found near the master cylinder.
Check for any loose connections or corrosion on the wiring harness.
If necessary, tighten connections or clean corrosion with electrical contact cleaner.
Reconnect the negative battery terminal.

5. Test Steering Angle Sensor

Tools Required: Multimeter
Using the multimeter, test the steering angle sensor output while turning the steering wheel.
Ensure the readings change smoothly without erratic fluctuations.
If the output is faulty, replace the steering angle sensor according to manufacturer guidelines.
