Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool down if it has been running.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Remove the wheel and tire assembly.
Locate the wheel speed sensors at each wheel hub.
Check for physical damage, corrosion, or loose connections.
Use a multimeter to test the sensor output; replace if faulty.

3. Check Brake Fluid

Locate the master cylinder reservoir.
Inspect the brake fluid level; top off with the manufacturer-recommended fluid type if low.
Check for leaks in the brake system that may affect fluid levels.

4. Examine the ABS Module

Tools Required: OBD-II scanner.
Connect the scanner to retrieve any ABS-related fault codes.
Follow the manufacturer's service manual for specific troubleshooting of the ABS module.
Clear any fault codes and retest the system.

5. Inspect Steering Angle Sensor

Locate the sensor, typically mounted on the steering column.
Ensure the sensor is properly aligned and has good electrical connections.
If necessary, recalibrate the steering angle sensor using a diagnostic tool.
