Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the vehicle's battery to prevent electrical shorts.

2. Inspect and Clean ABS Sensors

Tools Required: Socket set, cleaning brush, brake cleaner.
Remove the wheel that has the ABS sensor to access it.
Clean the ABS sensor and the area around it with brake cleaner and a brush to remove any debris or dirt.
Reinstall the wheel and repeat for all wheels as necessary.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid tester, siphon pump (if necessary).
Remove the brake fluid reservoir cap and check the fluid level and condition.
If fluid is contaminated or low, siphon out the old fluid.
Fill with new brake fluid that meets manufacturer specifications, usually DOT 4 or DOT 5.1.
Replace the reservoir cap securely.

4. Test Steering Angle Sensor

Tools Required: OBD-II scanner, vehicle service manual.
Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use the OBD-II scanner to access the steering angle sensor data.
If the readings are inconsistent or out of range, follow the service manual to recalibrate or replace the sensor.

5. Check Wheel Speed Sensors

Tools Required: Multimeter, socket set.
Inspect the wheel speed sensors for physical damage.
Use a multimeter to test the resistance of each sensor; it should be within the manufacturer's specifications.
If any sensor is faulty, remove and replace as necessary, ensuring proper connection.
