Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris surrounding the sensors.
Use a multimeter to test the resistance of each sensor; replace any that are out of specification.
Reconnect any loose wiring or connectors found during the inspection.

3. Check and Repair ABS Control Module

Access the ABS control module, typically located near the master cylinder.
Inspect the wiring harness for signs of damage or corrosion.
If necessary, replace the ABS control module following the manufacturer’s guidelines, ensuring all connections are secure.

4. Test Brake Pedal Position Sensor

Locate the brake pedal position sensor, usually mounted near the brake pedal.
Use a multimeter to check the sensor's output voltage while depressing the brake pedal; ensure it meets specifications.
Replace the sensor if readings are out of range.

5. Calibrate Steering Angle Sensor

Use an OBD-II scanner to access the steering angle sensor calibration menu.
Follow the on-screen instructions to recalibrate the sensor.
Clear any DTCs from the system after calibration.
