Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve any stored error codes and document them for analysis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Visually inspect for any physical damage or disconnections.
Clean the sensors if dirt or debris is present using a soft cloth.

4. Check Brake System

Inspect the brake fluid reservoir and ensure it is at the correct level.
Check the condition of brake pads and rotors for wear.
If necessary, replace worn components using a socket set.

5. Recalibrate Steering Angle Sensor

Use the diagnostic tool to navigate to the steering angle sensor calibration setting.
Follow the on-screen instructions to recalibrate.
Ensure the steering wheel is centered during the calibration process.

6. Verify ABS Functionality

Perform a system check for the ABS.
If any faults are detected, replace the ABS control module as needed.
