Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Gather necessary tools and parts.
Disconnect the negative terminal of the battery to avoid electrical shock.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensors and the surrounding area using a soft brush or cloth.
Reconnect any disconnected sensors ensuring secure connections.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
If the fluid level is low, top it up with the manufacturer-recommended brake fluid.
Inspect for any leaks in the brake lines or around the calipers.

4. Test and Calibrate Steering Angle Sensor

Using a scan tool, access the steering angle sensor data.
Follow the on-screen instructions to perform a calibration procedure if necessary.
Ensure the sensor readings align with the steering wheel position.

5. Inspect ABS Module and Wiring

Locate the ABS module, typically near the master cylinder.
Visually inspect the wiring harness for any frays or corrosion.
If the module appears faulty, refer to manufacturer specifications for replacement.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal securely.
Use the OBD-II scanner to clear any error codes.
Start the vehicle and observe the dashboard for any warning lights.
