Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery (negative terminal) to ensure safety during inspection.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Inspect the fluid level; if low, refill with the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Reconnect the battery and check if the warning light has cleared.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure with jack stands.
Remove the wheel to access the wheel speed sensors.
Clean the sensors and their connectors if dirty; ensure they are securely connected.
Reattach the wheels and lower the vehicle.

4. Test the ABS Module

Use the OBD-II scanner to access ABS module data.
Check for any fault codes related to the ABS system.
If codes are present, follow troubleshooting steps specific to those codes.

5. Steering Angle Sensor Calibration

Start the vehicle and turn the steering wheel from lock to lock to reset the steering angle sensor.
Use the diagnostic scanner to confirm that the steering angle sensor values are within the specified range.
