Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel assembly.
Remove any dirt or debris from the sensor area using a clean cloth.
Check the wiring and connectors for any signs of wear or damage.
Reattach any loose connections and ensure they are secure.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely after refilling.

4. Align Steering Angle Sensor

Use an OBD-II scanner to reset the steering angle sensor.
If necessary, use a calibration tool to align the sensor according to the manufacturer specifications.
Follow the instructions for your specific model to ensure proper calibration.

5. Inspect ABS Module

Locate the ABS module, typically found near the brake master cylinder.
Check for any visible damage or corrosion on the module and its connectors.
If issues are detected, replace the ABS module according to the manufacturer’s guidelines.
