Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor connector by pressing the release tab.
Clean the sensor area and check for physical damage.
If damaged, replace the wheel speed sensor with a new one.
Reconnect the sensor and ensure it is securely fastened.

3. Check ABS Module

Locate the ABS module, usually found near the brake master cylinder.
Inspect for any visible damage or loose connections.
If error codes indicate a fault, replace the ABS module following the manufacturer’s guidelines.
Bleed the brake system after replacing the ABS module to remove any air trapped in the system.

4. Inspect Wiring and Connectors

Follow the wiring harness from the wheel speed sensors to the ABS module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring and ensure connectors are clean and secure.

5. Verify Brake System Function

Check brake fluid levels and condition; replace if fluid is contaminated.
Inspect brake pads and rotors for wear; replace if necessary.
Test the brake system by applying brakes and ensuring they engage smoothly without unusual sounds.

6. Reconnect Battery

Reconnect the negative battery terminal securely.
Ensure all tools are removed from the engine compartment before starting the vehicle.
