Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is turned off. Wear safety goggles for eye protection.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow the scanner instructions to retrieve and clear the brake-related error codes.
Disconnect the scanner after clearing the codes.

3. Inspect ABS Module and Wiring

Locate the ABS module under the hood or near the brake booster.
Visually inspect the module and wiring harness for any signs of damage or loose connections.
If any damage is found, repair or replace the affected components.

4. Check Brake Fluid and System

Open the brake fluid reservoir cap and check fluid levels; top off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect the brake lines for leaks; if leaks are found, replace the affected brake line or component.

5. Test Wheel Speed Sensors

Disconnect the electrical connectors from each wheel speed sensor.
Using a multimeter, check the resistance of each sensor according to the manufacturer’s specifications.
Replace any faulty wheel speed sensors.

6. Reassemble and Test Drive

Reconnect all components and ensure everything is secured.
Test drive the vehicle to ensure that the brake system operates normally and that warning lights are extinguished.
