Solution

1. Preparation

Gather tools and ensure a safe working environment.
Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, jack and jack stands, brake cleaner, safety goggles.
Safety Warnings: Always wear safety goggles and gloves. Ensure the vehicle is on a level surface and secured with jack stands.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve brake-related error codes and note their descriptions for further investigation.

3. Inspect Brake Components

Remove the wheel to access the brake assembly.
Check the brake pads for wear; replace if thickness is below 3mm.
Inspect the brake rotors for scoring or warping; replace if necessary.
Ensure that brake lines and hoses are free from leaks and damage.

4. Address Brake Fluid Issues

If the brake fluid is low, top it off with the manufacturer's specified brake fluid.
If the fluid is contaminated (dark or murky), perform a brake fluid flush.
Bleed the brakes to remove air from the brake lines after fluid replacement.

5. Repair or Replace Sensors

If error codes indicate a faulty ABS sensor, locate the sensor in the wheel hub assembly.
Disconnect the sensor’s electrical connector.
Remove the sensor using a socket, then install the new sensor and reconnect the wiring.
Ensure the sensor is properly secured.

6. Clear Codes and Test

After completing repairs, use the OBD-II scanner to clear any error codes.
Start the vehicle and check the dashboard for warning lights.
Conduct a test drive to ensure the brakes function properly and no codes reappear.
