Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect Brake System Components

Brake Fluid Level: Check the brake fluid reservoir for proper fluid level. If low, fill with the recommended brake fluid (DOT 3 or DOT 4).
Brake Lines: Visually inspect brake lines and hoses for leaks or damage.
Brake Pads and Rotors: Remove the wheel and inspect brake pads for wear and rotors for scoring or warping.

3. Replace Faulty Components (if needed)

Brake Sensor: If the diagnostic codes indicate a faulty brake sensor, locate it on the brake system, remove the electrical connector, and unscrew it. Install the new sensor and reconnect the wiring.
ABS Module: If the ABS module is faulty, disconnect the battery, remove the module by unscrewing it from its mount, and install the new module in reverse order.

4. Reassemble and Test

Reinstall any components removed during inspection or repair.
Reconnect the battery if it was disconnected.
Start the vehicle and check for the illumination of the brake and ABS warning lights.
