Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, brake fluid, socket set, jack and jack stands, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems; allow the vehicle to cool before performing any work.

2. Retrieve and Address Error Codes

Use the OBD-II scanner to identify and note down the specific brake-related error codes.
Clear the codes after noting them down and perform a test drive to see if they return.

3. Inspect and Replace Components

Brake Fluid Level

Check the brake fluid reservoir; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified).

Brake Pads and Rotors

Jack up the vehicle and remove the wheels.
Inspect brake pads for wear (less than 3mm thickness means replacement).
Measure rotor thickness; if below manufacturer specifications, replace.

Wheel Speed Sensors

Locate each wheel speed sensor.
Disconnect the sensor connector and use the multimeter to test for resistance (check manufacturer specs).
Replace any faulty sensors.

4. Check and Replace Brake Light Switch

Locate the brake light switch and disconnect the wiring harness.
Use a multimeter to test for continuity when the brake pedal is pressed.
Replace the switch if it shows no continuity.
