Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Brake Fluid Check and Replacement

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).
If the fluid is dark or contaminated, perform a complete brake fluid flush:
- Attach a brake bleeder kit to the bleeder valve on each brake caliper.
- Open the bleeder valve and allow old fluid to drain while adding new fluid until it runs clear.
- Close the bleeder valve and repeat for all wheels.

3. Brake Component Inspection

Remove the wheel for access to the brake assembly.
Inspect the brake pads for wear; replace if the thickness is below 3mm.
Check the brake rotors for grooves or warping; replace if necessary.
Reassemble the wheel and torque to manufacturer specifications.

4. Brake Switch and ABS Module Inspection

Locate the brake switch and inspect for proper operation. Remove it and test with a multimeter for continuity when the pedal is pressed.
If faulty, replace the brake switch.
Inspect the ABS module connections and wiring harness for any signs of wear or corrosion. Repair or replace as necessary.

5. Reconnect Battery and Reset System

Reconnect the battery.
Use the OBD-II scanner to clear any stored error codes and reset the system.
Test drive the vehicle to ensure proper braking function and verify that no warning lights reappear.
