Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.
Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, torque wrench.

2. Address Diagnostic Trouble Codes

Sub-step 1: Clear the codes using the OBD-II scanner after taking note of them.
Sub-step 2: If the codes reappear, proceed to inspect the corresponding components identified by the codes.

3. Brake Fluid Inspection and Replacement

Sub-step 1: Open the hood and locate the brake fluid reservoir.
Sub-step 2: Check the fluid level; if low, top it off with the recommended brake fluid (DOT 3 or DOT 4).
Sub-step 3: If the fluid is contaminated (dark or murky), perform a brake fluid flush:
- Attach a hose to the caliper bleeder screw and place the other end in a container.
- Open the bleeder screw and pump the brake pedal until clean fluid flows out.
- Close the bleeder screw and repeat for all wheels.

4. Brake Pad and Rotor Replacement

Sub-step 1: Remove the wheel using a jack and jack stands for safety.
Sub-step 2: Remove caliper bolts and slide the caliper off the rotor.
Sub-step 3: Replace worn brake pads and inspect rotors for warping or scoring; replace if necessary.
Sub-step 4: Reinstall the caliper, ensuring all bolts are torqued to manufacturer's specifications (usually around 25 ft-lbs).

5. ABS Component Repair

Sub-step 1: Inspect and clean the ABS wheel speed sensors; replace if damaged.
Sub-step 2: Check the wiring harness for continuity using a multimeter; repair or replace any damaged wires.
Sub-step 3: Test the ABS module for faults; replace if necessary.
