Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.

2. Check Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Remove the wheel associated with the fault code (as indicated by the OBD-II scanner).
Locate the wheel speed sensor and disconnect the electrical connector.
Inspect the sensor for physical damage or dirt; clean it with a soft cloth if needed.
Use a multimeter to test the sensor resistance (should be typically around 1kΩ to 2kΩ). Replace if outside of specs.
Reinstall the wheel speed sensor and wheel, tightening the bolts to manufacturer specifications (usually around 25-30 Nm).

3. Inspect ABS Control Module

Tools Required: Screwdriver set, multimeter
Locate the ABS control module (usually near the brake master cylinder).
Check for any loose connections or corrosion on the module's connectors.
If necessary, remove the module and inspect the internal circuit board for damage.
If the module is faulty, replace it with a new or refurbished part.

4. Brake Fluid Check

Tools Required: Brake fluid tester or clear container
Open the brake fluid reservoir cap and check the fluid level; add OEM brake fluid if low.
Inspect the fluid for discoloration or particles; if contaminated, perform a brake fluid flush.

5. Final Assembly

Reconnect all electrical connectors and ensure no tools are left in the engine compartment.
Reconnect the negative battery terminal.
Ensure all components are securely reinstalled.
