Solution

1. Preparation

Gather necessary tools and parts for the repair.
Disconnect the vehicle battery to prevent electrical shorts.
Allow the vehicle to cool if it has recently been in operation.

2. Inspect Wheel Speed Sensors

Remove the wheel covers or lug nut covers (if applicable).
Lift the vehicle using a jack and secure it with jack stands.
Inspect each wheel speed sensor for dirt, damage, or corrosion.
Clean the sensors with an appropriate electrical cleaner if dirty.
Reconnect any loose connections.

3. Check Traction Control Module

Locate the traction control module, usually found near the ABS module.
Visually inspect the module and wiring harness for signs of damage or corrosion.
Use a multimeter to test the connections for continuity and proper voltage.
Replace the module if any faults are detected.

4. Inspect Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; top off with manufacturer-recommended fluid if low.
Inspect brake lines for leaks that may indicate fluid loss.

5. Test the ABS System

Reconnect the vehicle battery.
Start the vehicle and perform a brake test at low speeds to check ABS operation.
Monitor the dashboard for any warning lights; if the ABS light remains illuminated, further diagnostics may be required.
