Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and a torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical work.

2. Inspect Wheel Speed Sensors

Locate each wheel speed sensor on all four wheels.
Remove the sensor connector and visually inspect for corrosion or damage.
Use a multimeter to check the sensor resistance; replace if out of specifications.

3. Check Traction Control Module

Locate the traction control module, typically found under the dashboard or near the ABS unit.
Inspect the electrical connectors and wiring for signs of damage or corrosion.
If no visible issues are found, connect the OBD-II scanner and check for any fault codes related to the module. Replace if necessary.

4. Inspect Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the recommended brake fluid (DOT 4).
Inspect for leaks in the brake lines or connections.

5. Test ABS System

Reconnect the battery and use the OBD-II scanner to perform an ABS system check.
Follow the scanner instructions to run a diagnostic test on the ABS system.
Address any faults that may appear, which could also impact the traction control system.
