Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and torque wrench.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the wiring harness from the sensors.
Check the wiring for frays or breaks; repair or replace as necessary.
Clean contamination on the sensor and mounting area.
Reconnect the sensors and ensure they are securely mounted.

3. Check ABS Module

Locate the ABS module, usually found near the brake master cylinder.
Inspect connectors for corrosion or loose connections.
Use a multimeter to check for proper voltage and ground at the ABS module.
If faulty, replace the ABS module with a compatible part.

4. Verify Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Check the fluid level against the minimum and maximum markings.
If low, top off with manufacturer-recommended brake fluid.
Inspect for any leaks in the brake system.

5. Test Traction Control Switch

Locate the traction control switch, typically on the dashboard or center console.
Use a multimeter to check for continuity when the switch is engaged.
Replace the switch if it does not function properly.
