Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is turned off before beginning work.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Tire pressure gauge

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner prompts to retrieve any stored error codes and note them for further troubleshooting.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor wiring connector and inspect for corrosion or damage.
Clean the sensor and the area around it to ensure proper function.
Reconnect the wiring and ensure the connection is secure.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the appropriate brake fluid as per the owner's manual.
Inspect for any signs of brake fluid leakage around the reservoir and brake lines.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch for continuity when pressed.
If the switch fails, replace it with a new component.

6. Inspect ABS Module and Wiring

Locate the ABS module, typically found near the brake master cylinder.
Inspect the wiring harness for any signs of wear or damage.
If damaged, repair or replace the wiring as necessary.

7. Verify Tire Condition

Check tire pressure using a tire pressure gauge; ensure all tires are inflated to the recommended PSI.
Inspect tires for uneven wear or inadequate tread depth, replacing them if necessary.
