Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, wheel chocks, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical shorts.

2. Scanning and Identifying Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note any error codes related to the traction control system.

3. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Raise the vehicle using a jack and secure it with jack stands.
Locate each wheel speed sensor and check for any visible damage or disconnections.
Use a multimeter to test the resistance of each sensor; replace any that are outside of specification.

4. Check Brake Fluid and System

Inspect the brake fluid reservoir for proper fluid level.
Look for any signs of leaks in the brake lines or around the master cylinder.
If brake fluid is low, refill to the recommended level and check for leaks.

5. Examine ABS Control Module

Locate the ABS control module, usually found near the brake master cylinder.
Inspect for signs of corrosion or physical damage.
If necessary, test the module’s electrical connections using a multimeter.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is activated.
Replace the switch if it does not function correctly.

7. Reconnect Battery and Clear Codes

Reconnect the battery once all checks and repairs are completed.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and observe if the traction control light remains off.
