Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Retrieve and Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the ON position without starting the engine.
Retrieve any error codes related to the traction control system.
Document the codes for further analysis.

3. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Disconnect the electrical connectors and inspect the sensors for dirt or damage.
Use a multimeter to check sensor resistance (should be within OEM specs).
Clean or replace any faulty sensors as necessary.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level and top off with the recommended brake fluid if low.
If the fluid is contaminated, perform a brake fluid flush.

5. Test Traction Control Switch

Locate the traction control switch on the center console.
Use a multimeter to check for continuity when the switch is engaged.
Replace the switch if it fails the continuity test.

6. Reassemble and Clear Codes

Reconnect all components and ensure all connections are secure.
Clear any stored error codes from the OBD-II scanner.
