Solution

1. Preparation

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

2. Wheel Speed Sensor Inspection

Sub-step 1: Remove the wheel covering the wheel speed sensor.
Sub-step 2: Disconnect the electrical connector of the wheel speed sensor.
Sub-step 3: Measure the resistance of the sensor using a multimeter; it should measure between 1,000 - 2,000 ohms.
Sub-step 4: Clean the sensor and its mounting area to remove any debris.
Sub-step 5: Reconnect the sensor and reinstall the wheel.

3. Brake System Check

Sub-step 1: Inspect the brake fluid reservoir and refill with the appropriate brake fluid if low (DOT 3 or DOT 4 as specified).
Sub-step 2: Visually check the brake lines for leaks or damage.
Sub-step 3: Inspect the ABS module for any signs of corrosion or loose connections.
Sub-step 4: Reconnect the battery terminal and clear any stored codes using the OBD-II scanner.

4. Traction Control Switch Verification

Sub-step 1: Locate the traction control switch on the dashboard.
Sub-step 2: Press the switch to toggle the traction control system on and off.
Sub-step 3: Verify that the light turns off when the system is enabled.
