Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
- Sub-step 1: Remove the wheel covering the suspected wheel speed sensor.
- Sub-step 2: Disconnect the electrical connector from the wheel speed sensor.
- Sub-step 3: Use a multimeter to test the sensor's resistance according to manufacturer specifications.
- Sub-step 4: If faulty, replace with a new wheel speed sensor.

3. Check Brake Fluid Level

Tools Required: Funnel, brake fluid (DOT 3 or DOT 4)
- Sub-step 1: Locate the brake fluid reservoir under the hood.
- Sub-step 2: Check the fluid level against the "min" and "max" indicators.
- Sub-step 3: If low, add the appropriate brake fluid until it reaches the proper level.

4. Inspect ABS Module

Tools Required: Basic hand tools
- Sub-step 1: Locate the ABS module, usually near the master cylinder.
- Sub-step 2: Examine for physical damage or corrosion on connectors.
- Sub-step 3: Clean any corroded connectors or replace the module if damaged.

5. Test Traction Control Switch

Tools Required: Multimeter
- Sub-step 1: Locate the traction control switch (typically on the dashboard).
- Sub-step 2: Disconnect the switch from its connector.
- Sub-step 3: Use a multimeter to check for continuity when the switch is pressed.
- Sub-step 4: Replace switch if it is faulty.

6. Reconnect Battery and Clear Codes

Tools Required: None
- Sub-step 1: Reconnect the negative battery terminal.
- Sub-step 2: Use the OBD-II scanner to clear any error codes.
- Sub-step 3: Start the vehicle and check if the traction control light is still illuminated.
