Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Instructions:
1. Locate the wheel speed sensors at each wheel hub.
2. Visually inspect the sensors and wiring for damage or disconnection.
3. Use a multimeter to test the sensor's resistance; compare values to manufacturer specifications.
4. Clean any dirt or debris from the sensor and connector.

3. Check Brake Fluid and System

Tools Required: Brake fluid, funnel
Instructions:
1. Check the brake fluid reservoir; if low, fill it with the appropriate type of brake fluid (consult the owner's manual).
2. Inspect for any visible leaks around brake lines and calipers.
3. If leaks are found, repair or replace affected components.

4. Inspect the ABS Module

Tools Required: Socket set, multimeter, cleaning supplies
Instructions:
1. Locate the ABS module, typically found near the master cylinder.
2. Inspect the wiring harness and connectors for any signs of corrosion or damage.
3. Clean the connectors with electrical contact cleaner.
4. If faults are detected, consider replacing the ABS module.

5. Replace Wheel Speed Sensors (if necessary)

Tools Required: Socket set, torque wrench
Instructions:
1. Remove the wheel and tire assembly for access.
2. Unbolt the faulty wheel speed sensor from the hub assembly.
3. Install the new sensor and torque to manufacturer's specifications.
4. Reinstall the wheel and tire assembly.

6. Reconnect Battery and Clear Codes

Instructions:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear any existing error codes.
3. Start the vehicle and check if the traction control light is still illuminated.
