Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove the sensor mounting screws using a socket set.
3. Carefully pull the sensor from its housing and inspect for dirt or damage.
4. Clean the sensor with a soft cloth and appropriate cleaner.
5. Reinstall the sensor and tighten the screws to the manufacturer's torque specifications (typically around 10-15 Nm).

3. Check and Replace ABS Fuse (if necessary)

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Identify the ABS fuse using the diagram on the fuse box cover.
3. Remove the fuse and inspect it for continuity; replace if blown with a fuse of the same amperage.

4. Inspect Wiring and Connectors

Sub-steps:
1. Trace the wiring from the wheel speed sensors to the ABS module.
2. Look for any signs of fraying, corrosion, or damage.
3. Clean any corroded connectors with electrical cleaner and reconnect securely.

5. Test Drive and Reconnect Battery

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle and conduct a test drive to ensure the traction control light is off and the system operates correctly.
