Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter, cleaning brush.
Remove the wheel covering the suspected wheel speed sensor.
Disconnect the sensor's electrical connector.
Use a multimeter to check the sensor's resistance; it should typically be between 1,000 to 2,000 ohms.
Clean the sensor and surrounding area with a brush to remove any debris.
Reconnect the sensor and wheel.

3. Check Traction Control Fuse

Tools Required: Fuse puller or pliers.
Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the fuse related to the traction control system using the fuse diagram.
Remove the fuse and inspect it for continuity; replace if blown.

4. Inspect ABS Module

Tools Required: Socket set, multimeter.
Check the ABS module connections for corrosion or damage.
Test the wiring harness for continuity using a multimeter, ensuring proper connectivity.
If there are any faults, replace the ABS module or repair the wiring.

5. Reconnect Battery

Reconnect the battery terminal securely.
Ensure no tools are left in the engine bay.

6. Clear Error Codes

Use an OBD-II scanner to clear any error codes related to the traction control system.
Start the vehicle and observe if the traction control light remains off.
