Solution

1. Preparation

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

2. Inspect and Repair Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean the sensor area to remove any debris.
Disconnect the sensor connector and inspect for corrosion.
If damaged, replace the wheel speed sensors (part number as needed).
Reconnect the sensors and secure any loose wiring.

3. Check and Repair ABS Module

Locate the ABS module, which is typically near the brake master cylinder.
Inspect the ABS module for physical damage or leaks.
Check the wiring harness connected to the ABS module for signs of wear.
If necessary, replace the ABS module (part number as required).
Reconnect all connectors securely.

4. Test Brake Pedal Position Sensor

Locate the brake pedal position sensor, usually mounted on the brake pedal assembly.
Disconnect the sensor and test its operation using a multimeter.
If the sensor is faulty, replace it with a new one (part number may vary).
Reattach the sensor connector.

5. Reconnect Battery and Clear Codes

Reconnect the battery and ensure all connections are tight.
Use the OBD-II scanner to clear any stored trouble codes.
Start the vehicle and check if the traction control light remains off.
