Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris or dirt around the sensors.
Disconnect the electrical connector from the sensor.
Clean the sensor with a suitable electronic cleaner.
Reconnect the electrical connector and ensure it is secure.

3. Check ABS Module

Access the ABS module, usually located near the brake master cylinder.
Inspect for any visible damage or corrosion on the connectors.
If necessary, disconnect and clean the connectors with electronic cleaner.
Reconnect the module ensuring a secure connection.

4. Repair/Replace Faulty Components

Based on diagnostic results, replace any faulty wheel speed sensors or ABS module if required.
Use OEM or high-quality replacement parts to ensure compatibility.

5. Reset the TCS System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes from the TCS and ABS systems.
Turn on the ignition without starting the engine to allow the system to reset.

6. Test Drive

Conduct a test drive to ensure the traction control system operates correctly.
Monitor the dashboard for any warning lights and check for proper TCS functionality.
