Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.
Disconnect the battery to avoid any electrical issues during repairs.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's instructions to retrieve and record any error codes related to traction control or ABS.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Visually inspect the sensors and wiring for any signs of damage or corrosion.
Clean any dirt or debris from the sensor area using a soft cloth.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the correct level; if low, top it off with the manufacturer's recommended brake fluid.
If the fluid appears dirty or contaminated, consider performing a brake fluid flush.

5. Examine ABS Module

Locate the ABS module, typically mounted near the master cylinder.
Check all wiring connections to ensure they are secure and free of corrosion.
If error codes indicate a fault, replace the ABS module as necessary, following specific manufacturer guidelines.

6. Test Drive

Reconnect the battery and start the engine.
Test drive the vehicle in a safe area to observe if the traction control light remains off and the system functions correctly.
