Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake cleaner, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Scan for Error Codes

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

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Check for signs of damage or wear on the wiring.
Use a multimeter to test the resistance of each sensor according to the manufacturer's specifications.
Clean any dirt or debris from the sensors and connectors.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid level is within the recommended range.
If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).
Inspect for any leaks in the brake lines or around the reservoir.

5. Inspect ABS Module

Locate the ABS module, typically found near the brake master cylinder.
Check for any visible damage or loose connections.
If necessary, use the OBD-II scanner to perform a reset on the ABS module.
Reconnect all components and ensure everything is secured.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check that the traction control light is no longer illuminated.
Perform a test drive to confirm the system is functioning correctly.
