Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any dirt or debris around the sensors using a soft cloth.
Disconnect the electrical connector from each sensor and inspect for corrosion or damage.
Reconnect the sensors and ensure they are securely fastened.

3. Check ABS Module

Locate the ABS module typically found near the brake master cylinder.
Inspect the wiring harness for any signs of damage or loose connections.
If an error code indicates a fault, replace the ABS module as per manufacturer specifications.

4. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level.
If low, top off with the manufacturer-recommended brake fluid type (usually DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush and replace with fresh fluid.

5. Traction Control Switch Check

Locate the traction control switch on the dashboard.
Test the switch for functionality; it should toggle the traction control system on and off.
If the switch is faulty, replace it with a new one.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and monitor the dashboard for the traction control light.
Test drive the vehicle to ensure the system operates correctly.
