Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth or compressed air.
If the sensors are damaged, replace them with new ones.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top it off with the manufacturer-recommended brake fluid.
Ensure there are no leaks from the brake lines or fittings.

4. Test and Replace Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Test the switch for continuity using a multimeter.
- If faulty, disconnect the wiring harness and remove the switch.
- Install a new brake pedal switch and reconnect the wiring.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored error codes related to the traction control system.
Turn on the ignition and verify if the traction control light is still illuminated.
