Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush
Locate the wheel speed sensors on each wheel hub.
Remove the wheel if necessary for access.
Clean the sensors and surrounding areas with a cleaning brush to remove dirt and debris.
Reattach any connectors securely.

3. Check and Replace Brake Fluid (if necessary)

Tools Required: Brake fluid, funnel, rags
Inspect the brake fluid reservoir. If the level is low, add the appropriate type of brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush and replace with new fluid.

4. Test Brake Pedal Switch

Tools Required: Multimeter
Locate the brake pedal switch, usually mounted near the brake pedal.
Use a multimeter to check for continuity when the pedal is pressed.
If faulty, replace the switch with a new one.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored codes.
Start the vehicle and check if the traction control light remains illuminated.
