Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent 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 soft cloth.
If necessary, remove the sensor bolts with a socket set and gently pull out the sensor to inspect for damage.
Clean the sensor connectors with electrical contact cleaner.

3. Check Brake Pedal Switch

Locate the brake pedal switch, usually mounted on the brake pedal assembly.
Inspect the switch for proper operation; it should engage when the pedal is pressed.
If faulty, remove the switch by disconnecting its wiring and unscrewing it from the assembly.
Replace with a new switch if needed.

4. Inspect ABS Control Module and Wiring

Locate the ABS control module, typically found near the brake master cylinder.
Visually inspect for any signs of corrosion or damage on the module and its connectors.
Use a multimeter to test the module's power and ground connections according to the service manual specifications.
Repair or replace any damaged wiring as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Start the vehicle and check if the traction control light remains illuminated.
If the light is still on, further diagnostics may be required to identify deeper issues such as a faulty ABS module.
