Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solution, and a soft brush.
Remove the wheel associated with the illuminated traction control light.
Locate the wheel speed sensor mounted on the wheel hub.
Carefully disconnect the sensor's electrical connector.
Remove the sensor using the appropriate socket size.
Clean the sensor tip with a soft brush and cleaning solution to remove any debris.
Reinstall the sensor and reconnect the electrical connector.
Repeat for all wheel speed sensors if necessary.

3. Check ABS Control Module

Tools Required: Multimeter, OBD-II scanner.
Reconnect the battery and turn on the ignition.
Use the OBD-II scanner to check for ABS module error codes.
If codes are present, note them down for further investigation.
If no codes are found, proceed to check the ABS module's connections and wiring for any signs of damage.

4. Test Brake Pedal Switch

Tools Required: Multimeter.
Locate the brake pedal switch on the brake pedal assembly.
Disconnect the switch connector and use a multimeter to test for continuity while pressing the brake pedal.
If the switch is faulty, replace it with a new one.

5. Verify Traction Control Switch

Tools Required: OBD-II scanner.
Use the OBD-II scanner to monitor the status of the traction control switch.
Ensure that the switch is functioning correctly and that it is not stuck in the 'off' position.
