Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove any dirt or debris surrounding the sensors.
3. Disconnect the electrical connector from each sensor.
4. Inspect the connectors for corrosion or damage.
5. Clean the sensor and connector contacts with electrical contact cleaner.

3. Check ABS Module

Sub-steps:
1. Reconnect the battery terminal and turn on the ignition.
2. Use the OBD-II scanner to retrieve ABS fault codes.
3. If codes indicate a specific fault, address that component (e.g., replace ABS module if necessary).

4. Test Brake Pedal Position Sensor

Sub-steps:
1. Locate the brake pedal position sensor near the brake pedal assembly.
2. Disconnect the sensor and use a multimeter to test for continuity.
3. Replace the sensor if it does not show continuity when the pedal is pressed.

5. Inspect Traction Control Switch

Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Remove the switch from the dashboard and inspect for any visible damage.
3. Test the switch with a multimeter to ensure it operates correctly.
4. Replace the switch if it is malfunctioning.

6. Reassemble and Test Drive

Sub-steps:
1. Reconnect all components and ensure all connectors are secure.
2. Reconnect the negative battery terminal.
3. Start the vehicle and check if the traction control light remains illuminated.
4. Perform a test drive under various conditions to ensure proper function.
