Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position without starting the engine.
Retrieve and note any error codes related to the traction control system.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connectors and remove the sensors using a socket set.
Clean the sensor mounting area and inspect the sensors for damage or debris.
Reinstall or replace damaged sensors.

4. Check ABS Control Module

Locate the ABS control module, typically near the brake master cylinder.
Inspect for any signs of corrosion or loose connections.
If necessary, clean the connections with electrical contact cleaner and ensure they are tight.

5. Test Brake Pedal Switch

Locate the brake pedal switch, typically mounted on the brake pedal assembly.
Disconnect the switch and use a multimeter to test for continuity when the pedal is pressed.
Replace the switch if it does not function correctly.

6. Final Checks

Reconnect the battery terminal.
Clear any stored codes using the OBD-II scanner.
Start the engine and check for the traction control light.
