why is my Skoda Octavia's traction control light on

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.
