Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Wheel Speed Sensor Inspection

Locate the wheel speed sensors at each wheel.
Remove the wheel if necessary for better access.
Inspect the sensor and wiring for damage or disconnection.
Clean any dirt or debris from the sensor area.
Reconnect any loose connections and secure wiring.

3. ABS Module Inspection

Locate the ABS module, typically mounted on the brake master cylinder.
Check for any visible signs of damage or corrosion on the module and connections.
Clean the connectors with electrical contact cleaner.
Reconnect any loose connections firmly.

4. Traction Control Switch Test

Locate the traction control switch on the dashboard.
Remove the switch from its housing.
Use a multimeter to test for continuity when the switch is pressed.
Replace the switch if it does not function properly.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals ensuring they are tight.
Use the OBD-II scanner to clear any existing trouble codes.
Start the vehicle and check if the traction control message is still displayed.
