Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect Wheel Speed Sensors

Remove the wheel to gain access to the wheel speed sensor.
Use a multimeter to test the sensor’s resistance; it should typically be around 1,000 to 2,000 ohms.
Clean the sensor and its mounting area to remove any debris or corrosion.

3. Check ABS Control Module

Locate the ABS control module and visually inspect for any physical damage or burnt connections.
Reconnect the battery and use the OBD-II scanner to clear any existing fault codes.
Perform a function test of the ABS system by driving the vehicle at low speed and applying the brakes to check for normal operation.

4. Verify Traction Control Switch

Remove the switch from the dashboard panel.
Using a multimeter, check for continuity when the switch is pressed.
Replace the switch if it is found to be faulty.

5. Reassemble and Test

Reinstall any components removed during the inspection process.
Reconnect the battery and start the vehicle.
Test drive the vehicle to ensure the traction control light does not reappear and that the system functions correctly.
