Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris or dirt around the sensors.
Disconnect the sensor connectors and check for corrosion or damage.
Use a multimeter to test sensor resistance; they should typically measure between 1,000 to 2,000 ohms.

3. Check ABS Module

Remove the panel covering the ABS module.
Inspect the wiring and connectors for signs of wear or damage.
Use a scanner to check for specific fault codes related to the ABS module; address any codes found.

4. Test Traction Control Module

Access the traction control module (usually integrated within the ABS module).
Perform a function test using a compatible diagnostic tool to ensure it’s operating correctly.
Clear any stored codes and reset the system.

5. Reassemble and Test

Reconnect the battery terminal.
Start the vehicle and check if the traction control light remains illuminated.
Conduct a test drive to confirm the traction control system is functioning properly.
