Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Retrieve and Address Diagnostic Trouble Codes

Use an OBD-II scanner to read trouble codes.
Document any codes related to the traction control or ABS systems.
Clear the codes and perform a test drive to see if the traction control light returns.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any debris around the sensors and inspect the wiring for damage.
If damaged, replace the wheel speed sensors using the following steps:
- Remove the wheel and brake assembly for access.
- Disconnect the electrical connector and remove the sensor from the hub.
- Install the new sensor and reconnect the electrical connector.

4. Check ABS Module

Locate the ABS module and inspect for loose connections or corrosion.
If issues are found, repair or replace the ABS module as necessary:
- Disconnect the battery again.
- Remove any covers to access the ABS module.
- Disconnect the wiring harness and mounting bolts.
- Install the new ABS module and reconnect all connectors.

5. Verify Brake System Condition

Check brake fluid levels and top up if necessary with the recommended fluid type.
Inspect brake pads for wear. Replace if they are below the minimum thickness.
If worn, follow these steps:
- Remove the wheel.
- Remove the caliper bolts and lift the caliper off the rotor.
- Replace brake pads and reassemble the caliper.

6. Reconnect Battery and Final Checks

Reconnect the negative battery terminal.
Start the vehicle and check for warning lights.
Perform another OBD-II scan to ensure no codes remain.
