Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, vehicle jack, wheel chocks
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Retrieve and Analyze 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 any stored error codes related to the traction control system.
Document the codes for further analysis.

3. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Raise the vehicle using a jack and secure it with wheel chocks.
Locate the wheel speed sensors on each wheel hub.
Visually inspect the sensors for damage or dirt.
Use a multimeter to check the resistance of each sensor; compare with manufacturer specifications.
Replace any faulty sensors as necessary.

4. Check Brake Fluid and ABS Module

Check the brake fluid reservoir; ensure it is filled to the recommended level.
Inspect the brake lines for signs of leaks or damage.
Test the ABS module by using the OBD-II scanner to perform a functionality check.

5. Verify Stability Control Switch

Locate the stability control switch inside the vehicle.
Ensure it is not stuck in the "off" position or malfunctioning.
Replace the switch if it shows signs of failure.

6. Final Reassembly and Battery Connection

Reconnect the battery once all checks and repairs are complete.
Ensure all tools are removed from the work area.
Start the vehicle and check if the traction control light remains illuminated.
