Solution

1. Preparation

Gather tools and materials needed for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any error codes related to the traction control or ABS systems.
Clear the codes and observe if they return after a test drive.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Clean the sensors and wiring connectors with electrical contact cleaner.
Check for continuity using a multimeter; replace any sensors that show no continuity.

4. Check Brake Fluid and ABS Module

Inspect the brake fluid reservoir, ensuring it is filled to the recommended level.
If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Inspect the ABS module for any visible signs of damage or leaks.

5. Test ABS Pump Operation

Turn the ignition key to the "On" position without starting the engine.
Listen for the ABS pump to activate; it should run briefly.
If the pump does not activate, further testing of the ABS module and wiring may be necessary.

6. Reassemble and Test Drive

Reinstall any components removed during inspection.
Lower the vehicle back to the ground.
Start the engine and take the vehicle for a test drive to verify that the traction control light is no longer illuminated.
