Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, electrical contact cleaner.
Locate the wheel speed sensors at each wheel hub.
Remove the sensor bolts using the socket set.
Carefully pull the sensor out and inspect for dirt or damage.
Clean the sensor and mounting area with a brush and electrical contact cleaner.
Reinstall the sensor and torque to manufacturer specifications.

3. Check ABS Module and Wiring

Tools Required: Multimeter, socket set.
Locate the ABS module, usually found near the brake master cylinder.
Inspect all wiring harnesses connected to the ABS module for frays or corrosion.
Use a multimeter to test the continuity of the wires leading to the wheel speed sensors.
Repair or replace damaged wires as necessary.

4. Refill Brake Fluid if Low

Tools Required: Brake fluid, funnel.
Check the brake fluid reservoir for proper fluid level.
If low, top off with the recommended brake fluid type (check owner's manual).
Ensure the cap is securely replaced.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals and ensure they are tight.
Use the OBD-II scanner to clear any existing trouble codes.
Start the vehicle and check if the traction control light remains illuminated.
