Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during the repair.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor mounting bolts using a socket wrench.
Carefully pull out the sensors from their housing.
Clean the sensors with an appropriate electrical cleaner to remove dirt or debris.
Reinstall the sensors, ensuring they are seated properly and secure the bolts to the manufacturer's torque specifications.

3. Check and Replace Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level and condition; if it is low or dirty, proceed to replace it.
Siphon out old brake fluid using a turkey baster or brake fluid pump.
Fill with new brake fluid that meets manufacturer specifications, ensuring it is at the correct level.

4. Inspect ABS Module

Access the ABS module, typically located near the brake master cylinder.
Check for any visible damage or corrosion on the wiring harness connected to the ABS module.
Use a multimeter to test the connections for continuity.
If faulty, replace the ABS module following the specific manufacturer instructions.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and check for the traction control light status.
Take the vehicle for a test drive to verify the system is functioning correctly.
