Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to sit for a few minutes to ensure all systems are powered down.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors; they are typically found near the brake caliper on each wheel.
Remove any dirt or debris around the sensors using a clean cloth.
If damaged, remove the sensor using a socket set and replace it with a new one.
Reconnect the sensor harness securely.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect brake lines and connections for leaks; repair or replace damaged components as needed.

4. Inspect ABS Module

Locate the ABS module, usually mounted near the master cylinder.
Check for loose connections and damaged wiring.
If the ABS module is suspected to be faulty, consult the repair manual for replacement procedures.

5. Tire Inspection

Check each tire for proper inflation using a tire pressure gauge; inflate to the recommended PSI.
Inspect tread depth; replace tires that are worn beyond the safe limit.
Ensure tires are of the same type and size for optimal traction control performance.

6. Reset the Traction Control System

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes.
Reset the traction control system using the vehicle's menu or by disconnecting and reconnecting the battery.
