Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Turn off the ignition and disconnect the battery (negative terminal first).
Gather necessary tools and parts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors.
Check the wiring for frays or disconnections.
Use a multimeter to test the resistance of each sensor (should be within manufacturer specifications).

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level and top it off with the correct brake fluid type if low.
If the fluid is contaminated, consider flushing the brake system.

4. Examine ABS Module

Locate the ABS module, typically near the master cylinder.
Check for any visible leaks or corrosion.
Reconnect any loose wiring harnesses to the module.

5. Inspect Tires

Check tire pressure using a tire pressure gauge and inflate to recommended levels.
Inspect for uneven wear, which may indicate alignment issues.
Replace any damaged or excessively worn tires.

6. Reconnect Battery and Test

Reconnect the battery (positive terminal first).
Start the vehicle and observe if the traction control light remains illuminated.
Take the vehicle for a test drive in a safe area to check for proper traction control function.
