Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensors using a soft cloth and appropriate cleaner.
Check the wiring harness for any signs of wear or damage.
Reconnect the sensors and secure the wiring properly.

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if it is low, add the manufacturer's recommended brake fluid type.
Inspect for any leaks in the brake lines or around the ABS module.

4. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Disconnect the switch and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new part.

5. Battery and Charging System Check

Use a multimeter to measure the battery voltage; it should be between 12.4V to 12.7V when the engine is off and around 13.7V to 14.7V when running.
If the voltage is outside these ranges, consider replacing the battery or addressing charging system issues.
