Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is parked on a flat surface, and the ignition is off before starting the repair.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub assembly.
Remove the sensor mounting bolts using the socket set.
Carefully detach the sensors and inspect for dirt or damage.
Clean the sensors with an appropriate electronic cleaner and a soft cloth.
Reinstall the sensors, torqueing the bolts to manufacturer specifications.

3. Check ABS Module and Wiring

Locate the ABS module, typically found near the master cylinder.
Inspect the wiring harness for any frayed wires or loose connections.
Use a multimeter to test for continuity in the wiring.
If damaged, repair or replace the wiring as necessary.

4. Verify Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended brake fluid type.
Inspect for any leaks in the brake system that may have caused fluid loss.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
If the switch is faulty, replace it with a new one.
