Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a soft brush.
Clean the sensor connectors with electrical contact cleaner.
Reconnect the sensors securely.

3. Check and Top-off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, add the manufacturer-recommended brake fluid type to the appropriate level.
Check for leaks in the brake system that may cause fluid loss.

4. Inspect ABS Module and Wiring

Locate the ABS module, typically near the master cylinder.
Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
If visible damage is found, repair or replace the wiring as necessary.

5. Test Traction Control Switch

Locate the traction control switch (often near the center console).
Use a multimeter to check for continuity when the switch is activated.
If the switch is faulty, replace it with a new switch.

6. Test Drive and Clear Codes

Reconnect the battery and start the vehicle.
Use the OBD-II scanner to clear any existing fault codes.
Take the vehicle for a test drive to assess traction control functionality.
