Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

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 brush or cloth.
Inspect the wiring harness for fraying or damage; repair as necessary.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for leaks in the brake lines or calipers.

4. Test the Traction Control Switch

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

5. Inspect ABS Module

Locate the ABS module under the hood.
Check for any loose connections or corrosion on the connectors.
If necessary, replace the ABS module by disconnecting it and removing mounting bolts.
