Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensors and their connectors.
Check the wiring for frays or disconnections.
If damaged, replace the sensors with new ones (ensure they are OEM or compatible).

3. Brake Fluid and Lines Check

Inspect the brake fluid reservoir for proper fluid level.
If low, refill with the recommended brake fluid (DOT 3 or DOT 4 as specified).
Look for any leaks in the brake lines, especially near the ABS module.
Repair or replace any damaged lines.

4. ABS Module Inspection

Locate the ABS module, usually near the master cylinder.
Inspect the wiring harness for signs of wear or corrosion.
If necessary, use a multimeter to test the continuity of the wiring.
If malfunctioning, replace the ABS module.

5. Traction Control Switch Test

Locate the traction control switch on the dashboard.
Remove the switch from the panel and test it using a multimeter (check for continuity when pressed).
Replace the switch if it is faulty.

6. Tire Condition Check

Inspect all tires for uneven wear and proper tread depth.
Ensure all tires are inflated to the manufacturer's recommended pressure.
Replace any tires that are worn beyond safe limits.
