Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent any electrical shorts.
Allow the vehicle to sit for a few minutes to ensure all systems are powered down.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Scan for any traction control-related error codes.
Write down the codes, then clear them to see if they return after a test drive.

3. Inspect and Clean Wheel Speed Sensors

Remove the wheel covering the sensor.
Disconnect the wiring harness from the wheel speed sensor.
Clean the sensor with brake cleaner to remove any debris or dirt.
Reinstall the sensor and reconnect the wiring harness.

4. Check ABS Module

Locate the ABS module, typically found near the brake master cylinder.
Visually inspect for any signs of corrosion or loose connections.
If needed, perform a continuity test on the ABS module connections with a multimeter.

5. Verify Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the markings on the reservoir; top off with the recommended brake fluid if low.
Inspect for any leaks in the brake lines or around the reservoir.

6. Traction Control Switch Test

Locate the traction control switch on the dashboard.
Remove the switch from the dash and test it with a multimeter for continuity.
Replace the switch if it is faulty.
