Solution

1. Preparation

Gather tools and necessary replacement parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery's negative terminal to prevent electrical shorts.

2. Inspect and Clean ABS Wheel Speed Sensors

Remove the wheel corresponding to the affected sensor.
Locate the ABS wheel speed sensor on the wheel hub.
Clean the sensor and its connector using electrical contact cleaner to remove dirt and debris.
Reconnect the sensor and ensure it is securely in place.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, refill with the manufacturer's recommended brake fluid (typically DOT 4).
Check for signs of leaks in the brake lines or at the master cylinder.

4. Examine Wiring and Connectors

Inspect the wiring harness leading to the ABS module for fraying or damage.
Look for loose or corroded connectors; clean or replace as necessary.
Ensure all connections are tight and secure.

5. Reconnect Battery and Clear Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and observe if the stability control light turns off.
