Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the sensor connector carefully.
4. Clean the sensor and the mounting area using a brake cleaner to remove dirt and debris.
5. Reconnect the sensor and reinstall the wheel.
6. Lower the vehicle and repeat for all four wheels.

3. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Inspect the fluid level; it should be between the minimum and maximum marks.
3. If low, add the appropriate brake fluid (DOT 4) until it reaches the correct level, ensuring not to spill on painted surfaces.

4. Inspect Wiring and Connectors

Sub-steps:
1. Visually inspect the wiring harnesses and connectors around the ABS module and wheel speed sensors.
2. Look for frayed wires, corrosion, or loose connections.
3. Repair or replace any damaged wiring or connectors as needed.

5. Clear Diagnostic Codes

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear any error codes related to the stability control system.
3. Start the vehicle and check if the stability control light remains off.
