Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, brake cleaner
Sub-steps:
1. Remove the wheel to access the wheel speed sensors.
2. Disconnect the sensor connector from the vehicle harness.
3. Remove the wheel speed sensor from its mount.
4. Clean the sensor and mounting area using a cleaning brush and brake cleaner.
5. Reinstall the sensor and reconnect the wiring.

3. Check ABS Module and Wiring

Tools Required: Multimeter, socket set
Sub-steps:
1. Locate the ABS module and inspect for physical damage or corrosion.
2. Use a multimeter to test the wiring continuity to ensure there are no breaks.
3. If damaged, replace the wiring harness or module as necessary.

4. Brake Fluid Inspection and Replacement

Tools Required: Brake fluid tester, syringe or brake bleeder
Sub-steps:
1. Check the brake fluid level in the reservoir and inspect for contamination.
2. If fluid is low or contaminated, remove old fluid using a syringe or brake bleeder.
3. Refill the reservoir with the manufacturer-recommended brake fluid type (usually DOT 4).
4. Bleed the brake system to remove air bubbles and ensure proper fluid flow.

5. Reconnect Battery and Clear Codes

Tools Required: Wrench for battery terminals
Sub-steps:
1. Reconnect the battery terminals securely.
2. Use the OBD-II scanner to clear any stored fault codes related to stability control.
3. Start the vehicle and check for warning lights.
