Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, cleaning supplies, brake fluid.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris using a soft cloth and cleaning solution.
Check the wiring harness connected to the sensors for any signs of wear or damage.
Reconnect the sensors securely.

3. Check ABS Control Module

Access the ABS control module, typically located near the brake master cylinder.
Inspect the wiring and connectors for any signs of corrosion or damage.
Use a multimeter to verify that the module receives the correct voltage.
If the module is malfunctioning, replace it with a factory-recommended part.

4. Brake Fluid Check

Inspect the brake fluid reservoir and ensure fluid is at the recommended level.
If low, top off with the appropriate type of brake fluid as per the owner's manual.
Look for any leaks in the brake lines or at the calipers.
