Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner.
Park the vehicle on a level surface, engage the parking brake, and disconnect the negative battery terminal for safety.

2. Inspect ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel hub.
Remove the sensor connector and inspect for damage or corrosion.
Clean the sensor and the mounting area with brake cleaner.
Reconnect the sensor and ensure it is securely fastened.

3. Check ABS Module and Wiring

Locate the ABS module, usually found near the master cylinder.
Visually inspect the wiring harness for frayed wires or loose connections.
Use a multimeter to check for proper voltage at the ABS module.
Repair or replace damaged wiring as necessary.

4. Verify Brake Fluid Level

Check the brake fluid reservoir for proper fluid level; it should be between the MIN and MAX marks.
If low, top up with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect brake lines and connections for any signs of leaks.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing fault codes.
Start the vehicle and check for any warning lights.
