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. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any ABS-related error codes for further analysis.

3. Inspect ABS Wheel Speed Sensors

Locate each wheel speed sensor (typically near the brake rotor).
Disconnect the electrical connector and inspect for corrosion or damage.
Clean the sensor and the sensor mount area with a suitable cleaner.
Reconnect the sensor and check the wiring for continuity using a multimeter.

4. Check ABS Control Module

Locate the ABS control module, usually near the master cylinder.
Inspect the module for signs of water damage or corrosion.
Ensure all connectors are securely attached and free from dirt or corrosion.

5. Brake Fluid Inspection

Check the brake fluid reservoir for the correct fluid level and condition.
If the fluid is low or contaminated, perform a brake fluid flush and replace with manufacturer-recommended fluid.

6. Brake Component Inspection

Remove the wheel to access the brake components.
Inspect brake pads and rotors for excessive wear; replace if necessary.
Ensure all components are properly assembled and tightened to manufacturer specifications.
