Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors.
Disconnect the electrical connectors and visually inspect for damage.
Use a multimeter to test the resistance of each sensor (should be within manufacturer specifications).

3. Check Brake Fluid and System

Inspect the brake fluid reservoir; refill with the recommended brake fluid if low.
Look for leaks in the brake lines and around the calipers.
Replace any damaged components as necessary.

4. Test ABS Control Module

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use a multimeter to check the power supply to the ABS module.
If no power is detected, trace the wiring back to the fuse box and check for blown fuses.

5. Reassemble and Clear Codes

Reconnect any disconnected sensors and ensure all connections are secure.
Reconnect the battery.
Use the OBD-II scanner to clear any error codes.
