Solution

1. Preparation

Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any protective covers if applicable.
Clean the sensors using a soft cloth and electrical cleaner.
Reconnect any disconnected wiring and ensure secure connections.

3. Check Brake Fluid

Locate the brake fluid reservoir.
If the fluid is low, top it up with the manufacturer's recommended brake fluid (typically DOT 3 or DOT 4).
If the fluid appears contaminated, consider a brake fluid flush.

4. Examine ABS Module

Locate the ABS control module (usually near the brake master cylinder).
Inspect for any visible damage or loose connections.
If necessary, use a multimeter to test the module's power and ground circuits.

5. Replace Faulty Components

If diagnostic codes indicate a faulty wheel speed sensor or ABS module, replace the component.
Follow manufacturer specifications for torque settings during reinstallation.
