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. Inspect Wheel Speed Sensors

Remove the wheel and tire assembly to access the brake assembly.
Inspect each wheel speed sensor for physical damage or loose connections.
Clean the sensor with brake cleaner if dirt or debris is present.
Reconnect any loose wiring and secure it properly.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, refill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).
If the fluid is contaminated, flush the brake system.

4. Test the ABS Module

Reconnect the battery and start the vehicle.
Use the OBD-II scanner to perform a functional test of the ABS module.
Check for any new or persistent trouble codes that may indicate module failure.

5. Replace Faulty Components

If any wheel speed sensors or the ABS module are found to be faulty, replace them with OEM parts.
- For wheel speed sensors: Disconnect the wiring harness, remove the mounting bolt, and replace with a new sensor.
- For the ABS module: Disconnect all wiring harnesses, unbolt the module, and install the new module in reverse order.
