Solution

1. Preparation

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

2. Replace ABS Wheel Speed Sensors (if faulty)

Locate the ABS wheel speed sensors at each wheel hub.
Remove the wheel and tire assembly for easier access.
Unscrew the sensor mounting bolt using a socket wrench.
Carefully pull the sensor out of the hub; note its orientation for reinstallation.
Install the new ABS wheel speed sensor in the same orientation.
Refasten the mounting bolt to the manufacturer's torque specifications (usually around 8-10 Nm).
Reattach the wheel and tire assembly securely.

3. Repair or Replace ABS Module (if needed)

Remove the necessary components to access the ABS module, which may include the engine cover or other related parts.
Disconnect the electrical connectors and brake lines from the ABS module.
Unscrew the ABS module from its mounting location.
Install the new or repaired ABS module by reversing the removal steps.
Reconnect the brake lines and electrical connectors securely.

4. Reconnect Battery

Reconnect the negative battery terminal and ensure it is tightened securely.

5. System Reset

Use the OBD-II scanner to clear any stored ABS fault codes and reset the ABS system.
