Solution

1. Preparation

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

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the cap and inspect the fluid level.
If low, top off with the manufacturer-recommended brake fluid (DOT 4 or as specified).

3. Inspect ABS Sensors

Raise the vehicle and secure it on jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Disconnect the sensor connector and visually inspect the wiring for damage.
Clean the sensor mounting area and ensure the sensor is properly seated in the hub.

4. Test ABS Module

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use the OBD-II scanner to check for fault codes related to the ABS module.
If codes indicate a faulty module, proceed to replace the ABS module.

5. Replace ABS Module (if necessary)

Disconnect the battery again.
Remove the necessary components to access the ABS module (e.g., air intake duct, connector covers).
Unscrew the ABS module mounting bolts using a socket set.
Disconnect the wiring harness from the ABS module and remove the module.
Install the new ABS module by reversing the removal steps, ensuring all connections are secure.
