Solution

1. Preparation

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

2. Scan and Clear Error Codes

Use an OBD-II scanner to read and document any error codes.
Clear the codes and check if they return after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt around the sensors.
Check the sensor wiring for fraying or disconnection.
If damaged, replace the wheel speed sensors.

4. Check ABS Module

Access the ABS module, usually located near the master cylinder.
Inspect the wiring and connections for any signs of damage.
If the ABS module is faulty, replace it according to manufacturer specifications.

5. Brake Fluid Inspection

Open the brake fluid reservoir and check fluid levels.
If low, top up with the recommended brake fluid type as specified in the owner’s manual.
Look for leaks in the brake lines or around the master cylinder.

6. Battery Voltage Check

Use a multimeter to check the battery voltage; it should be around 12.6 volts when the vehicle is off.
If the voltage is low, charge the battery or replace it if necessary.
