Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Disconnect the negative terminal of the battery to prevent any electrical shorts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Clean Wheel Speed Sensors

Locate each wheel speed sensor (usually mounted near the brake rotor).
Remove any dirt or debris around the sensor using a clean cloth.
If the sensor is damaged, proceed to replace it (see step 3).

3. Replace Faulty Wheel Speed Sensors (if necessary)

Use a socket set to remove the bolts securing the faulty wheel speed sensor.
Disconnect the electrical connector from the sensor.
Install the new wheel speed sensor by reversing the removal steps.
Torque the bolts to the manufacturer's specification (usually around 8-10 Nm).

4. Check and Refill Brake Fluid

Inspect the brake fluid level in the master cylinder reservoir.
If low, clean the area around the reservoir cap and remove it.
Fill with the appropriate brake fluid (DOT 4 is common for Volvo).
Replace the cap securely after filling.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal securely.
Use the OBD-II scanner to clear any stored ABS error codes.
Start the vehicle to check if the ABS warning light remains off.
