Solution

1. Preparation

Gather necessary tools and safety equipment.
Park the vehicle on a level surface, engage the parking brake, and disconnect the negative battery terminal.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
If necessary, remove the sensor bolts (usually Torx or Phillips screws) and gently pull out the sensors for a deeper clean.
Clean the sensors with brake cleaner and inspect for damage.

3. Check and Replace Brake Fluid

Open the master cylinder reservoir and check the fluid level; top off with the recommended brake fluid (typically DOT 4 for Volvo).
If the fluid is dark or contaminated, perform a brake fluid flush.
Bleed the brake lines to ensure no air is trapped in the system.

4. Repair or Replace Faulty Components

If diagnostic codes indicate a faulty ABS module, remove the module by disconnecting the wiring harness and unbolting it from the vehicle.
Install a new or refurbished ABS module, ensuring proper alignment and secure mounting.
If wheel speed sensors are faulty, replace them with new units.

5. System Reset and Testing

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes from the ABS system.
Conduct a road test to ensure the ABS light does not reappear and that the system functions correctly.
