Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the vehicle's battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, torque wrench, cleaning solvent, soft cloth.
Remove the wheel corresponding to the ABS light indication.
Locate the ABS wheel speed sensor and remove it from the hub assembly (typically secured with 10mm bolts).
Clean the sensor and its mounting area with a cleaning solvent and soft cloth.
Reinstall the sensor and torque bolts to manufacturer specifications.

3. Check Wiring and Connectors

Visually inspect the wiring harness leading to the ABS module and wheel speed sensors for fraying or damage.
Disconnect and reconnect connectors to ensure a secure connection.
If any wires are damaged, repair or replace them as necessary.

4. Test ABS Module

Tools Required: Multimeter, OBD-II scanner.
Reconnect the battery.
Use the OBD-II scanner to perform a communication test with the ABS module.
If the module is not responding, it may need replacement.

5. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level and condition.
If fluid is low, refill with the recommended brake fluid type (DOT 4 for most Volvo models).
Inspect brake lines for leaks, and repair as necessary.
