Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area using a clean cloth.
If damaged, replace the sensors using the following steps:
- Remove the mounting bolts with a socket set.
- Disconnect the electrical connector.
- Install the new sensor and reconnect the connector.

3. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it up with the recommended brake fluid type (DOT 4 for most Volvo models).
Ensure there are no leaks in the brake system.

4. Inspect ABS Module

Locate the ABS module under the hood.
Check for any visible signs of damage or corrosion.
If necessary, perform a continuity test using a multimeter to ensure proper function; replace if faulty.

5. Verify Traction Control Switch

Locate the traction control switch, usually found on the dashboard or center console.
Press the switch to toggle traction control on and off; listen for an audible click.
If the switch is unresponsive, replace it by removing the trim panel and disconnecting the electrical connector.
