What is the abs module on my 1998 Volvo s70?
The ABS module on your 1998 Volvo S70 is an electronic control unit that uses wheel speed sensors to monitor the speed of each wheel. When it detects a difference in wheel speed, it activates the ABS pump and valves to modulate the brake pressure to each wheel, preventing them from locking up. This allows the vehicle to maintain directional control.
