Wheel speed, value

WARNING: This page is about a different car, the 2006 Volvo S80 and 2005 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.

The value indicates wheel speed.

The brake control module (BCM) transmits the vehicle speed signal on the controller area network (CAN) and the differential electronic module (DEM) uses the signal to control four wheel drive.

Measurement range: 0 - 255 km/h.
