Brake pressure sensor (Only DSTC)
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
Two brake pressure sensors are positioned on the master cylinder. One sensor is located on the primary circuit and one on the secondary circuit. The information is transmitted via two analog signals (measurement range 0-5 V) and is used by the ABS control module to calculate the brake pressure during DSTC control, and when the driver applies the brakes.
The sensors receive voltage via the ABS control module. There are diagnostics for the sensors.
When replacing the brake pressure sensor the ABS control module must be calibrated according to the information in VIDA vehicle communication or manually via a test drive.
