Brake Pressure Sensor (Only DSTC)
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. 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 analogue signals (measurement range 0-5 V) and is used by the brake control module (BCM) to calculate the brake pressure during active yaw control, and when the driver applies the brakes.
The sensors are supplied with voltage via the brake control module (BCM). There are diagnostics for the sensors.
When replacing the brake pressure sensor, the brake control module (BCM) must be calibrated according to the information in appropriate diagnostics tool vehicle communication or manually according to the test drive.
