Quick check of TPMS
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.
The system can be checked, using the diagnostic tool, by activating a read off at the same time as activating the sensors using a special tool.
The special tool is placed against the tire in the place where the sensor is installed, at the same time as you push in a button on the special tool. Then the special tool sends out a signal that activates the sensor so that it starts to transmit signals to Upper Electronic Module (UEM). The activated sensor's ID-number and tire pressure are then shown on the display in the diagnostic tool.
