Tire Pressure Monitoring System (TPMS)

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.

The Upper electronic module (UEM) can store diagnostic trouble codes (DTCs) in the event of a fault on the actual receiver or on one of the sensors.

In order to perform a correct evaluation of the function, the vehicle must have traveled faster than 40 km/h (25 mph) for more than 570 seconds. This time is accumulated time, i. e. the time count stops if the vehicle travels slower than 40 km/h if, for example, you stop at traffic lights.

The count continues where it was as soon as the vehicle travels faster than 40 km/h once again.

Upper Electronic Module can store two diagnostic trouble codes per sensor. One diagnostic trouble code for lost communication and one diagnostic trouble code for low battery voltage. When a diagnostic trouble code is stored, the ID-number of the sensor to which the diagnostic trouble code applies is also stored.

When a diagnostic trouble code is stored, a message will be shown in the Driver information module.
