Signal Description
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.
All the values given below are measured between the respective connection in column 1 and connection 14 (signal ground) if not otherwise specified.
NOTE:
It is important that the test box is connected and the ground points checked before testing begins.
| U = | DC voltage (V) | f = | frequency in Hertz (Hz) | |
| Ubat = | battery voltage (V) | t = | period time in milliseconds (ms) | |
| Ulow = | Voltage close to 0 V | - | ||
