Signal Specification
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 between the terminals stated in column 1 and terminal #D12 in column 2 (power ground). This applies unless otherwise indicated in the last column.
NOTE:
It is important to connect the breakout box and check the ground connections before starting to measure.
| U= | DC voltage in volts (V) | t = | Time in milliseconds (ms) |
| Ubat = | Battery voltage (V) | f = | Frequency in Hertz (Hz) |
| Ulow = | Voltage approximately 0 V | % duty | Duty cycle (pulse ratio) as a percentage (%) |
