Signal specification
WARNING: This page is about a different car, the 2007 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
General
All the values given below are between the respective terminal in column 1 and terminal #A6 in column 1 (power ground), if this is not the case, it is indicated within brackets.
NOTE:
It is important to check ground terminals before taking readings.
| U= | DC voltage in volts (V) | UAC = | AC voltage in volts (V) |
| Ubat = | Battery voltage (V) | f = | Frequency in Hertz (Hz) |
| Ulow = | Voltage approximately 0 V | t = | Time in seconds |
| PWM = | Pulse width modulated signal as a % |
