Signal specification
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
All the values listed below are between the terminal in column 1 and terminal #A53 (signal ground), unless otherwise indicated in brackets.
NOTE:
Connect the breakout box and check the ground connections before starting to measure.
| U = | DC voltage in volts (V) | UAC = | AC voltage in volts (V) |
| Ubat = | battery voltage | F = | frequency in Hertz (Hz) |
| Ulow = | voltage approximately 0 V | % duty = | duty cycle (pulse ratio) in percent (%) |
| t = | time in milliseconds (ms) |

Signal grounded in positions R, N, D, 3 | |
| #B5 | #A65 | Pressure sensor signal PS4 | Active = Ubat , Not active = 0 V | Pressure sensor PS4 is usually closed. It transmits a signal to the control module indicating the position of solenoid SL. When lock-up is requested, the pressure sensor must be Not active . When there is no lock-up, the pressure sensor must be Active . | |
| #B8 | #A68 | Control signal, shift solenoid S2 | Activated: U=0-2 V below Ubat Not activated: Ulow |
