Sun roof (sun roof module (SRM))
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.
Connector A, terminals #A1-#A10
The following values are measured between the relevant terminal in column 1 and terminal #A5 (signal ground) unless otherwise stated.
U = DC in volts (V).
Ubat = battery voltage in volts (V).
Ulow = Voltage close to 0 V.
| Terminal, control module | Signal type | Ignition off Active/not active |
Ignition on Active/not active |
Other |
|---|---|---|---|---|
| #A1 | Power supply to the sun roof motor | Ubat | Ubat | - |
| #A2 | Sun roof forward, control signal | Ubat/0 V | Ubat/0 V | Pulsed signal when active. |
| #A3 | Sun roof tilt, control signal | Ubat/0 V | Ubat/0 V | Pulsed signal when active. |
| #A4 | Serial communication (Volcano lite) | Ubat | Ubat | The voltage is 0 V - Ubat during communication. Ubat is the default. |
| #A5 | Signal ground | Ulow | Ulow | - |
| #A6 | Power supply to the electronics in the sun roof module (SRM) | Ubat (for 5 minutes only according to the conditions on the right) | Ubat | Active when the ignition is off and neither of the front doors have been opened. |
| #A7 | Sun roof auto, control signal | Ubat/0 V | Ubat/0 V | Pulsed signal. Active when switching. |
| #A8 | Sun roof backward, control signal | Ubat/0 V | Ubat/0 V | Pulsed signal when active. |
| #A9 | Power supply to sun roof switch | Ubat/Ubat | Ubat/Ubat | Pulsed signal when active. |
| #A10 | Power ground | Ulow | Ulow | - |
