Applies to the following models:
5 modelsS60 (2001–2009), S80 (1999–2006), V70 (2000–2008), V70 XC / XC70 (2001–2007), XC90 (2003–)
What does this fault code mean?
The code is set when the sun roof control module registers that SRM-0002 is set, at the moment contact is made with it. The sun roof motor then receives power even though the relay is switched off. A faulty relay can also be the cause. The automatic closing then does not work.
Possible causes
- The sun roof motor receives power although the relay is switched off
- Faulty relay
What you can do
- 1Run the sun roof to its outermost position and check that it can be used automatically.
- 2Read off the codes and clear them, then check whether SRM-0002 is still present.
- 3Check that the fuses for the sun roof are intact.
- 4If the fault remains, have a workshop replace the sun roof motor or control module as needed.
Symptoms you may notice1
