Why is the AWD not working on my Subaru Outback?

Can a faulty VSS cause an AWD to not work?
Click to expand… Yes, a faulty VSS should trigger a code (32 or 33). For the most part, the solenoid could be ruled out because it’s normal failure mode is “off”, which will apply full pressure to the clutch piston; i.e. full clutch and full time rear drive.
