My 2007 S40 T5 AWD has had a few problems with AWD. The Anti-Skid light is on and only the front wheels work. The Haldex unit was replaced and still no luck. Vida shows that it’s not getting power but all connections are good. Any ideas?

1)did you replace haldex unit with the exact same part number & from confirmed working car?
2) did you check the haldex oil level? if its too low, AWD wont engage
3) did you check/replaced both pump and solenoid (that attached to haldex unit)? if one fails, it will also trigger warning

Seen all of those warnings and issues when fiddling with haldex controller swap, every part of the puzzle may trigger the error light
