quite likely, the drive is inhibited due to a problem with the seating system.
It could be as simple as a blown fuse, broken wire in a cable, or something unplugged, or as bad as a bad actuator or seat control (ICS) master module.
Depending on the configuration of the seat, the drive speed is reduced, or inhibited completely-to comply with various ISO and other legal regulations.
The ICS Master Module, monitors the seat position, and tells the power module, to drive and how fast.
If the power module doesn't get the signal from the ICS master, it will not drive.
If Rnet isn't showing any error, I would bet the ICS master signal is the issue.
I believe your ICS master has lost power, (there is a 20 amp fuse on the board), or has gotten uplugged/broken wire, or has just plain gone bad, and will require replacement. A bad actuator can cause the fuse to blow.
Aside from the fuse, there really isn't anything user friendly as far as repair-other than check for something unplugged.
I don't have an owners manual here, but it might show you where the ICS master is located
Good luck
